Hey everyone... cryptography is not really my strong point and I'm trying to do something I thought should have been fairly easy. We have a number of machines running various versions of FreeBSD from 4.7-RELEASE to 4.8-STABLE. Our password files for our users are generated through passwords which are currently being stored in plain text. I wish to encrypt these on a central server and store them in the database for better security, however I'm running into some problems. It appears to work on some systems and some systems it does not. I have tried DES and MD5 encryption. Most of these systems have been upgraded from much earlier releases of the 4 branch, and the passwords of users not generated from the database seem to have been find after each upgrade. So my question is, what am I doing wrong? Is there a way to encrypt a password on one system and have it work on all FreeBSD machines no matter what release its running? If I encrypt on a 4.7 box will it work on a 4.8 system, just not the other way around? Thanks for any help of information you can provide. Sincerely, James Moser
