Utility to test IDEA encryption algorithm

[sameergn]

Hi,

I have written a program in Java to encrypt text using IDEA algorithm
(http://www.finecrypt.net/idea.html)

I need a utility to test my program. Is there any IDEA encryption tool
that will let me encrypt some text so that I can compare its output
with my tool? I know that I can write decryption routine and test my
encryption but it will take me some time to do that.

Thanks,
Sameer

You could use OpenSSL to cross-check your IDEA algorithm:
http://www.openssl.org/

Might not be an issue for you, but now that I look at it the version
supplied with Fedora Core 3 wasn't compiled with IDEA support.

Thanks for your reply.
I found the PPT at
http://www.cc.gatech.edu/classes/AY2001/cs8803g_spring/crypto8_1.ppt
extremely useful for debugging the encryption part. It gives all the
intermidiate bit values for all 8 rounds. It helped me in identifying
bugs in my modulo multiply routine.
