wycheproof

Comprehensive test vectors for validating cryptographic implementations against known attacks and edge cases. 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. Cryptographic implementations are notoriously difficult to get right. Even small bugs can: Wycheproof has found vulnerabilities in major libraries including OpenJDK's SHA1withDSA, Bouncy Castle's ECDHC, and the elliptic npm package. Apply Wycheproof when: Consider alternatives when: The Wycheproof repository is organized as follows: The essential folders are testvectors and testvectors_v1 . While both contain similar files, testvectors_v1 includes more detailed information and is recommended for new integrations. Wycheproof provides test vectors for a wide range of cryptographic algorithms: Each JSON test file tests a specific cryptographic construction.
