cryptography through perl 1

[ranadhir]

I am sorry if this question seems too broad-based.
Our objective is to encrypt data using a known key(user-specified) in C++;and decrypt the same in Perl,using the same key.
We intend to use TripleDES algorithm for the same.
Is this possible through Microsoft CryptoAPI for C++ and Crypt::TripleDES in Perl?
If so,a sample code would be a life-saver.

You could always just go ahead and try it. ;-)

the Crypt::TripleDES module requires another module:

Crypt:PDES

but it's not on CPAN.

Crypt::TripleDES comes with Crypt:PDES in its distribution:

http://search.cpan.org/src/VIPUL/Crypt-TripleDES-0.24/lib/Crypt/

ahh, I should have checked that! A star for you.

I tried this with a VB implementation of Blowfish, many moons back, and I ended up having to shell to a perl exe to do the decryption, as it was encrypted on a *nix webserver. The salts seemed identical, but the results were less identical, if you know what I mean ;-)

Run up a noddy sample, and see how you get on, just as a proof of concept

Still struggling to find a way to work on encrypting in C++ and decrypting in perl using DES/TripleDES.
Any samples would be helpful;before i take the extreme step of invokig c++ routine from perl to decrypt.
I am able to encrypt/decrypt in c++ using crypto API;and do the same in perl using Crypt;but no idea how to make it work across the languages.
