It's a pretty bold claim to say that Rijndael/AES is stronger than
PGP.
PGP can use TripleDES, and you'll have a hard time convincing me that
AES
is stronger than TripleDES. AES is much faster and we hope that is is
stronger, but AES is a young cypher and time will only tell if it's
stronger than TripleDES.
Well, you're right: my claim was a bit bold. :) Friends in the
cryptography
business keep telling me Rijndael/AES is stronger. But since I am not
enough
of a math wizard to verify, or debunk, this myself, I will take your
word
for it that things may not be so clear.
I'm not expert either, just an enthusiast. I was basically just
repeating what I read on Crypto-Gram[1] a couple years ago.
Is, btw, TripleDES also available
for the international versions of PGP?
I don't have access to the PGPi version right now, but I'm pretty sure
that it's included.
Anyway, I have been using Rijndael/AES quite successfully, though, in
Perl,
and it is blazing fast. That is primarily why I mentioned it: it is
fast,
and the extra overhead is quite minimal. From within Perl, calling PGP
is
rather an expensive operation, as it usually requires some
file-preparation
and a system call to the executable to make things go.
Rinjdael/AES was meant to be fast, and it is. I read on the Soekris
mailing list[2] that AES running in software on a 486 CPU is faster
than Soekris' dedicated DES hardware crypto accelerator. Soekris has
now released an hardware AES crypto accelerator[3] that has a 250 Mbps
throughput.
Good night,
