The triple-DES (3DES) and RC4 encryption types are steadily weakening
in cryptographic strength, and the deprecation process should begin
for their use in Kerberos.  Accordingly, RFC 4757 has been moved to
Historic status, as none of the encryption types it specifies should
be used, and RFC 3961 has been updated to note the deprecation of the
triple-DES encryption types.  RFC 4120 is likewise updated to remove
the recommendation to implement triple-DES encryption and checksum
