CryptCheck needs support of old, unsecured and so deprecated protocols (SSLv2, SSLv3…) or cipher suite (RC4, 3DES…) to be able to fully cover SSL/TLS verifications.
OpenSSL 1.0 is necessary to support such deprecated things, but new TLS features like TLSv1.3 requires 1.2. And currently, Ruby is tied to a single OpenSSL binding, only old Ruby version (2.3) supports OpenSSL 1.0 and at the opposite, only 2.5+ supports 1.2.
It will be a real mess to use multiple binding to fully check a server
- multiple OpenSSL bindings
- multiple Ruby versions
- RPC or equivalent
- not totally ordered set for server preferences
This project is a SSL/TLS pure Ruby implementation to remove CryptCheck OpenSSL dependency and so to support together old and new SSL/TLS features.

This is not a cryptographic safe implementation!
