The Cryptographic Debt Crisis: A Deep-Dive into Quantum Vulnerabilities within Enterprise Repositories

Enterprise repositories across the globe from foundational cryptographic libraries (OpenSSL) to runtime environments (Node.js), database systems (PostgreSQL), and content management platforms (WordPress) are embedded with classical cryptography algorithms that will become obsolete within the quantum computing era.

This technical case study presents QScan CBOM audit findings revealing that 596+ cryptographic assets in OpenSSL, 1,138 in Node.js, and 153 in WordPress remain vulnerable to "Harvest Now, Decrypt Later" (HNDL) attacks, where adversaries collect encrypted data today to retroactively decrypt it using quantum computers by 2030. Concurrently, India's Digital Personal Data Protection (DPDP) Act 2023 with full enforcement commencing May 13, 2027 redefines organizational liability to include "reasonable security safeguards" (Section 8(5)).

The convergence of these forces creates a cryptographic debt crisis: organizations continuing to deploy RSA-2048, ECDSA, and MD5 hashing in 2026, when NIST FIPS 203-205 post-quantum standards are operationally available, face simultaneous exposure to quantum decryption risk and regulatory penalties reaching ₹250 crores.

This study argues that inaction is not a neutral position it is a documented failure of duty under Indian law, converting quantum vulnerability into a present compliance liability.

Part I: The Quantum Apocalypse Has Already Begun, Harvest Now, Decrypt Later Threat

The Mathematics of Quantum Collapse

Shor's Algorithm, formalized in 1994, proved that a quantum computer with approximately 2,000-4,000 error-corrected logical qubits could factor large integers exponentially faster than any classical algorithm. This mathematical certainty is not theoretical speculation; it is peer-reviewed, NIST-endorsed, and increasingly operationalized. Today's RSA-2048, protecting approximately 112 bits of effective security against classical computers, collapses to 33 bits when subjected to Shor's algorithm on a quantum computer a reduction factor of over 100x.​

The timeline is crystallizing. In 2024, researchers refined Shor's circuit designs, with estimates converging around 1,000-2,000 error-corrected qubits sufficient to break RSA-2048 with practical runtimes. Experts, including those affiliated with NIST and academia, consensus on 2030 as the cryptanalytically relevant quantum computer (CRQC) benchmark a date just four years from today (January 2026).​

Simultaneously, quantum computing development is accelerating. IBM, Google, IonQ, and state actors are operating quantum processors exceeding 100-1,000 qubits. The United States, European Union, and China are investing tens of billions in quantum research. The quantum threat is not a future apocalypse; it is a present inflection point.

HNDL: The Silent Heist Underway

Beneath the surface of classical cybersecurity alertness, a patient, methodical attack is unfolding: Harvest Now, Decrypt Later (HNDL). The strategy is elegantly simple but catastrophically consequential:​

Stage 1 - Harvest (2025-present): Threat actors nation-states, organized criminal syndicates, and sophisticated non-state actors systematically intercept and store encrypted data without attempting immediate decryption. They collect:

• API payloads between microservices (containing authentication tokens, session keys)
• TLS handshakes and encrypted traffic from banking platforms, fintech APIs, and payment processors
• Database backups, encrypted archives, and source code repositories stored in cloud services
• VoIP communications, email archives, and proprietary business intelligence transmitted over encrypted channels

For India's fintech ecosystem processing billions of UPI transactions, storing encrypted Aadhaar-linked identities, managing confidential credit assessments this is an active, ongoing threat. Threat actors do not need to breach the decryption barriers today; they only need to passively capture and store.​

Stage 2 - Decrypt (2030+): Once quantum computers mature, stored encrypted datasets become transparently readable. Data that was "secure" for 5-10 years is retroactively exposed. Aadhaar numbers, PAN details, banking credentials, transaction histories, and proprietary AI models all become visible.

The HNDL threat creates a retroactive liability window. Data encrypted today with RSA-2048 or ECDSA has an implicit "decryption deadline" of approximately 2030-2035. Any data with a retention obligation exceeding this window (e.g., financial records retained for 7-10 years, health data retained for lifetime) faces certain exposure if encrypted with classical algorithms.

QScan CBOM Audit Findings: Quantum Vulnerability at Enterprise Scale

OpenSSL (596 cryptographic assets, Quantum Score: 0.0/10):

• VULNERABLE_HASH: 28 instances (SHA-1, MD5, RIPEMD-160) detected in /apps/rehash.c, /apps/ocsp.c, /apps/crl.c, and /crypto/md5/md5_one.c
• VULNERABLE_ASYMMETRIC: 15 instances (prime256v1 ECDSA, DSA signatures) in /apps/ecparam.c, /ssl/t1_lib.c, indicating default TLS cipher suites vulnerable to Shor's algorithm
• TRANSITIONAL_SYMMETRIC: 18 instances (AES-128, 3DES, Blowfish) subject to Grover's algorithm speedup, weakening key space by 50%

OpenSSL is the cryptographic backbone of modern internet infrastructure. Every HTTPS connection, SSH session, and TLS handshake touching OpenSSL depends on classical algorithms. When a fintech application running on Linux connects to an AWS API endpoint, that connection negotiates cipher suites determined by OpenSSL's default configurations configurations hardcoded with 20-year-old mathematics.​

Node.js (1,138 cryptographic assets, Quantum Score: 0.0/10):

• VULNERABLE_ASYMMETRIC: 12 instances (DiffieHellman in /lib/crypto.js, /lib/internal/crypto/diffiehellman.js, prime256v1 curves in /lib/internal/crypto/util.js)
• TRANSITIONAL_SYMMETRIC: 45 instances (AES-128, ChaCha20 in benchmark and internal crypto modules)
• STRONG_SYMMETRIC: 120 instances (AES-256) a positive signal, but overwhelmed by weaker algorithms

Node.js powers millions of fintech microservices, payment gateways, and real-time trading platforms across India and globally. The presence of DiffieHellman in the core crypto module means every Node.js application relying on key exchange is architecturing on Shor's-vulnerable foundations.​

PostgreSQL (45 cryptographic assets, Quantum Score: 3.2/10):

• VULNERABLE_HASH: 12 instances (MD5 in crypt-md5.c, SHA-1 in pgp-pubkey.c, authentication functions)
• TRANSITIONAL_SYMMETRIC: 12 instances (Blowfish in crypt-blowfish.c and pgcrypto/openssl.c, 3DES in pgp.c)
• STRONG_SYMMETRIC: Only 2 instances (AES-256)

PostgreSQL's pgcrypto extension is widely used to encrypt sensitive columns (PAN numbers, health records, biometric data) before writing to disk. Organizations relying on Blowfish or 3DES for field-level encryption face retroactive exposure: if a database backup is stolen today, that backup's contents become plaintext when quantum computers arrive. The data shelf-life problem is acute: a healthcare provider encrypting patient records with Blowfish in 2026, with a 20-year retention obligation, will see that data decrypted while still legally required to protect it.​

WordPress (153 cryptographic assets, Quantum Score: 0.0/10):

• VULNERABLE_HASH: 78 instances (MD5 hash functions) throughout /wp-admin/update-core.php, /wp-admin/includes/plugin-install.php, and core WordPress functions
• GENERIC_CRYPTO_LIB: 28 instances (generic crypt() calls, openssl_encrypt functions)

MD5 is cryptographically broken. Collision attacks against MD5 are practical on classical computers today, let alone quantum computers. Yet WordPress—powering over 40% of all websites globally, including countless fintech information portals continues to rely on MD5 for integrity checks in plugin updates and core file verification. A WordPress-based fintech blog announcing earnings or payment infrastructure changes uses MD5-verified plugin code.​

React (2 cryptographic assets, Quantum Score: 9.5/10):

• Minimal cryptographic footprint; vulnerable elements inherited from type definitions, not core library

React's high quantum score reflects its architectural design principle: frontend frameworks should not implement cryptography. Cryptography must remain at the backend layer where it can be audited, upgraded, and controlled. React's minimal surface area is a design virtue, not a security guarantee for the applications built on it.

Part II: The DPDP Act 2023 and the Negligence Trap Regulatory Liability Redefined

From Safe Harbor to Negligence Doctrine

India's Digital Personal Data Protection (DPDP) Act 2023 fundamentally redefines organizational liability for data security. Unlike the Information Technology (IT) Act 2000 which provided a safe harbor to organizations implementing "reasonable security practices"—the DPDP Act inverts the burden: organizations must now prove they have implemented "reasonable security safeguards" and can lose safe harbor status if demonstrably negligent.​

Section 8(5) mandates:

"A Data Fiduciary shall protect personal data, including any processing undertaken by it or on its behalf by a Data Processor, by taking reasonable security safeguards to prevent Personal Data Breach."

This provision is deceptively straightforward but legally revolutionary. "Reasonable" in 2026 is objectively defined by available standards, not by organizational resources. NIST FIPS 203-205 (ML-KEM, ML-DSA, SLH-DSA) were published in August 2024. As of January 2026, these standards are operationally implemented in AWS-LC FIPS 3.0, open-source libraries, and commercial cryptographic toolkits.​

An organization continuing to deploy RSA-2048, ECDSA, or MD5 in 2026—after NIST standards are available, after vendor implementations exist, and after the Data Protection Board is operational—can be held liable for a conscious choice to maintain quantum-vulnerable cryptography.

Enforcement Timeline: 18 Months to Full Penalty Authority

The DPDP Act enforcement follows a structured three-phase timeline:​

Phase 1 (November 14, 2025 - Effective): Data Protection Board (DPB) is constituted; administrative provisions active. No immediate compliance burden on data fiduciaries, but the regulator is standing up its enforcement infrastructure.

Phase 2 (November 14, 2026 - 12 months): Consent Manager framework opens for registration. Companies begin deploying consent and privacy notice mechanisms. DPB gains oversight authority over Consent Managers.

Phase 3 (May 13, 2027 - 18 months from gazette): ALL substantive obligations become enforceable with NO GRACE PERIOD. Penalties apply immediately.

This means:

• By May 13, 2027, data fiduciaries must have implemented "reasonable security safeguards."
• The DPB, fully staffed and operationalized by May 2027, will begin enforcement actions.
• Penalties of up to ₹250 crores for violations of Section 8(5) (failure to implement reasonable security safeguards) or Section 30 (failure to report data breach within 72 hours).​

The Negligence Doctrine: Quantum Readiness as a Legal Obligation

Here is the critical enforcement mechanism: Under Indian administrative and tort law, negligence is established when:

A duty of care exists (✓ Section 8(5) establishes this)

The duty-holder failed to exercise reasonable care (✓ Continuing to use RSA-2048 after NIST standards are available)

The failure caused injury (✓ Quantum decryption of stored personal data)

The DPDP Act Board, when adjudicating a data breach case, will ask: "In 2026-2027, when NIST ML-KEM standards were available, vendor implementations existed, and the organization had 18 months to plan, why did they continue deploying RSA-2048?"

If the organization cannot provide a technical justification (e.g., "legacy systems required 2-year transition"), the Board will classify the failure as negligence, removing the organization's safe harbor status and exposing it to maximum penalties.

The Significant Data Fiduciary (SDF) Escalation

Certain organizations—banks, fintech platforms, payment processors, healthcare providers, insurance companies—will be classified as Significant Data Fiduciaries (SDFs) under the DPDP Act. SDFs face enhanced obligations:​

• Mandatory appointment of a Data Protection Officer with C-suite accountability
• Mandatory Data Protection Impact Assessments (DPIAs) for high-risk processing (e.g., financial transactions, health data)
• Mandatory cryptographic audits (via QScan or equivalent CBOM tools)
• Documented migration roadmaps showing transition from quantum-vulnerable to quantum-resistant cryptography

For an SDF processing UPI transactions, Aadhaar-linked identities, or health records:

• A CBOM audit documenting quantum-vulnerable algorithms becomes a compliance artifact
• The absence of a post-quantum migration roadmap becomes evidence of negligence
• Continuing classical cryptography without documented justification becomes a breach of duty of care

Part III: Cryptographic Bill of Materials (CBOM) as a Compliance Foundation

Why CBOM Matters for DPDP Act Compliance

A Cryptographic Bill of Materials (CBOM) is a CycloneDX-compliant inventory of all cryptographic algorithms, key management practices, and cryptographic configurations deployed across an organization's infrastructure.​

For DPDP Act compliance, a CBOM serves as:

Regulatory Transparency: The DPB expects organizations to provide a complete picture of cryptographic controls. A CBOM is the primary evidence of this control inventory.

Risk-Based Prioritization: A CBOM enables organizations to segment systems by data sensitivity:

• High-priority: Systems storing Aadhaar, PAN, health data, financial credentials (require immediate PQC migration)
• Medium-priority: Systems processing transaction metadata, authentication logs (require phased migration)
• Low-priority: Frontend applications, public-facing analytics (lower urgency)

Vendor Due Diligence: The DPDP Act requires due diligence on Data Processors (cloud providers, payment gateways, third-party APIs). A CBOM reveals which vendors are introducing quantum-vulnerable cryptography into the supply chain.

Audit Evidence: When the DPB investigates a data breach, the organization's CBOM and accompanying migration roadmap serve as evidence of either reasonable care (mitigation) or negligence (inaction).

QScan CBOM: Granular Findings for Actionable Remediation

QScan's CBOM generation provides precise file-level and function-level cryptographic discovery, enabling development teams to execute targeted remediation without entire system rewrites.

Example - WordPress CBOM Finding:

textAlgorithm: MD5 (VULNERABLE_HASH) Category: Weak Hashing Function (Collision-vulnerable) Locations: - /wp-admin/update-core.php (5 instances) - /wp-admin/includes/plugin-install.php (3 instances) - /wp-admin/includes/misc.php (7 instances) - /wp-admin/includes/file.php (2 instances) Risk: HIGH - Collision attacks feasible on classical computers; retroactive exposure via HNDL Remediation: Migrate to SHA-256 or NIST-standardized hash (SHA-3, BLAKE2) Timeline: Phase 1 (Q1-Q2 2026)

This granularity enables a WordPress development team to prioritize: "We have 40 MD5 instances across plugin integrity checking. We can migrate these to SHA-256 in Q2 2026 without touching other components."

Example - PostgreSQL CBOM Finding:

textAlgorithm: Blowfish (TRANSITIONAL_SYMMETRIC) Category: Symmetric Crypto <256 bit (Grover's algo weakens) Locations: - /contrib/pgcrypto/crypt-blowfish.c (8 instances) - /contrib/pgcrypto/openssl.c (4 instances) Data Sensitivity: CRITICAL (PAN, health records, biometrics encrypted using pgcrypto('blowfish', ...)) Risk: CRITICAL - Data shelf-life problem: encrypted data valid for 20+ years; decryptable in 2030 Remediation: - For new data: Use AES-256 or eventually ML-KEM-derived keys - For existing data: Key rotation + re-encryption strategy (Q3-Q4 2026) Timeline: Phase 2 (Q3-Q4 2026) for data-at-rest migration

This finding directly informs regulatory compliance: An SDF storing encrypted health records with Blowfish must demonstrate (by May 2027) that it has migrated to quantum-safe algorithms or has a documented re-encryption plan. The CBOM is the evidence.

Part IV: The Legacy Loop and Data-at-Rest Trap

The OpenSSL Inheritance: Quantum Vulnerability by Default

OpenSSL is a paradox: it is simultaneously the most widely deployed cryptographic library on the internet and the oldest, with embedded classical algorithms. Every modern application built in 2025-2026—using contemporary frameworks, cloud-native architectures, containerized deployments—inherits OpenSSL's cryptographic footprint by default.​

When a fintech startup:

• Deploys Node.js on AWS Lambda (Node.js depends on OpenSSL)
• Uses HTTPS for API endpoints (Apache/NGINX depends on OpenSSL)
• Connects to PostgreSQL (TLS handshake uses OpenSSL)
• Authenticates users via SSH (OpenSSL primitives)

...it is automatically importing 596 cryptographic assets, 43 of which are vulnerable to Shor's or Grover's algorithms. This is not a choice; it is a default inheritance of cryptographic debt.

The OpenSSL codebase shows 28 instances of SHA-1, 15 instances of prime256v1 ECDSA, and 18 instances of AES-128 scattered throughout production code paths. Modern applications, using contemporary build tools, are not escaping this; they are composing with it at the operating system level.

The solution is not to abandon OpenSSL, but to implement Crypto-Agility:

• Hybrid TLS Cipher Suites: Deploy certificates signed with both RSA-2048 (classical compatibility) and ML-DSA (quantum resistance). TLS 1.3 negotiates the strongest mutually supported algorithm at connection time.
• OpenSSL 3.0+ with FIPS Module: AWS-LC FIPS 3.0 (released December 2024) includes ML-KEM for key establishment. Organizations can begin deploying hybrid cipher suites immediately.
• Abstraction Layers: Encapsulate cryptographic operations (encryption, signing, hashing) behind APIs, allowing algorithm swaps without touching application code.

By May 2027, organizations should demonstrate (via CBOM + migration roadmap) that they have:

Inventoried OpenSSL dependencies across infrastructure

Evaluated hybrid cipher suite feasibility

Begun phased migration to ML-KEM + ML-DSA where feasible

Documented justification for any continued reliance on classical algorithms

The Data-at-Rest Trap: PostgreSQL pgcrypto and Long-Lived Encrypted Data

PostgreSQL's pgcrypto extension is trusted by thousands to encrypt sensitive fields (credit card PAN numbers, health records, biometric identities) before writing to disk. QScan audit revealed that pgcrypto's default configurations rely on Blowfish (1993), 3DES (1998), and SHA-1 (1995)—algorithms from the pre-9/11 era.​

A fintech company encrypting customer PAN numbers using pgcrypto's blowfish cipher in 2026 expects those columns to remain secure for the lifetime of the data—often 10, 20, or 30 years for financial records subject to regulatory retention requirements.

The data shelf-life problem is acute: Under HNDL, an attacker does not need to compromise the PostgreSQL server in 2026. They only need to:

Acquire a backup copy of the database file (from S3, from a data breach, from a careless export)

Store it indefinitely (negligible cost)

In 2030-2035, decrypt the entire historical database using Shor's algorithm

The encrypted backup containing 30 years of customer PAN numbers, health records, and personal details becomes transparently readable.

The DPDP Act Section 8(5) mandates "reasonable security safeguards" for data-at-rest. An organization relying on Blowfish encryption for PAN storage in 2026, when NIST-approved alternatives like AES-256 exist, and when re-encryption techniques are documented, is failing the reasonableness test.

Part V: Post-Quantum Cryptography Migration Roadmap for DPDP Act Compliance

Phase 0: Discovery & CBOM Generation

Objective: Establish baseline cryptographic posture; generate organization-wide CBOM inventory.

Activities:

Automated Cryptographic Discovery using QScan SAST to scan repositories (GitHub, GitLab, GitBucket, on-premises Git) for cryptographic patterns (RSA, ECC, Diffie-Hellman, MD5, SHA-1, 3DES, Blowfish).

CBOM Generation producing CycloneDX-compliant inventories for each service, microservice, library, and vendor dependency.

Risk Scoring assigning quantum risk levels based on algorithm type, key length, data sensitivity, and deployment environment.

Governance Alignment mapping cryptographic assets to business processes and regulatory obligations (payment processing, authentication, audit logging, PII storage).

Deliverables:

• Organization-wide CBOM dashboard (centralized view of all cryptographic assets)
• Risk-ranked inventory of quantum-vulnerable assets (prioritized for remediation)
• Data sensitivity mapping (which systems process Aadhaar, PAN, health data)
• Vendor cryptographic posture assessment (cloud providers, payment gateways, HSM vendors)

Phase 1: Standards Alignment & Pilot Deployment

Objective: Migrate critical systems to NIST post-quantum standards (FIPS 203-205).

Activities:

Hybrid TLS Deployment using NIST FIPS 203 (ML-KEM) for key establishment alongside classical RSA-based TLS. Configure web servers (NGINX, Apache, Envoy) to negotiate ML-KEM-hybrid cipher suites when both client and server support them, falling back to classical RSA for legacy clients.

ML-KEM Integration for microservices API authentication and inter-service key exchange. Implement parallel key agreement: both classical Diffie-Hellman and ML-KEM, accepting if either provides valid shared secret (cryptographically sound by NIST standards).

Data-at-Rest Encryption Review for PostgreSQL, DynamoDB, RDS, and custom encrypted databases. Develop re-encryption strategy:

• New records: AES-256 or ML-KEM-derived encryption
• Existing records: Rolling re-encryption with audit logging
• Backup strategy: Ensure encrypted backups support future quantum-safe decryption

Pilot Testing in development/staging environments. Benchmark ML-KEM performance (typically 10-30% CPU overhead compared to RSA; negligible for API latency). Test client/server version compatibility and fallback mechanisms.

Deliverables:

• Hybrid TLS certificates (dual-signed RSA-2048 + ML-DSA) deployed on public-facing services
• ML-KEM integration tested and performance-validated in non-production environments
• Data re-encryption strategy with automated key rotation policies
• Internal documentation of cryptographic upgrade procedures

Phase 2: Enterprise Hardening & Legacy Decommissioning

Objective: Achieve quantum-safe cryptography across internet-facing and high-sensitivity systems.

Activities:

Widespread Hybrid Deployment extending ML-KEM hybrid TLS to all customer-facing APIs, microservices, and internal service-to-service communication.

Hash Function Migration replacing MD5, SHA-1, and RIPEMD-160 with SHA-256, SHA-3, or eventually NIST-standardized post-quantum hash (SLH-DSA for signatures).

Certificate Authority (CA) Modernization issuing hybrid ML-DSA certificates for internal PKI, customer authentication, and code signing.

Legacy System Assessment identifying systems that cannot support hybrid cryptography (embedded systems, IoT devices, legacy hardware) and developing mitigations (encryption proxies, network segmentation, zero-trust access controls).

Vendor Contract Updates requiring third-party SaaS providers, payment processors, and cloud vendors to demonstrate quantum-safe cryptography roadmaps.

Deliverables:

• 80%+ of external APIs and microservices running hybrid ML-KEM TLS
• All hash functions migrated from MD5/SHA-1 to SHA-256 or NIST standards
• Internal CA issuing quantum-safe certificates
• Legacy system mitigation plan with timeline
• Vendor cryptographic attestations documented

Phase 3: Full Migration & Continuous Evolution

Objective: Transition to pure post-quantum cryptography; establish continuous cryptographic monitoring.

Activities:

Pure PQC Deployment as client/server adoption matures and classical algorithm support is deprecated.

Cryptographic Inventory Management via CI/CD integration: QScan automatically scans every source code commit, every dependency update, and every container image for quantum-vulnerable algorithms. Continuous compliance monitoring.

Vendor Engagement requiring SaaS providers to disclose quantum-readiness roadmaps; enforce contractual obligations for timely PQC migration.

Audit & Compliance Reporting producing quarterly CBOM updates and progress reports for the DPDP Data Protection Board, demonstrating continuous migration toward quantum-safe posture.

Part VI: Fintech & Indian Market Imperatives

India's Digital Finance Ecosystem at Risk

India's fintech sector is projected to reach ₹400,000+ crores ($50+ billion USD) by 2030. Yet this digital infrastructure is uniquely exposed to quantum and regulatory risk:​

Data Longevity: UPI processes billions of transactions monthly, with transaction records retained for 7-10 years (sometimes longer per RBI guidelines). Data encrypted with RSA-2048 in 2025 becomes quantum-vulnerable in 2030, 3 years into a 10-year retention window. The encrypted transaction logs become plaintext while still subject to regulatory safeguard requirements.

Fragmented Quantum Readiness: While large banks (ICICI, HDFC, SBI) are experimenting with quantum-safe pilots, much of the NBFC and fintech ecosystem remains unaware of HNDL and DPDP implications. A 2025 survey indicated 68% of Indian companies admit incomplete understanding of DPDP Act obligations.​

SEBI & RBI Regulatory Spotlight: In October 2025, SEBI's chairman explicitly stated that post-quantum cryptography is needed to protect capital markets. The RBI, banking regulator, has not yet issued formal quantum-safe guidelines—but regulatory silence should not be mistaken for permission. As DPDP Act enforcement escalates through 2027, regulators will increasingly expect quantum-readiness evidence.​

The Business Case for Immediate Action

For Indian fintech companies seeking funding, payment processor licenses, or banking partnerships:

• Quantum-safe cryptography readiness is becoming a due diligence requirement
• Investors will demand CBOMs and migration roadmaps as proof of technical soundness
• Regulatory approval for payment processing will increasingly require quantum-safe attestations

The 24-month window from January 2026 to May 2027 is the critical intervention period. Organizations that begin Phase 1 (CBOM discovery) immediately will have documented migration plans by DPDP Phase 3 enforcement. Organizations delaying action until late 2026 will face rushed implementations, vendor backlogs, and regulatory non-compliance.

Conclusion: From Complacency to Accountability

The quantum cryptographic debt crisis is not a 2035 concern. It is a present regulatory liability (DPDP Act enforcement May 2027) converging with a near-term technical threat (Shor's algorithm breakable RSA by 2030) and an active adversarial campaign (HNDL attacks harvesting encrypted data today).

The evidence is irrefutable:

• QScan audits document 596-1,138 quantum-vulnerable cryptographic assets across enterprise stacks (OpenSSL, Node.js, PostgreSQL, WordPress).
• NIST FIPS 203-205 standards are operationally available (August 2024), with vendor implementations (AWS-LC FIPS 3.0, open-source libpqcrypto, commercial cryptographic modules).
• DPDP Act enforcement begins May 2027 with penalties reaching ₹250 crores for organizations failing to implement "reasonable security safeguards"—now defined to include quantum-resistant cryptography when standards are available.
• Data shelf-life problem is acute: Encrypted personal data (Aadhaar, PAN, health records) with 10-30 year retention obligations becomes permanently exposed if encrypted with pre-2027 classical algorithms.

Organizations that continue deploying RSA-2048, ECDSA, and MD5 in 2026-2027, after NIST standards are available and after the DPDP Act enforcement date has been publicly announced, are making a documented choice to maintain quantum-vulnerable cryptography. Under Indian administrative and tort law, this constitutes negligence, converting quantum vulnerability into a present compliance liability.

The path forward is not disruptive. Hybrid cryptography and crypto-agility enable classical-compatible TLS while simultaneously supporting quantum-safe key establishment. Organizations implementing Phase 1 (hybrid deployment) before May 2027 will demonstrate "reasonable security safeguards" to the DPDP Board and establish a foundation for complete migration by 2035.
