Returns a hash containing the permitted encoding types. The key is the numeric constant, with a string description as its value.

Example:

  krb.get_permitted_enctypes

  # Results:
  {
     1  => "DES cbc mode with CRC-32",
     2  => "DES cbc mode with RSA-MD4",
     3  => "DES cbc mode with RSA-MD5"}
     16 => "Triple DES cbc mode with HMAC/sha1",
     17 => "AES-128 CTS mode with 96-bit SHA-1 HMAC",
     18 => "AES-256 CTS mode with 96-bit SHA-1 HMAC",
     23 => "ArcFour with HMAC/md5"
