 * Revision 1.1  2004/03/15 20:35:25  as
 * added files from freeswan-2.04-x509-1.5.3
 *
 * Revision 1.7  2002/09/10 01:45:09  mcr
 * 	changed type of MD5_CTX and SHA1_CTX to void * so that
 * 	the function prototypes would match, and could be placed
 * 	into a pointer to a function.

 * Revision 1.6  2002/04/24 07:36:47  mcr
 * Moved from ./klips/net/ipsec/ipsec_sha1.h,v
 *
 * Revision 1.5  1999/12/13 13:59:13  rgb
 * Quick fix to argument size to Update bugs.
 *
 * Revision 1.4  1999/12/07 18:16:23  rgb
 * Fixed comments at end of #endif lines.

 *
 * Revision 1.2  1998/11/30 13:22:54  rgb
 * Rationalised all the klips kernel file headers.  They are much shorter

 *
 * Revision 1.1  1998/06/18 21:27:50  henry
 * move sources from klips/src to klips/net/ipsec, to keep stupid
 * kernel-build scripts happier in the presence of symlinks
 *
 * Revision 1.2  1998/04/23 20:54:05  rgb
 * Fixed md5 and sha1 include file nesting issues, to be cleaned up when
 * verified.
 *
 * Revision 1.1  1998/04/09 03:04:21  henry
 * sources moved up from linux/net/ipsec
 * these two include files modified not to include others except in kernel
