Keytab encryption types list

Let’s imagine that we needed to determine what principles and what encryption types exist in a certain keytab. To do this, we will use the ktutil utility:

/usr/bin/ktutil

After we have entered the CLI of this utility, we type the following commands:

read_kt your_keytab.keytab
list -e

Something like this will be displayed:

slot KVNO Principal
---- ---- ---------------------------------------------------------------------
   1   12               principal@REALM (aes256-cts-hmac-sha1-96)
   2   12               principal@REALM (aes128-cts-hmac-sha1-96)
