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
                   Returned pointer to newly allocated output array.

       size_t * saltlen
                   Pointer to integer, returning size of output array.

DESCRIPTION

       Computes 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 provided by asrep, and if
       present returns it.  Otherwise the salt is composed  from  the  client  name  and  the  realm,  both  are
       extracted from the request asreq.

RETURN VALUE

       Returns SHISHI_OK if successful.  Failure conditions include various ASN.1 issues.
