Expand description

RSA PSS SHA-256 sign with CRT acceleration.

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

  • s - The generated signature.
  • s_len - Length of * m - .
  • m - The message to be signed.
  • m_len - Length of * m - .
  • salt - The salt to be used.
  • salt_len - Length of * salt - .
  • key - A valid RSA secret key with CRT coefficients.
  • mem - The working memory. Length OCRYPTO_RSA_CRT_MEM_SIZE(bits).

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

@remark The key * key - should be initialized with * ocrypto_rsa_init_crt_key - . @remark * s - , * m - , and * mem - may be same.
