WARNING: This Message Actually Contains a Question Reguarding Crypto!

Hi,

I just recently downloaded copies of Blowfish & Ghost.

Does anyone have any experiance with these two algorithims?

How do they comare to RSA, DES, 3DES, IDEA ?

I can across a post awhile back that mentioned that they were using Blowfish in
PGPPhone. Can anyone confirm this?

Does anyone know how they are using Blowfish and why?

Thanks,

Don't use GOST unless you think you can come up with some good S-boxes.  It's  
pretty much only out there for educational purposes.

A program called F-Secure Desktop for Windows 3.x and Windows 95 is using
Blowfish with 256-bit keys. It is meant for encrypting the files on your
hard disk and it works nicely together with Windows File Manager or
Windows95 shell. I would say it is one of the best strong and easy to use
HD encryption programs (only that it costs $$).

It is manufactured by Datafellows, who is also distributing F-Secure SSH.
You can download the demo version at http://www.datafellows.com/f-secure/

Why they are using it: may be because it is fast on Intel Pentium and
Pentium Pro processors, as discussed in Applied Cryptography?

Blowfish is unpatented and the source code doesn't have any restrictions.  If
they used something like IDEA, they would have to pay for a license.  I don't
know if Blowfish is faster than 3DES, but if it isn't, then I have no idea why
they would use Blowfish.
