The Open Source Technology Improvement Fund, Inc, thanks to funding provided by Sovereign Tech Fund, engaged with Quarkslab to perform a security audit of PHP-SRC, the interpreter of the PHP language.

Following the introduction of crypto-condor and differential fuzzing in earlier blogposts, we showcase a use case where Quarsklab's automated test suite for cryptographic implementations allowed us to improve the reference implementation of the recently standardized HQC scheme.

In this blog post we present crypto-condor, an open-source test suite for compliance testing of implementations of cryptographic primitives.
