Expand description

RSA secret key setup.

  • key - The initialized secret key.
  • key_mem - Key memory. Length OCRYPTO_RSA_PUB_KEY_SIZE(bits). Must have same lifetime as * key - .
  • n - The RSA modulus, unsigned big-endian.
  • n_len - Length of * n - .
  • d - The secret exponent, unsigned big-endian.
  • d_len - Length of * d - . Must be <= * n_len - .

Returns -1 If the input length is invalid. Returns 0 On success.

@remark The n and d values can be read directly from a DER encoded RSAPrivateKey.
