            "content": "The OpenSSL base provider supplies the encoding for OpenSSL's\nasymmetric cryptography.\n\nProperties\nThe implementations in this provider specifically have this property\ndefined:\n\n\"provider=base\"\n\nIt may be used in a property query string with fetching functions.\n\nIt isn't mandatory to query for this property, except to make sure to\nget implementations of this provider and none other.\n\n\"type=parameters\"\n\"type=private\"\n\"type=public\"\n\nThese may be used in a property query string with fetching functions to\nselect which data are to be encoded.  Either the private key material,\nthe public key material or the domain parameters can be selected.\n\n\"format=der\"\n\"format=pem\"\n\"format=text\"\n\nThese may be used in a property query string with fetching functions to\nselect the encoding output format.  Either the DER, PEM and plaintext\nare currently permitted.\n",
