Simple question on multiple mac/encryption algorithm

[Gustavo Rios]

Hi folks,

could some one confirm the following two assertives:

1) KerberosV uses a modular approach, allowing any encryption
algorithm to be used stead of DES, i.e., ones could implement
RC2/RC4/RC5/cast128/cast256 and any other to be used within kerberosV
clients/server.

2) This same modular approach allows for any MAC algorithm to be used,
like md4/md2/md5/sha1/rmd160, provide both parties agree on that.

Sorry, i have not read the documentation for these very simple
question.

Thanks a lot for your time and cooperation.
best regards.

PS: If  possible, reply to me too.
