Decrypting kerberos ticket

[Noolyg]

Hi,

I use MIT's kerberos library, and I have got several problems...
I was wondering what is the best way to decrypt a kerberos ticket
(krb5_ticket)?
I saw the krb5_decrypt_ticket_part func but it is private...
Is there an alternative?

And another thing is how do I get the krb5_keyblock? I can have the
kerberos key as a string, but how do I convert it to a keyblock?

Thanks a lot.
