- This is not true. From experience, I can tell you that code compiled with
- the MIT libkrb.a and libdes.a is compatible with code compiled with the
- ULTRIX versions of those libraries. The only difference is that the
- ULTRIX libraries don't have any routines which allow encryption of raw data -
- any functions or programs which need to encrypt/decrypt have the algorithm
- in-lined into them. The algorithm itself is the same.
-
- As far as the Kerberos daemon itself is concerned, there are only a few
- lines different between the MIT code and the ULTRIX code, none of which
- have to do with encryption.
-
- As an experiment, I tried just now running an ULTRIX Kerberos daemon with
- an MIT kadmind, and the MIT kadmin client. Worked fine here.
-
- My guess is that there's something different between your DES routines
- and the ones MIT used.
-
- With regards to the exportability issue, from what I've seen getting export
- permission is not difficult providing you can prove that what you ship
- doesn't allow encryption of random data streams. Encryption for the purposes
- of authentication is OK; "encryption for encryption's sake" is not.
-
- Disclaimer: I'm not speaking as any sort of "official representative", merely
- as one who has access to both ULTRIX and MIT sources.
