Expand description

2048-bit RSA PKCS1 V1.5 SHA-256 sign with CRT acceleration.

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

  • s - The generated 256-byte signature.
  • m - The message to be signed.
  • mlen - Length of * m - .
  • sk - A valid 2048-bit RSA secret key with CRT coefficients.

Returns 0

@remark The key * sk - should be initialized with * ocrypto_rsa2048_init_crt_key - . @remark * s - may be same as * m - .
