Don't trust CAIN-42. Verify CAIN-42. This is the Independent Human Verification Resource Kit for Crypto Audit: every claim its page makes, as the exact request and the answer it must give, recorded live and signed. You check it on your own machine with a short Python script that uses no CAIN-42 code.

Every claim matched when recorded

Verify it on your own machine

unzip cain42-ihvrk-crypto-audit.zip && cd cain42-ihvrk-crypto-audit
python3 verify.py            # offline: hashes, Ed25519 signature, recorded answers
python3 verify.py --live     # also re-send every request yourself and check the answers now

A claim that cannot be checked counts as a FAIL, never a pass. The live check is the one that depends on nothing we recorded.

The claims in this kit

#ClaimAnswer must contain
C01Modern code: bcrypt, SHA-256, secrets, default TLS -> No findings: no false alarm.[0]
C02Signature check off, TLS check off, key in the code -> Three classic mistakes, three findings.[3]
C03Passwords hashed with MD5 -> MD5 is broken for passwords.["WeakHash_MD5"]
C04AES in ECB mode -> ECB leaks patterns in the data.["InsecureMode_ECB"]
C05random() used for a security token -> random() is predictable; use secrets.["InsecureRandom_Crypto"]
C06A 1024-bit RSA key -> Under 2048 bits is too short.["ShortRSAKey"]

What this kit is, and is not

It shows what the live product answered to these inputs, and lets anyone check that again. It is not a third-party audit, a certification, or a promise about inputs not listed. The product's limits page lists what it does not do.
