6. Use Cases
6.1 Blockchain & Web3
Problem: Most blockchain protocols use ECDSA/EdDSA, vulnerable to quantum attacks
Solution: Cryptic provides post-quantum signing for:
Transaction signing
Multi-sig wallets
Smart contract deployment
Cross-chain bridges
Case Study: Filecoin
Use Case: Quantum-resistant storage proofs
Implementation: Dilithium3 signatures for proof-of-spacetime
Benefits: Future-proof against quantum attacks on storage network
Integration Pattern:
User authenticates with existing wallet (chain signature)
Generate PQC key pair in Cryptic
Dual-sign transactions: Traditional (ECDSA) + PQC (Dilithium3)
Blockchain validates both signatures
Gradual transition as ecosystem adopts PQC
6.2 Certificate Authorities
Problem: X.509 certificates will need post-quantum signatures
Solution: Cryptic CA integration
Generate PQC root and intermediate certificates
Sign certificate requests with Dilithium3
Hybrid classical/PQC certificate chains during transition
6.3 Secure Messaging
Problem: Signal, WhatsApp use ECDH - quantum vulnerable
Solution: Kyber768 for key exchange
Post-quantum key encapsulation
Forward secrecy
Hybrid X25519 + Kyber768 during transition
6.4 Document Signing
Problem: PDF signatures, code signing uses RSA/ECDSA
Solution: Dilithium3 signatures
Legal document signing
Software package signing
Notarization services
6.5 IoT & Edge Computing
Problem: IoT devices lack resources for PQC
Solution: Cryptic as crypto accelerator
Offload PQC operations to TEE
Lightweight client SDK
Session-based authentication
