Which encryption slgorithm to use?

Post by Meier, Hors » Thu, 05 Jun 2003 22:03:02



Hi,
PGP supports CAST,AES,TripleDES.IDEA,Twofish. Which of those is to be
preferred? I mean: security not only depends on key-length but also on
quality of the used algo. So, which of those?

If you want be compatible with older versions of pgp, including maybe
other operating systems etc, the choice is IDEA, but if you want
correspond  only among users of the latest windows versions, then AES
might be the right one

One problem with IDEA is that Gnupg usually does not use it.  CAST is a good
alternative.

I've been influenced by Bruce Schneier's new book into
believing a 256
bit algorithm should be used.  And since AES has most
likely had more
peer review, I've updated my FAQ section on this
http://www.mccune.cc/PGPpage2.htm#Symmetric
to show my belief that AES is the best current choice.  Of
course, it is
all debatable.  :-)

| What does that have to do with iteroperability?
|
| GPG does not use IDEA (by default)
