Vault version 1.9.2 and ssh algorithm type

Hello community out there,

New to hashicorp vault, I can’t find where I can see/confirm the vault 1.9.2 using signing algorithm rsa-sha2-256.
Using vault as SSH certificate authority, as rsa-sha2-256 algorithm since supported openssh 7.2 version.

or where we can see rsa-sha1not be default signing algorithm

thanking you!
