WebNov 20, 2014 · Between the client and server, a Kerberos authentication server acts as the trusted third party. The authentication server forwards client usernames to a key distribution center (KDC). Kerberos 5 (krb5-x) uses AES with 128-bit blocks and key sizes of 128 or 256 bits. Legacy versions of Kerberos used DES, which is incredibly insecure these days. WebMaintenance. Since CWE 4.4, various cryptography-related entries, including CWE-327 and CWE-1240, have been slated for extensive research, analysis, and community consultation to define consistent terminology, improve relationships, and reduce overlap or duplication.
