Richard had previously requested that we register algorithm identifiers for AES
using 192 bit keys. As he previously pointed out, "It seems like if we're
going to support AES, then we should support AES. Every AES library I know of
supports all three key lengths, so it's not like there's extra cost besides the
registry entry." (I'll note that we already have algorithm identifiers for the
"mid-size" HMAC and signature functions "HS384", "RS384", and "ES384".)
I heard no objections at the time. I'm therefore thinking that we should
register algorithm identifiers for these key sizes as well. Specifically, we
would add:
"A192KW", "ECDH-ES+A192KW", "A192GCMKW", "PBES2-HS256+A192KW", "A192CBC-HS384",
and "A192GCM". Support for these algorithms would be optional.
What do people think?
