ECDSA_sign_p1363 function

@RecordUse.new() @Native<Int Function(Pointer<Uint8>, Size, Pointer<Uint8>, Pointer<Size>, Size, Pointer<EC_KEY>)>(ffi.Pointer<ffi.Uint8>, ffi.Size, ffi.Pointer<ffi.Uint8>, ffi.Pointer<ffi.Size>, ffi.Size, ffi.Pointer<EC_KEY>)>(symbol: 'bssl_dart_ECDSA_sign_p1363') int ECDSA_sign_p1363(Pointer<Uint8> digest, int digest_len, Pointer<Uint8> sig, Pointer<Size> out_sig_len, int max_sig_len, Pointer<EC_KEY> key,)

ECDSA_sign_p1363 signs digest_len bytes from digest with key and writes the resulting P1363-based signature to sig, which must have ECDSA_size_p1363(key) bytes of space. On successful exit, *out_sig_len is set to the actual number of bytes written, which will always match ECDSA_size_p1363(key). It returns one on success and zero otherwise.

WARNING: digest must be the output of some hash function on the data to be signed. Passing unhashed inputs will not result in a secure signature scheme.
