- Asymmetric algorithms, generally: RSA-ES, DSA.
Are you referring to Public Key Algorithms specifically here? in
particular, this table:
https://tools.ietf.org/html/rfc4880#section-9.1
If so, RSA-ES (pubkey algorithm 1) is very widely used, even for keys
that are only marked for one usage (signatures or encryption). In fact,
i don't think there are many RSA keys labeled RSA-E (algo 2) and RSA-S
(algo 3) at all. Why treat RSA-ES separately for deprecation?
In fact, aren't the RSA-E and RSA-S algorithms basically just historical
/ mostly deprecated in favour of marking keys for a particular use?
