Asymmetric encryption algorithms.

This type is for refining the StandardPolicy with respect to asymmetric algorithms. In contrast to PublicKeyAlgorithm, it does not concern itself with the use (encryption or signing), and it does include key sizes (if applicable) and elliptic curves.

Key sizes put into are buckets, rounding down to the nearest bucket. For example, a 3253-bit RSA key is categorized as RSA3072.

Note: This enum cannot be exhaustively matched to allow future extensions.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
