Restore RSA-PSS and the “RSA” key type

[selfissued]

RSA cryptography remains the mostly commonly used in many applications. Please restore the descriptions of the RSA-PSS algorithm and the “RSA” key type.

Note that if this isn’t done, you should say that there are three key type values defined in Table 18, not four.

Parked waiting for a consensus call

There’s a reasonably strong consensus to define RSA PSS support in an auxiliary draft. The chairs would like to ask for volunteers to edit such an auxiliary draft.

I'm willing to be an editor for this auxiliary draft. I would welcome a co-editor who also sees the value in defining appropriate COSE identifiers to be able to use RSA keys and cryptography with COSE.

The draft https://tools.ietf.org/html/draft-jones-cose-rsa-00 is intended to address this issue.
