  * $Log: icrypt.h,v $
+ * Revision 1.3  1997/09/26 09:14:58  mdw

+ * Revision 1.2.2.1  1997/09/26 09:08:08  mdw
+ * Use the Blowfish encryption algorithm instead of IDEA.  This is partly
+ * because I prefer Blowfish (without any particularly strong evidence) but
+ * mainly because IDEA is patented and Blowfish isn't.
