Cryptographic Analysis

When to Activate

  • Auditing TLS/SSL/SSH configurations and X.509 PKI (cipher suites, downgrade, protocol flaws)
  • Reviewing crypto implementations in source code or captured traffic
  • Attacking weak RSA/ECC keys (CTF and real-world weak-key hygiene)
  • Recovering ECDSA/DSA private keys from reused or biased nonces (lattice/HNP)
  • Exploiting symmetric/AEAD misuse: padding oracles, GCM nonce reuse, key-commitment
  • Forging JWT/JOSE tokens (algorithm confusion, none, jwk/jku/kid injection)
  • Cracking password hashes and grading KDF strength
  • Assessing post-quantum readiness ("harvest now, decrypt later" exposure)
