Subject:  Minutes of 011119-tele

                             W3C XML Encryption WG

  Chair: Joseph Reagle

         1. I want it fixed that 168 bit keys are transported in 192 bit
            form, that's all.
            Defer to Eastlake.

**AP** Previously I had commented about confusing transport mechanisms and
key sizes for DES keys. The issue is also crypto APIs. I am not aware of
any crypto API that that accepts just a 56 bit key without the parity bits,
e.g. storing a DES key in just 7 bytes. All the crypto APIs I'm familiar
with always include the parity bits, whether or not they are used, hence
storing a DES key in 8 bytes. Ditto for 3DES keys, whether 112 or 168 bits.
