-/*----- Revision history --------------------------------------------------*
- *
- * $Log: blowfish.h,v $
- * Revision 1.5 1998/01/12 16:45:45 mdw
- * Fix copyright date.
- *
- * Revision 1.4 1997/09/26 09:14:57 mdw
- * Merged blowfish branch into trunk.
- *
- * Revision 1.3.2.1 1997/09/26 09:07:59 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.
- *
- * Revision 1.3 1997/08/07 09:43:20 mdw
- * Fix address of the FSF.
- *
- * Revision 1.2 1997/08/04 10:24:20 mdw
- * Sources placed under CVS control.
- *
- * Revision 1.1 1997/07/21 13:47:53 mdw
