OCKID - question about the format
Paul,
Just one comment about OCKID draft. I think the idea is good: There should be a standard way to represent the hash of the PKI objects.
However, I do not like the idea of using the base32 conversion in converting the binary to ASCII. Numerous programs already out there just use the hex presentation of the SHA-1 hash. See for example, MS certificate viewer in Windows, Netscape, SSH Sentinel, etc.
I suggest that the OCKID would also use the plain HEX representation of the SHA-1 hash. This would make the ID's provided by the programs already out there compatible with OCKID.
The only drawback of this is that you need 24 characters instead of 20 (and probably one for the extra dash).
E.g the example you provided in the draft would become CC48-7D7A A622-8613-E997 instead of 3TEH-48XG-ELDB-H4NZ.
The change would also simplify the draft and the implementation.
What was your motivation for re-inventing the wheel?
Vesa
