RE: A little social engineering
Would you like to write an "ESP Shim" document proposing it?
At this point the following ciphers have been talked about (I'm talking in
vague terms here, just from my knowledge)
3DES-EDE (I think that's how you say it precisely...)
CASTv5-128 (I trust Mr. Adams and/or the draft writers will correct my
When I did the ARCFOUR cipher draft last spring I would hear from people --
"what about Blowfish", "What about CAST", "What about Safer", "What about
SEAL", etc. Actually I think that's the three I heard people mention.
I believe we can only think about the ones we've got ESP and/or DOI
"paperwork" written for. That means, today, we think about RC5 and CAST
and 3DES. You want Safer? This is a reasonable question, I believe, but
someone has to write a draft...
