    abstract =  {This document defines the Pseudo-Random Function (PRF) for the Kerberos V mechanism for the Generic Security Service Application Program Interface (GSS-API), based on the PRF defined for the Kerberos V cryptographic framework, for keying application protocols given an established Kerberos V GSS-API security context. This document obsoletes RFC 4402 and reclassifies that document as historic. RFC 4402 starts the PRF+ counter at 1, however a number of implementations starts the counter at 0. As a result, the original specification would not be interoperable with existing implementations.},
