I have released the latest version of my DES patchkit for SSH. It
patches the latest version of SSH (1.2.22) to include x86 asm
implementations of DES and 3DES that are several times faster than
their portable C implementations. On a Pentium, my single DES code is
about as fast as Blowfish and my 3DES code is about as fast as IDEA.
The patched SSH package will still compile and run on non-Intel
machines. It just won't be any faster.
You can get the kit from Michael Johnson's export-controlled North
American Cryptography Archives website, http://www.cryptography.org/.
When you get past the entrance form, go into the raw http or ftp
directory and look for the ssh subdirectory. It's there along with a
mirror of the base ssh code (ssh-1.2.22.tar.gz).
Note that I've included a PGP signature for my patchkit as well as
Tatu's own signature on the base package. I recommend checking them
before installation, and I ask anyone who mirrors my code to carry my
signature as well. (One would think that anyone using SSH would know
better than to install an untrusted patchkit, but then you never
know...)
