* fix!: Disable use of weak RSA key sizes for asymmetric algorithms
Added checks to prevent invalid secrets from being used with the HS*** algorithms when signing and verifying
Added checks to prevent the use of insecure asymmetric key sizes except when explicitly overriden via options
Prevented Buffers containing malicious objects from being used as key material.
BREAKING CHANGE: Requires node 12.x or later to allow use of `KeyObject`
