Overview
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.
