Fast File Encryption for Windows?

Posted by ryuzaki0 on from the speed-over-security dept.

cryptoz wonders: "I've used numerous encryption applications for both Windows and Linux over the past few years and have always been satisfied. Until I realized I needed to start encrypting large files (say 10 to 30 GiB), or at least a large number of small(er) files. I found that everything I use seems to take hours and hours to compress, encrypt and shred. Not to mention decompressing, decrypting and deleting on the other end. Every web search I do on the topic seems to turn up mostly closed-source applications or snake oil, neither of which is acceptable. Does Slashdot have any suggestions for fast file encryption? I should make it clear that in my particular case, I do not need to have a perfect key or incredibly secure encryption, since it is not the weakest link (as I am susceptible to hardware key-loggers, CRT eavesdropping and the like). The encryption needs to be just strong enough, but most importantly, *fast*." This is a worthwhile question, but when dealing with files in the 10s of GB, can anything really be considered to be "fast"?

    But you should look at TrueCrypt

    Ever tried this? SureCrypt

    SureCrypt is an ultra small encryption program designed for fast processing of extremely large files. It can encrypt or decrypt files as fast as Windows Explorer can copy them. SureCrypt presents a flexible user interface with detailed record of all operations.

  3. Isn't TrueCrypt Linked in the POSTING? by neonprimetime · · Score: 5, Insightful

    Ok ... is it just me, or is TrueCrypt linked IN THE FREAKIN' POSTING ABOVE? Why is everybody's answer of "TrueCrypt" getting modded as informative?

  4. Hardware acceleration. by wild_berry · · Score: 5, Interesting

    I suggest getting some hardware acceleration: the VIA EPIA boards use electrical interference in their traces to suppy entropy to a hardware encrypt/decrypt enginge that can achieve 25 Gb/s encryption. This is a 1.0GHz passively-cooled board with SATA ports, hardware MPEG2 decoding and all on a 17x17 cm^2 board.
