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.
