- Use an elliptic curve key (NIST P384) for module signing. Consider
- using a strong hash like sha256 or sha384 for hashing modules.
+ Use an elliptic curve key (NIST P384) for module signing. Use
+ a strong hash of same or higher bit length, i.e. sha384 or
+ sha512 for hashing modules.
Note: Remove all ECDSA signing keys, e.g. certs/signing_key.pem,
when falling back to building Linux 5.14 and older kernels.
