Thanks, LGTM. CI: https://ci.nodejs.org/job/node-test-pull-request/21140/

Maybe a minor suggestion vis-a-vis the commit log summary: crypto: add KeyObject.asymmetricKeySize?

The link to the issue should be Fixes: https://github.com/nodejs/node/pull/24234 on its own line.

edit: make that Refs: https://github.com/nodejs/node/pull/24234

👋 Maybe i'm missing something but EVP_PKEY_size returns the maximum signature size in bytes, not the actual key size.

This is apparent with Ed25519 and Ed448 and possibly EC keys as well.

pem =`-----BEGIN PUBLIC KEY-----\nMCowBQYDK2VwAyEAEXRYV3v5ucrHVR3mKqyPXxXqU34lASwc7Y7MoOvaqcs=\n-----END PUBLIC KEY-----`
k=crypto.createPublicKey(pem)
// PublicKeyObject { [Symbol(kKeyType)]: 'public' }
k.asymmetricKeyType
// 'ed25519'
k.asymmetricKeySize
// 114

114 bytes is the length of a signature, key is in fact 57 bytes

@panva That's probably worth posting a new issue for.

i only checked it with RSA, since there are only RSA tests for the KeyObject in the repository. Maybe we should just rename the property and/or change the documentation, to match the returned value

I'm assuming this should have been marked as semver-minor.

I'll back out this PR from v11.12.0 due to the concerns by @tniessen. If this should indeed land in a PR, please update the labels accordingly.
