EVP_DigestSign function

  1. @RecordUse.new()
  2. @Native<Int Function(Pointer<EVP_MD_CTX>, Pointer<Uint8>, Pointer<Size>, Pointer<Uint8>, Size)>(ffi.Pointer<EVP_MD_CTX>, ffi.Pointer<ffi.Uint8>, ffi.Pointer<ffi.Size>, ffi.Pointer<ffi.Uint8>, ffi.Size)>(symbol: 'bssl_dart_EVP_DigestSign')
int EVP_DigestSign(
  1. Pointer<EVP_MD_CTX> ctx,
  2. Pointer<Uint8> out_sig,
  3. Pointer<Size> out_sig_len,
  4. Pointer<Uint8> data,
  5. int data_len,
)

EVP_DigestSign signs |data_len| bytes from |data| using |ctx|. If |out_sig| is NULL then |*out_sig_len| is set to the maximum number of output bytes. Otherwise, on entry, |*out_sig_len| must contain the length of the |out_sig| buffer. If the call is successful, the signature is written to |out_sig| and |*out_sig_len| is set to its length.

It returns one on success and zero on error.
