Ummm... I'm not entirely sure. At some point, I need to look at implementing the rxgk security class to allow gss to be used. That can in theory support any kerberos cipher suite (which don't include pcbc or fcrypt). I don't yet know how much code I could theoretically share with rxkad.c. However, since pcbc and fcrypt are only used by rxkad.c, it might make sense to move them to net/rxrpc/ and hard code them in rxkad.c - though I'd prefer to make an attempt on rxgk first. David
