Steve:
I have ftped and read your internet draft on the FTP security
extensions. I think the proposed extensions address most of
of the security needs. Two minor comments are:
- Sometimes, there is no clear separation between authentication
and authorization. Thus the commands AUTH, ADAT, USER PASS
maybe organized in a different manner to address it.
- On the encryption of ascii text, is it possible to have some
buffering scheme to avoid encoding each charactor individully?
BTW, how do I subscribe the mailing list cat-ietf@mit.edu?
