However, the fix may - cause incompatibility between older and newer versions of - BIND, when using long keys. <span><strong class="command">isc-hmac-fixup</strong></span> - modifies those keys to restore compatibility. - </p> -<p> - To modify a key, run <span><strong class="command">isc-hmac-fixup</strong></span> and - specify the key's algorithm and secret on the command line. If the - secret is longer than the digest length of the algorithm (64 bytes - for SHA1 through SHA256, or 128 bytes for SHA384 and SHA512), then a - new secret will be generated consisting of a hash digest of the old - secret. (If the secret did not require conversion, then it will be - printed without modification.) - </p> -</div> -<div class="refsect1" lang="en"> -<a name="id2543379"></a><h2>SECURITY CONSIDERATIONS</h2> -<p> - Secrets that have been converted by <span><strong class="command">isc-hmac-fixup</strong></span> - are shortened, but as this is how the HMAC protocol works in - operation anyway, it does not affect security. RFC 2104 notes, - "Keys longer than [the digest length] are acceptable but the - extra length would not significantly increase the function - strength." - </p> -</div> -<div class="refsect1" lang="en"> -<a name="id2543393"></a><h2>SEE ALSO</h2> -<p> - <em class="citetitle">BIND 9 Administrator Reference Manual</em>, - <em class="citetitle">RFC 2104</em>. - </p> -</div> -<div class="refsect1" lang="en"> -<a name="id2543410"></a><h2>AUTHOR</h2> -<p><span class="corpauthor">Internet Systems Consortium</span> - </p> -</div> -</div></body> -</html> |
