But i’m wondering if there if somehow a way to tell neos to use a certificate to communicate with redis?
For transport encryption or for client authentication?
Transport encryption is possible since Flow bugfix releases: 7.3.16, 8.0.13, 8.1.9, 8.2.7 & 8.3.5 as the hostname can now be prefixed with tls:// or tlsv1.2:// to enable TLS (before Flow would then assume a socket connection should be used.)
Client authentication as per the documentation seems to be a question of having (only) the correct certificates trusted (in the CA cert used by the server). TBH, I have no idea how this is supposed to work, I see no way to configure the certificate to use in the client…
