The OpenSSL base provider supplies the encoding for OpenSSL's asymmetric cryptography. Properties The implementations in this provider specifically have this property defined: "provider=base" It may be used in a property query string with fetching functions. It isn't mandatory to query for this property, except to make sure to get implementations of this provider and none other. "type=parameters" "type=private" "type=public" These may be used in a property query string with fetching functions to select which data are to be encoded. Either the private key material, the public key material or the domain parameters can be selected. "format=der" "format=pem" "format=text" These may be used in a property query string with fetching functions to select the encoding output format. Either the DER, PEM and plaintext are currently permitted.

This functionality was added in OpenSSL 3.0. Support for ML-DSA and <ML-KEM> was added in OpenSSL 3.5.
