KERB_ETYPE_DES_CBC_MD4
 Use DES encryption in cipher-block-chaining mode with a MD4 checksum.
KERB_ETYPE_DES_CBC_MD5
 Use DES encryption in cipher-block-chaining mode with a MD5 checksum.
KERB_ETYPE_NULL
 Use no encryption.
KERB_ETYPE_RC4_HMAC_NT
 Use the RC4 stream cipher with a hash-based Message Authentication Code (MAC).
KERB_ETYPE_RC4_MD4
 Use the RC4 stream cipher with the MD4 hash function.
 

Values greater than 127 are reserved for local values and may change without notice.
