Crypto Technique
Goal: help the agent diagnose cryptographic weaknesses, select the right attack, and execute exploitation to recover secrets—keys, plaintexts, random state, or authentication bypasses.
When this technique applies
- Encrypted data with weak or custom cipher implementation.
- Public cryptographic key material (RSA, ECC, DSA) with non-standard properties.
- Oracle-based systems: padding oracles, timing leaks, signature verification errors.
- Pseudo-random number generators with biased output or insufficient entropy.
- Symmetric cipher misuse: ECB mode, IV reuse, weak key derivation.
- Ransomware or malware encryption routines requiring algorithm, key hierarchy, and recovery-feasibility analysis.
- Mathematical shortcuts: incomplete prime checking, careless modulus construction, protocol design flaws.
