Project Wycheproof is a collection of JSON test vectors for testing cryptography libraries against known attacks, specification inconsistencies, and implementation bugs. It covers popular algorithms including AES-GCM, ECDSA, RSA, EdDSA, and post-quantum schemes like ML-KEM and ML-DSA.

Use cases

• test my crypto library against known attacks
• find edge cases in ECDSA signature verification
• check for Bleichenbacher padding oracle vulnerabilities
• validate post-quantum algorithm implementations like ML-KEM
• add cryptographic test vectors to CI
• detect invalid curve attacks in ECDH
• verify AEAD implementations like AES-GCM and ChaCha20-Poly1305

When to choose

• you are developing or maintaining a cryptography library and want to catch known attack classes
• you want curated, schema-documented test vectors covering 80+ attack cases across many algorithms
• you need to test post-quantum primitives like ML-KEM and ML-DSA

When to avoid

• you need a runnable test suite rather than raw test vector data to integrate yourself
• you need functional crypto primitives rather than tests for them
• you need fuzzing or dynamic analysis rather than fixed known-answer and attack vectors
