shishi_as_derive_salt - API function

SYNOPSIS

#include <shishi.h>

int shishi_as_derive_salt(Shishi * handle, Shishi_asn1 asreq, Shishi_asn1 asrep, char ** salt, size_t * saltlen);

ARGUMENTS

Shishi * handle: shishi handle as allocated by shishi_init().
Shishi_asn1 asreq: input AS-REQ variable.
Shishi_asn1 asrep: input AS-REP variable.
char ** salt: newly allocated output array with salt.
