§ ECC_initialize()

void ECC_initialize ( ECC_State *  state,

Initialize elliptic curve parameters to default values and specify workzone.

This function initializes the elliptic curve parameters to default values. The default elliptic curve used is NIST-P256.

The workzone defaults to an expected window size of 3.

This function can be called again to point the ECC workzone at a different memory buffer.

Parameters
