[security-dev 00571]: Re: inefficient Des3DkCrypto/DigestMD5Base.setParityBit()

[Brad Wetmore]

You'd want to talk to Max (Weijun) as he has primary responsibility for 
the Kerberos code, but so far it sounds very reasonable to me.

Looks like you are setup in the SCA database, it would be best to 
discuss it here with Max and others that would be interested, and if you 
develop a patch, please file it in the new bugzilla instance. 
http://bugs.openjdk.java.net

Thanks, good luck!
