Well, here's the response from DataFellows, maker of F-Secure, on wh they
don't have RC5 as an encryption method on their software.

Peter,

Thank you for your interest in Data Fellows Award-winning F-Secure product
line.

You are absolutely correct while pointing to the weakness of DES or any
encryption scheme based on key lengths less than 128 bits. That's exactly
the reason why Data Fellows has from the very first beginning support only
encryption algorithms and keys of 128 bits or more with its F-Secure brand.
Security knows no compromise as far as F-Secure is concerned.

F-Secure products support triple-DES, Blowfish and IDEA which all are
strong encryption solutions. We chose them over RC5 due to their good track
record by security specialists and auditors.

F-Secure SSH Client software is available for Unix (all major Unix
platforms incl. Linux), Windows (Win 3.1, Win'95 and Win NT) as well as for
Mac. F-Secure SSH Server software runs currently on all major Unix platforms
incl. Linux. 

F-Secure SSH client prices are the same, no matter which platform you are
running it on. Client licenses are $99/seat and server licenses $495 each
respectively.  Both come with several price breaks for volume purchases.
Orders will be shipped first come/first serve UPS 2nd day by default (add
$15 for S&H).

If you have any further questions on F-Secure SSH products, please give us a
call at (408) 938-6700, or send us email to F-Secure-sales at DataFellows.com.

Kind regards,

Peter
F-Secure Team

that DES has shown that it's easily crackable, and since 3DES is just DES'd
3 times, I'd suspect that a 128bit RC5 algorhythm is more protection
compared to DES or 3DES, and RC5 is scaleable to any size key.
