   This is the second time in the week that I have heard 'RC5', and have not
   heard it mentioned before this.
   
   I realize that many things happen in the crypto field that I do not see
   right away, but how recent is the introduction of RC5 to the broader crypto
   community?

~1995 or thereabouts.  This is a *very* new cipher, so it's not
something I'd actually want to implement or use until it's had a
lot more shakeout time.

See Ron Rivest's publications web page:

	http://theory.lcs.mit.edu/~rivest/publications.html

which contains:

	The RC5 Encryption Algorithm by Ronald L. Rivest. (To appear in
	Proceedings of the 1994 Leuven Workshop on Algorithms (Springer).) 

which is a link to:

	http://theory.lcs.mit.edu/~rivest/rc5.ps

The source code included in the paper is "(C) 1995 RSA Data Security
Inc.".
