Subject: Wrong Key length in MS-BKRP 3.1.4.1.2.1 Processing a Valid ServerWrap 
Wrapped Secret

G'Day,

The MS-BKRP protocol docs at "3.1.4.1.2.1 Processing a Valid ServerWrap Wrapped 
Secret" (point 1) and "3.1.4.1.1 BACKUPKEY_BACKUP_GUID" (point 3) clearly state 
that the first 64 bytes of the secret are used for the key.  This is not the 
case - testing by extracting the key from the Windows DC over LSA QuerySecret 
show that the entire key (256 bytes), not the first 64 bytes, is used.

Please correct the docs. 

Thanks,

Andrew Bartlett
