implement enough glue to support OpenSSLs EVP, RSA, DSA, DH, HMAC and ENGINE interfaces for use in hx509. rename all symbols to start with hc_ to avoid clobbering namespaces. contains no RSA/DH/DSA code, just glue to support using dynamic ENGINE. hx509 supports this via pkcs11 and there is a gmp ENGINE module supporting RSA
