* Generic code for HMAC and NMAC
*
/*----- Revision history --------------------------------------------------*
*
* $Log: hmac.h,v $
+ * Revision 1.6 2001/04/19 18:24:45 mdw
+ * Provide correct key sizes for NMAC, HMAC and SSLMAC.
+ *
+ * Revision 1.5 2001/04/03 19:35:45 mdw
+ * Support the SSL HMAC variant (untested).
+ *
* Revision 1.4 2000/10/15 19:09:20 mdw
* Support HMAC mode for hash functions which need to store more state than
* the hash output size.
