Subject: Add RSA SHA512 truncated digest support
X-Git-Tag: openssl-3.0.0-alpha2~65
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=45c236ad1f1c881281017941a0e7126735a190e8;p=oweals%2Fopenssl.git

Add RSA SHA512 truncated digest support

Partial Fix for #11648.

Some additional work still needs to be done to support RSA-PSS mode.

RSA legacy digests will be addressed in another PR.
