Themis development security practices # Our approach to testing Themis: Every Themis PR is checked with CircleCI, Bitrise, and GitHub Actions, which run a set of tests on the whole code base across 13 languages. Every major Themis release is tested by our internal systems, by building it on a number of platforms (including intentionally broken builds with wrong parameters). Every time some new security-related features are introduced to Themis, they undergo a brief 3rd-party code review.
