🚀 Try it now: Migrate your first key in 10 minutes

Quick Start: Migrate Your First Key

Estimated time: 10 minutes What you'll do: Import an RSA key, analyze it, and convert encrypted data to ML-KEM Requirements: AnkaSecure API access, existing RSA encrypted file

Step 1/4: Import your existing RSA key (2 minutes)

# Import from PKCS#12 keystore
curl -X POST https://api.ankatech.co/migration/import/pkcs12 \
  -H "Authorization: Bearer $TOKEN" \
  -F "[email protected]" \
  -F "password=myP4ssword" \
  -F "tenantId=your-tenant-id"

✅ Success: You'll receive a keyId for your imported key:

{
  "keyId": "legacy-rsa-001",
  "algorithm": "RSA_2048",
  "status": "ACTIVE",
  "imported": "2026-01-07T10:30:00Z"
}

❌ Common error: "Invalid keystore password" - Double-check your .p12 password

Step 2/4: Analyze compatibility (1 minute)

# Check if your key can migrate to PQC
curl -X POST https://api.ankatech.co/migration/analyze \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "keyId": "legacy-rsa-001",
    "targetAlgorithm": "ML_KEM_1024"
  }'

✅ Success: Compatibility report shows migration path:

{
  "compatible": true,
  "recommendedAlgorithm": "ML_KEM_1024",
  "securityLevel": "EQUIVALENT",
  "estimatedConversionTime": "< 1 second per MB"
}

Step 3/4: Generate PQC key (1 minute)

# Create your new quantum-resistant key
curl -X POST https://api.ankatech.co/keys \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "algorithm": "ML_KEM_1024",
    "keyPurpose": "DATA_ENCRYPTION"
  }'

✅ New keyId: pqc-mlkem-001

Step 4/4: Re-encrypt data (5 minutes for 100 files)

# Convert RSA-encrypted file to ML-KEM
curl -X POST https://api.ankatech.co/migration/convert/re-encrypt \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "sourceKeyId": "legacy-rsa-001",
    "targetKeyId": "pqc-mlkem-001",
    "ciphertextFile": "encrypted-with-rsa.dat"
  }'

✅ Success: Your data is now quantum-resistant! Original file replaced.

Why Migrate to Post-Quantum Cryptography Now?

The $840K Cost Avoidance Story

Real scenario: Enterprise with 200 applications using RSA/ECDSA encryption

Approach	Time	Cost	Risk
Traditional (rewrite apps)	6-12 months	$840,000	Extremely high
ANKASecure (API-driven)	1 day	$30	Minimal

Cost reduction: 99.99% savings

How it works: - ❌ Traditional: Rewrite crypto logic in 200 apps (70 hours per app @ $60/hour) - ✅ ANKASecure: Update configuration once, all apps use new algorithm automatically (30 minutes)

The Quantum Timeline: Why Now?

Regulatory deadlines: - 2024: NIST publishes final PQC standards (ML-KEM, ML-DSA, SLH-DSA) - 2025: White House Executive Order 14144 mandates PQC transition - 2030: NSA deadline (CNSA 2.0) - quantum-resistant algorithms required for classified data

Security threat: "Harvest now, decrypt later" attacks - Adversaries capture encrypted data TODAY - Decrypt when quantum computers arrive (estimated 2030-2035) - If your data must stay confidential beyond 2030, migrate NOW

Who needs PQC today? - Financial services (transaction records, trading data) - Healthcare (patient records with 20+ year retention) - Government (classified documents) - Legal (contracts, intellectual property)

The AnkaSecure Migration Advantage

1. Zero-Code Migration

Traditional migration:

// Before: App code directly calls crypto library
RSACipher cipher = new RSACipher();
byte[] encrypted = cipher.encrypt(data, rsaKey);

// After: Must rewrite app to use ML-KEM
MLKEMCipher cipher = new MLKEMCipher();  // ❌ Code change required!
byte[] encrypted = cipher.encrypt(data, mlkemKey);

ANKASecure migration:

// App code NEVER changes - keyId stays the same
AnkaSecure.encrypt(data, keyId);  // ✅ Algorithm change is transparent!

Benefit: Update algorithm in ANKASecure config → all apps instantly use ML-KEM

2. Crypto-Agility: Instant Algorithm Updates

# Example: Switch all apps from RSA to ML-KEM with ONE API call
curl -X PATCH https://api.ankatech.co/keys/legacy-rsa-001 \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "migrateTo": "ML_KEM_1024",
    "strategy": "IMMEDIATE"  # or GRADUAL for phased rollout
  }'

Result: All apps using legacy-rsa-001 now encrypt with ML-KEM (decryption still supports RSA for existing data)

3. Data Re-Encryption Without Plaintext Exposure

The problem with traditional re-encryption:

Traditional: Ciphertext → Decrypt to plaintext → Re-encrypt with new key
              ↑                                         ↓
         Security risk!                          Network exposure!

ANKASecure's solution: Direct ciphertext transformation (no plaintext ever exists)

AnkaSecure: RSA ciphertext → ML-KEM ciphertext (server-side transformation)
                          ↑
                  Zero plaintext exposure!

Security benefit: Plaintext never leaves AnkaSecure's secure cryptographic boundary

Migration Strategies

Strategy 1: Phased Migration (Recommended for Production)

Timeline: 3-6 months Risk: Low Best for: Large enterprises with 100+ applications

Phases: 1. Pilot (2-4 weeks): Migrate 1-2 non-critical apps 2. Gradual rollout (2-3 months): Migrate 10% of apps per week 3. Full production (1 month): Complete migration, monitor performance 4. Classical decommission (ongoing): Archive old RSA keys after data expiration

Example workflow:

# Week 1: Import all RSA keys
for key in keys/*.p12; do
  ankaSecure import "$key"
done

# Weeks 2-12: Migrate 20 apps per week (10% of 200 apps)
ankaSecure migrate --apps batch1.txt --strategy PHASED --weeks 12

# Month 4: Validate all data accessible
ankaSecure validate --all-apps

Strategy 2: Hybrid Dual-Algorithm (Zero-Risk Transition)

Timeline: 1-2 months Risk: Very Low Best for: High-security environments (finance, government, healthcare)

How it works: Composite hybrid keys combine RSA + ML-KEM - Data encrypted with BOTH algorithms simultaneously - Decryption requires BOTH keys (1000× more secure than OR-decrypt) - Instant rollback if PQC vulnerability discovered (fallback to RSA only)

Example:

# Generate composite key (RSA + ML-KEM)
curl -X POST https://api.ankatech.co/keys/composite \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "classicalAlgorithm": "RSA_4096",
    "pqcAlgorithm": "ML_KEM_1024",
    "mode": "HYBRID_KEM_COMBINE"  # AND-decrypt semantics
  }'

Compliance: NIST SP 800-208 compliant (federal procurement ready)

Strategy 3: Direct Cutover (Fast-Track for New Systems)

Timeline: 1-2 weeks Risk: Medium Best for: Greenfield projects, isolated systems, dev/test environments

Steps: 1. Create ML-KEM keys for all apps (1 day) 2. Update app configs to use new keyIds (1 day) 3. Deploy updated configs (1 day) 4. Validate encryption/decryption (2-3 days) 5. Monitor production (ongoing)

No data re-encryption needed (only for new data going forward)

Migration Capabilities

1. Import: Bring Legacy Keys into AnkaSecure

Supported formats: - PKCS#12 (.p12, .pfx) - Windows certificates, Java keystores - X.509 certificates (.crt, .pem) - JKS keystores (Java) - Azure Key Vault export - AWS KMS external keys (via public key)

Validation pipeline (7 stages): 1. Structure validation (X.509 ASN.1 format) 2. Key binding verification 3. Temporal validity (not before/not after) 4. Certificate chain validation 5. Trust anchor verification (RFC 5280) 6. Revocation checking (OCSP, CRL) 7. Security analysis (algorithm strength, expiration risk)

Security: All imported keys wrapped with HSM KEK (Key Encryption Key)

Example: Import from AWS KMS:

# Step 1: Export public key from AWS KMS
aws kms get-public-key --key-id alias/my-rsa-key > aws-public.pem

# Step 2: Import to AnkaSecure
curl -X POST https://api.ankatech.co/migration/import/public-key \
  -H "Authorization: Bearer $TOKEN" \
  -F "[email protected]" \
  -F "sourceSystem=AWS_KMS"

Use cases: - Migrating from legacy CAs (VeriSign, DigiCert, internal PKI) - Consolidating keys from multiple systems (Azure, AWS, on-premise) - Recovering keys from backup keystores - Importing TLS/SSL certificates for renewal

2. Analyze: Validate Compatibility Before Migration

Analysis types: - Certificate validation: X.509 structure, chain verification, expiration checks - Compatibility analysis: Can RSA-2048 migrate to ML-KEM-1024? (YES - equivalent security level) - Security analysis: Weak algorithms detected? (e.g., MD5 signatures) - Compliance checking: FIPS 140-2 compliant? CNSA 2.0 ready?

Example output:

{
  "keyId": "legacy-rsa-001",
  "algorithm": "RSA_2048",
  "status": "ACTIVE",
  "securityLevel": "NIST_LEVEL_3",
  "migrationPath": {
    "recommendedAlgorithm": "ML_KEM_1024",
    "securityEquivalence": "EQUIVALENT",
    "estimatedPerformanceImpact": "+15% latency",
    "blockingIssues": []
  },
  "complianceStatus": {
    "FIPS_140_2": true,
    "CNSA_2_0": false,  // RSA not quantum-resistant
    "NIST_PQC": false
  }
}

Automated recommendation: Suggests ML-KEM-1024 for RSA-2048 (equivalent 192-bit security level)

3. Convert: Transform Encrypted Data and Signatures

Conversion operations: - Re-encrypt: RSA ciphertext → ML-KEM ciphertext (no plaintext exposure) - Re-sign: RSA signature → ML-DSA signature (preserves document integrity) - Batch conversion: Process 1000s of files in parallel - Streaming conversion: Multi-GB files without memory overflow

Example: Bulk re-encrypt 1000 files:

# Create batch job
curl -X POST https://api.ankatech.co/migration/batch/re-encrypt \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "sourceKeyId": "legacy-rsa-001",
    "targetKeyId": "pqc-mlkem-001",
    "fileList": [
      "s3://mybucket/encrypted/*.dat",  // S3 wildcard
      "/mnt/legacy/archives/*.enc"      // Local filesystem
    ],
    "parallelism": 10  // 10 concurrent conversions
  }'

Output: Job ID for monitoring progress

# Check progress
curl https://api.ankatech.co/migration/batch/job-12345/status \
  -H "Authorization: Bearer $TOKEN"

Performance: ~100 files/minute (1KB each, RSA-2048 → ML-KEM-1024)

4. Interoperability: Bridge Legacy and PQC Systems

Problem: Legacy systems can't decrypt ML-KEM ciphertext during migration

Solution: AnkaSecure acts as cryptographic bridge

Bridge pattern:

Legacy App (RSA-only)  ←→  AnkaSecure Bridge  ←→  PQC System (ML-KEM)
                           ↑
                    Transparent translation

Example workflow: 1. PQC system encrypts data with ML-KEM 2. Legacy app requests decryption from AnkaSecure 3. AnkaSecure decrypts ML-KEM → returns plaintext (over TLS) 4. Legacy app processes plaintext (no code changes!)

Use case: Gradual migration where not all apps can upgrade immediately

Security note: Plaintext only exists in TLS-encrypted channel (mTLS recommended)

Enterprise Migration Roadmap

Phase 1: Assessment (1-2 weeks)

Deliverables: - Inventory of all cryptographic keys (RSA, ECDSA, etc.) - Application dependency map (which apps use which keys) - Data sensitivity classification (public, internal, confidential, secret) - Regulatory requirements (FIPS, CNSA 2.0, industry-specific)

Tools: - 📥 Download: Migration Assessment Template - 🔍 Automated key discovery tool (scans filesystems, databases, cloud vaults)

Phase 2: Pilot (2-4 weeks)

Goal: Validate ANKASecure in isolated environment

Steps: 1. Deploy AnkaSecure in non-production environment 2. Import keys from 1-2 low-risk applications 3. Test encrypt/decrypt workflows 4. Measure performance (latency, throughput) 5. Validate monitoring/alerting

Success criteria: - Zero data loss - < 20% performance degradation - All test cases pass

Phase 3: Production Rollout (2-3 months)

Strategy: Phased migration (10% of apps per week)

Week-by-week plan: - Week 1-2: Migrate 10% of apps (lowest risk) - Week 3-4: Migrate 20% (monitor error rates) - Week 5-8: Migrate 60% (production workloads) - Week 9-12: Migrate remaining 10% (highest risk apps)

Monitoring: Real-time dashboards for: - Encryption/decryption success rates - API latency (p50, p95, p99) - Error rates by application - Key usage analytics

Phase 4: Validation (1 month)

Verification steps: - Decrypt sample data from all apps (spot checks) - Performance regression testing - Security audit (no weak algorithms in use) - Compliance verification (CNSA 2.0 checklist)

Sign-off: CTO, CISO, Compliance Officer approval

Phase 5: Classical Decommission (Ongoing)

Timeline: 6-12 months after full migration (allow for data expiration)

Steps: 1. Archive RSA keys (do NOT delete - needed for old backups) 2. Rotate all keys to pure PQC (no hybrid mode) 3. Update disaster recovery procedures 4. Document new key management processes

Compliance: Maintain audit trail for regulatory requirements
