The ideal function would basically tell me which PEM_read_bio_foobar function I would use to read the PEM data (and thus what C type it represents). It would lump all private key formats into one type, since PEM_read_PrivateKey would work on all of them and return an EVP_PKEY. > > Does such a function already exist? Any thoughts? PEM_read_bio() reads a generic PEM object. The header name can then be compared with the various PEM_STRING_... constants. OpenSSL can already read keys in a general way. See, PEM_read_bio_PrivateKey() returning an EVP_PKEY. So you don't need to reinvent this. -- Viktor. -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
