Mostly because the "human-readable" descriptions are a rather
unstable interface. I believe that for some exotic signature
schemes they return a multi-line description of the algorithm and
parameters! The C code to get the signature description inside
OpenSSL itself is as you point out rather complex, and dives
deep into library internals. I think you should ask for
guidance on openssl-users, I don't know the answer to this,
beyond the observation that it is easy if you 'settle' for
an OID.
