Go 1.23 changed the default TLS cipher suites used by clients and servers when
not explicitly configured, removing 3DES cipher suites. The default can be reverted
using the [`tls3des` setting](/pkg/crypto/tls/#Config.CipherSuites).

Go 1.23 changed the behavior of [`tls.X509KeyPair`](/pkg/crypto/tls#X509KeyPair)
and [`tls.LoadX509KeyPair`](/pkg/crypto/tls#LoadX509KeyPair) to populate the
