I've been sent this requst indirectly, and thought it best to forward it to these lists, anonymously. I will forward any replies to the original sender. -M Taylor ------------------- Hi guys. Sorry that this is a little off topic, but I figure that here is my best chance to find this information, all other resources (save damned reverse engineering) having been exhausted. If you have used Pegasus mail before, you would know that it provides an internal encryption function. This is some form of DES, accourding to their web site, and is presumably < 40 bits, as they quite happily allow worldwide downloads of the binard from the US. However, actual details on which form of DES, and how they turn an input password into a key were not supplied. Now, my company decided that this encryption was just dandy for security, and that everyone should use it for all encrypted mail. This, along with their idiocies about passwords used have me quite annoyed - but that is *far* from the point of this. What I am wanting to do, so as not to have to give up my nice, efficient unix mailer, while retaining the abilitiy to work with others is implement (or locate an implementation of) the Pegasus encryption, and then do a little hacking and add that to my mailer. The main problem is: no idea what the format of the DES used is. So, if anyone could supply me with a simple answer to this question, I would be very apreciative. Thanks, xxxx
