Expand description

1024-bit RSA PSS SHA-256 sign with CRT acceleration.

The message * m - is signed and the signature returned in * s - .

  • s - The generated 128-byte signature.
  • m - The message to be signed.
  • m_len - Length of * m - .
  • salt - The salt to be used.
  • s_len - Length of * salt - .
  • sk - A valid 1024-bit RSA secret key with CRT coefficients.

Returns -2 If the salt is too long. Returns 0 On success.

@remark The key * sk - should be initialized with * ocrypto_rsa1024_init_crt_key - . @remark * s - may be same as * m - .
