Recent patches to cryptodev removed support for insecure, broken or
weak x509/pkcs7 signing hashes MD4, MD5, SHA1, SHA-224. This opens
room to add SHA-3 family of hashes, which are not yet broken.
Add support for FIPS 202 SHA-3 in x509 RSA & ECC certs, pkcs7
signatures, hash info structs. And adjust documentation.
This enables using SHA-3 family of hashes for kernel module signing.
For SHA3+ECC signing openssl with this patch [0] is needed, currently
in openssl development tip. SHA3+RSA signing is supported by stable
openssl.
kmod needs a patch to recognise SHA3 hash names [1], submitted
separately.
This patch series is on top of tip of cryptodev git repository commit
a2786e8bdd ("crypto: qcom-rng - Add missing dependency on hw_random")
