TLS certificates

We have two options:

1. LetsEncrypt certificates

For services exposing the http port to the internet, certificates can be automated:

2. Trusted Certificate Service by GÉANT

The Trusted Certificate Service (TCS) is delivered by the Hellenic Academic & Research Institutions Certification Authority (HARICA).
