> Traditionally, an asymmetric key has a key size. The size is displayed by `keytool` and `jarsigner`, both in informational output and weak-key warnings. However, for the recently added ML-DSA algorithm, key size is not defined.
>
> Thus when an ML-DSA key is created, `keytool` shows
>
> Generating -1 bit ML-DSA-65 key pair...
>
> When the entry is being displayed by `keytool -list -v`, it shows
>
> Subject Public Key Algorithm: -1-bit ML-DSA-65 key
>
> If the algorithm is disabled, `keytool -list` shows
>
> <x> uses a -1-bit ML-DSA-65 key which is considered a security risk...
>
> Furthermore, if a JAR file is signed by ML-DSA, `jarsigner -verify` also shows
>
> Signature algorithm: ML-DSA-65, unknown size
>
> or when the algorithm is disabled, it shows
>
> Signature algorithm: ML-DSA-65, -1-bit key (disabled)
> The ML-DSA-65 signing key has a keysize of -1 which is considered a security risk.

> With this code change, a key can either has a key size, or characterized by a `NamedParameterSpec`, and the display chooses one of them.
>
> One special case is EC keys, which have both a keysize and a `NamedParameterSpec`. Both are displayed.
