NAME

       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.

       size_t * saltlen
		   holds actual size of output array with salt.

DESCRIPTION

       Derive the salt that should be used when deriving a key via shishi_string_to_key() for an AS exchange.  Currently this searches for PA-DATA
       of type SHISHI_PA_PW_SALT in the AS-REP and returns it if found, otherwise the salt is derived from the client name and realm in AS-REQ.

RETURN VALUE

       Returns SHISHI_OK iff successful.
