The Kerberos 5 network authentication protocol, originally specified
in RFC1510, can use the Data Encryption Standard (DES) for
encryption. Almost 30 years after first publishing DES, the National
Institute of Standards and Technology (NIST) finally withdrew the
standard in 2005, reflecting a long-established consensus that DES is
insufficiently secure. By 2008, commercial hardware costing less
than USD 15,000 could break DES keys in less than a day on average.
DES is long past its sell-by date. Accordingly, this document
updates RFC1964, RFC4120, RFC4121, and RFC4757 to deprecate the use
of DES, RC4-HMAC-EXP, and other weak cryptographic algorithms in
Kerberos. Because RFC1510 (obsoleted by RFC4120) supports only DES,
this document reclassifies RFC1510 as Historic.
