Title:
Improve kernel module signing strength
Status in linux package in Ubuntu:
Incomplete
Bug description:
Signatures are smaller, and do not use problematic RSA-PKCS#1.5
padding.
(SHA-2 standard) SHA512 is also very problematic, because it has no
protection against length extension attacks anymore.
Upgrade to SHA3-512 as used by snap assertions, and is of the same
length & same security bits as current scheme.
