Personally, I think the overhead of PGP is way too heavy. Take a
lightening fast xs module like Crypt::Rijndael: it is stronger than
PGP, cleaner, much faster, and does not require shelling out to any
PGP executable.
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. Is, btw, TripleDES also available
for the international versions of PGP?
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.
