Choose Y to enable the use of deprecated Kerberos 5
encryption types that utilize Data Encryption Standard
(DES) based ciphers. These include des-cbc-md5,
des-cbc-crc, and des-cbc-md4, which were deprecated by
RFC 6649, and des3-cbc-sha1, which was deprecated by RFC
8429.
These encryption types are known to be insecure, therefore
the default setting of this option is N. Support for these
encryption types is available only for compatibility with
legacy NFS client and server implementations.
Removal of support is planned for a subsequent kernel
release.
