    The Encryption/Computer Security Thread!

    Well, for the past few months, I've been in an "encryption/security" phase, and so I feel compelled to start this thread...

    Anyone have any tips?

    "Do's" and "Don't's"?

    Software or encryption algorithm recommendations?

    Witty comments?

    Smartass remarks?



    What sayeth GSUS?

    I use an OLD version of PGP to encrypt files and folders with a 4096-bit DH/DSS cypher.

    I've also used TruCrypt to create an encrypted container to dump files and folders into it. Could also use TruCrypt to encrypt the entire hard drive if you'd like. The only draw back is if your hard drive or partition table ever takes a shit, you'll most likely never get any data back.

    2 words: Open Source

    Don't trust ANY crypto program that's "Proprietary" or commercial, unless they have no problem allowing you to see what's going on "under the hood" in the code.

    Also, when it comes to crypto, the only TRULY unbreakable scheme is the one-time pad, and ONLY if it's implemented correctly. However, it's so cumbersome that for most practical purposes it's impractical.

    I've got an open question - what encryption software would be best to use in conjunction with something like drop box? The idea is you want to store your files in a secure distributed location like drop box or on someone's servers, but you also want your files to be encrypted. Having a big truecrypt container isn't feasible because if you modify one little txt file inside the container, the whole 1 GB container, or whatever size it is, must be re-uploaded in its entirety. Ideally you'd like something that automatically encrypts things on a per-file basis, encrypts file names, and isn't too cumbersome to use when doing productivity work.

    Maybe per-file encryption wouldn't even be optimal, perhaps a multi-part container (sort of like a multi-part rar file) would be optimal.

    There is an open-source program that creates a "Container" file that, once the proper password is entered, mounts the file as a drive, allowing you to modify files inside of it. If your server allows you to access/modify files as a remote file, it will do what you want. Unfortunately, I can't remember the name of it, you'll need to google a bit to find it, but it sounds like exactly what you're looking for. Sorry I can't be more specific on the name...

    It sounds like you're describing Truecrypt.

    That name sounds right. It's been about 5 years since I was really interested in crypto stuff... I've forgotten a lot!

    FreeOTFE is an open source, cross-platform (although I have not yet run it on any of my linux machines yet... I've just played with it a bit on windows) alternative to TrueCrypt, which I believe is proprietary.
