  38  *
  39  * Revision 1.7  2002/09/10 01:45:09  mcr
  40  *      changed type of MD5_CTX and SHA1_CTX to void * so that
  41  *      the function prototypes would match, and could be placed
  42  *      into a pointer to a function.
  43  *
  44  * Revision 1.6  2002/04/24 07:36:47  mcr
  45  * Moved from ./klips/net/ipsec/ipsec_sha1.h,v
  46  *
  47  * Revision 1.5  1999/12/13 13:59:13  rgb
  48  * Quick fix to argument size to Update bugs.

  50  * Revision 1.4  1999/12/07 18:16:23  rgb

  53  * Revision 1.3  1999/04/06 04:54:27  rgb
  54  * Fix/Add RCSID Id: and Log: bits to make PHMDs happy.  This includes
  55  * patch shell fixes.
  56  *
  57  * Revision 1.2  1998/11/30 13:22:54  rgb

  60  *
  61  * Revision 1.1  1998/06/18 21:27:50  henry
  62  * move sources from klips/src to klips/net/ipsec, to keep stupid
  63  * kernel-build scripts happier in the presence of symlinks
  64  *
  65  * Revision 1.2  1998/04/23 20:54:05  rgb
  66  * Fixed md5 and sha1 include file nesting issues, to be cleaned up when
  67  * verified.
  68  *
  69  * Revision 1.1  1998/04/09 03:04:21  henry
  70  * sources moved up from linux/net/ipsec
  71  * these two include files modified not to include others except in kernel
  72  *
  73  * Revision 1.1.1.1  1998/04/08 05:35:04  henry
