Hi all,

are there any suggestions on what we should use for the key-derivation-
function (KDF) mentioned near the end of section 4.3 of security spec?

Paragraph 4 of the section says that there may be an optional key
identifier in the security parameters. If there is, does the security
result still contain the encrypted key? Or should this paragraph say
that we have one or the other, but not both?

Finally, I don't see any specification of key size for AES. I assume
that we therefore should infer that from the key provided. Is this the intent?


Thanks.....Peter
