Crypto Analysis

This is your cryptographic assessment toolkit for pentesting and security research. It covers the full spectrum: identifying hash types and cipher modes, auditing TLS configurations with testssl and openssl, cracking passwords with hashcat and john, and reviewing crypto implementations for common pitfalls like ECB mode, static IVs, and missing authentication. The real value is in the implementation review guidance, it flags dangerous patterns like predictable randomness and walks through actual attack implementations including padding oracles and ECDSA nonce reuse recovery. Also includes RSA-CTF-Tool integration and side-channel detection patterns. Useful during recon when you find hashes or certificates, and before exploitation when you need to understand if crypto weakness is your entry point.
