\brief This function performs the following math “r = (a^p) % m”.
|
|
|
|
\return SSL_SUCCESS On successfully performing math operation.
|
|
\return SSL_FAILURE If an error case was encountered.
|
|
|
|
\param r structure to hold result.
|
|
\param a value to be raised by a power.
|
|
\param p power to raise a by.
|
|
\param m modulus to use.
|
|
\param ctx currently not used with wolfSSL can be NULL.
|
|
|
|
_Example_
|
|
\code
|
|
WOLFSSL_BIGNUM r,a,p,m;
|
|
int ret;
|
|
// set big number values
|
|
ret = wolfSSL_BN_mod_exp(r, a, p, m, NULL);
|
|
// check ret value
|
|
\endcode
