[pve-devel] [PATCH manager master+stable-8] pve8to9: improve error/log message for tls checks

[Dominik Csapak]

we check different key sizes for RSA (2048) vs ECC (224) but the
logs/error always wrote '2048' which can be confusing if ECC keys are
used, for example:

PASS: Certificate 'pveproxy-ssl.pem' passed Debian Busters (and newer) security level for TLS connections (256 >= 2048)

Use the actual size and type we check against in the log/error so reduce
confusion.

The new log line is then:

PASS: Certificate 'pveproxy-ssl.pem' passed Debian Busters (and newer) security level for TLS connections (256 >= 224 ECC)

this is based on master, but should be cleanly cherry-pickable on
stable-8 currently
