I know rsyslog is using gnutls (default) with a recommendation for openssl and has support for TLS-encrypted TCP connections. Does rsyslog support TLS-encrypted UDP connections (specifically, inbound)?
No, TLS requires a stream of packets as the encryption for each packet changes based on the prior packets., UDP syslog has each packet handled completely independently, and packets can get reordered or dropped on the network before they are processed, so TLS really can't work.
