Seems like an important thing missing from the JDK Providers guide. The documentation should also include the string that can be used to select the curves in e.g. ECGenParameterSpec.

Please consult with the security libraries team to get this list.

The users may need to know the supported curves. I did not find the
the general definitions in the "Java Security Standard Algorithm
Names" documentation, except the x25519/x448. We may need another RFE for adding the standard and supported algorithm names for EC curves.

Max is working on support named curves in keytool. Therefore, the users need to know the curve names before they can use the option.

The bug JDK-8208156 is asking for document EC curves in JCE providers. We may also need to document in the standard names documentation so that different providers can support the same names.
