If, for some reason, you believe that an important security problem we're facing is an insufficient number of available algorithms, you can study how these recent algorithms are integrated into OpenSSL generally, X.509, CMS and TLS, and integrate your algorithms in a similar manner. You might also take a look at the OpenSSL master (3.0) development branch, which introduces changes to the internal architecture that are intended to better facilitate integration of external cryptographic modules. -- Viktor.
