Expand description
RSA secret key setup with CRT coefficients.
key
- The initialized secret key.key_mem
- Key memory. Length OCRYPTO_RSA_CRT_KEY_SIZE(bits). Must have same lifetime as *key
- .p
- The 1. RSA prime, unsigned big-endian.p_len
- Length of *p
- .q
- The 2. RSA prime, unsigned big-endian.q_len
- Length of *q
- . Must be same as *p_len
- .dp
- The 1. CRT exponent, dp = d mod (p-1), unsigned big-endian.dp_len
- Length of *dp
- .dq
- The 2. CRT exponent, dq = d mod (q-1), unsigned big-endian.dq_len
- Length of *dq
- .qinv
- The CRT coefficient, qinv = 1/q mod p, unsigned big-endian.qi_len
- Length of *qinv
- .
Returns -1 If the input length is invalid. Returns 0 On success.
@remark The p, q, dp, dq, and qinv values can be read directly from a DER encoded RSAPrivateKey.
