Working with cryptographic libraries is hard, and a single implementation mistake can result in . To help developers check their code for implementation errors and find weaknesses in cryptographic software libraries, Google has released a test suite as part of .

“In cryptography, subtle mistakes can have catastrophic consequences, and mistakes in open source cryptographic software libraries repeat too often and remain undiscovered for too long,” Google security engineers Daniel Bleichenbacher and Thai Duong, wrote in a post announcing the project on the .

Named after Australia’s Mount Wycheproof, the world’s smallest mountain, Wycheproof provides developers with a collection of unit tests that detect known weaknesses in cryptographic algorithms and check for expected behaviors. The first set of tests is written in Java because Java has a common cryptographic interface and can be used to test multiple providers.

“We recognize that software engineers fix and prevent bugs with unit testing, and we found that many cryptographic issues can be resolved by the same means,” Bleichenbacker and Duong wrote.

, all the code for Wycheproof is available on GitHub. OSS-Fuzz is still in beta, but it has already worked through 4 trillion test cases and uncovered 150 bugs in open source projects since it was publicly announced.
