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.
