Wycheproof

Wycheproof is an extensive collection of test vectors designed to verify the correctness of cryptographic implementations and test against known attacks. Originally developed by Google, it is now a community-managed project where contributors can add test vectors for specific cryptographic constructions.

Background

Key Concepts

Concept Description
Test vector Input/output pair for validating crypto implementation correctness
Test group Collection of test vectors sharing attributes (key size, IV size, curve)
Result flag Indicates if test should pass (valid), fail (invalid), or is acceptable
Edge case testing Testing for known vulnerabilities and attack patterns
