We've recently found out about an interoperability flaw affecting all the HMAC-SHA* algorithms; it affects any key with a secret longer than the digest length of the algorithm (which is 28 bytes, for HMAC-SHA224). If your secret is longer than that, try a shorter key and see if that works.
Just to clarify, does this also apply to HMAC-MD5 (block size = 64 bytes, digest size = 16 bytes) ? -- Chris Thompson Email: [email protected] _______________________________________________ bind-users mailing list [email protected] https://lists.isc.org/mailman/listinfo/bind-users
