I signed up for a cryptography class at the college I went to here; the class will be Tuesday evenings 6:00PM-9:45PM starting June 21, going through August 16. It should be an interesting class.. Lately I feel that encryption is a gap in my education, and it's relevant to my current job, too.

I love encryption! I hope you encrypt your drives!

I encrypted by drive once, then the passprahse and keys ended up not working when i rebooted and i had to wipe and start over. It was pretty painful.. don't think i will bother with programs like true crypt anymore. Some utils in linux work nice for encrypting the paritions when your install which work alot nicer then trying to encrupt after the install.

Something like that happened to me once.. One time, I discovered that Windows had a drive encryption feature, and I thought that might be useful to keep my data secure, so I decided to encrypt the data partition on my drive. Then that computer had some kind of hardware failure where it wouldn't boot anymore.. I didn't really have the time to figure out what was wrong, so I decided to buy a new computer - it was the only time I ever bought a pre-built computer, and I discovered that I could not easily recover my data partition because it was encrypted.. If I remember right, I think what I ended up doing was plugging my original hard drive into the new computer and booting into Windows on it so that I could read the data partition, and I copyied the data off to an external drive.

I've never used drive encryption again..

Ya i feel the same, thats something i sure as heck don't want to go through again. I blame myself for not backing up stuff before hands but i lost of lot of good coding assignments i did in school which were great references for stuff. I'm still pissed when i think about it now. i have some stuff backed up but i know i missed a lot of things in my advances data structure classes with path find and stuff.. grrrr..

Ugh. Yeah, I've got a huge amount of old iMac, Linux, and I think a BSD image, or two, that are encrypted with passphrases lost to time and/or hardware failure. I'm looking forward to the day when I can get a quantum computing system to help me get back into them. :| Huge tracts of photos and documents from significant portions of my life are trapped in them. Alas...

I've lost a _ton_ of data, and large chunks of my life's record, because of it, but I still use it, every time. I guess I'm just a firm believer in making the NSA's job as hard as I can. Even when they're gonna get it, anyway, the more people that are relying on encryption on a regular basis, making it part of their lives, are making it that much tougher for the NSA to carry out its non-constitutionally sanctioned mission, as opposed to its 'legitimate' operations.
BTW: If anybody is still interested in encryption courses, I'm _just_ signing up again today for this course: https://www.coursera.org/course/crypto, which is starting again on September 8th. I've been most of the way through the course over the past year, but repeated instability in life situations has made it impossible for me to complete. I thought maybe some other people here would be interested in truly understanding the underlying, fundamental algorithms and mechanics.

I've sometimes thought that in the BBS community, sysops should probably enable SSH, and users should probably opt to use SSH over telnet/RLogin since it's encrypted. I've mentioned that once on Dove-Net, but it seemed that the general opinion was that most poeple don't really care much about security for BBS sessions. I've noticed that SSH makes the session a bit slower, but it's nothing major.
