EVP_PBE_CipherInit_ex() also allows the application to specify a library context libctx and property query propq to select appropriate algorithm implementations.
1. An algorithm type type which can be:
2. A pbe_nid which can represent the algorithm identifier with parameters e.g. NID_pbeWithSHA1AndRC2_CBC or an algorithm class e.g. NID_pbes2.
They return the algorithm's cipher ID pcnid, digest ID pmnid and a key generation function for the algorithm pkeygen. EVP_PBE_CipherInit_ex() also returns an extended key generation function keygen_ex which takes a library context and property query.
If a NULL is supplied for any of pcnid, pmnid, pkeygen or pkeygen_ex then this parameter is not returned.
