The University of Tartu uses two certification service providers to order certificates for websites, LetsEncrypt and Sectigo. - In the paid web hosting server webhost.ut.ee it is possible to choose both solutions, LetsEncrypt is set by default.
- sisu.ut.ee uses only LetsEncrypt.
- In all other cases, depending on your skill, you can set up either LetsEncrypt or order a certificate through IT helpdesk for Sectigo CA.
- Webhost.ut.ee and sisu.ut.ee LetsEncrypt service is set up by ITO employees. Sectigo CA certificates are mostly ordered by ITO and HPC employees, but if there is a justified need, we create a Sectigo certificate ordering account for non-ITO UT employees as well.
LetsEncryptLetsEncrypt - a free service that requires the installation of a certificate renewal utility on the web server. This is necessary because LetsEncrypt only issues certificates with a validity period of a few months. The website must be open to the entire Internet to order and renew the certificate. Detailed instructions can be found on the service provider's web portal. SectigoNB! This section is only for those who have a valid Sectigo certificate ordering account. The procurer of the service contract is GÉANT, it is managed to the University of Tartu by EENet operating under HTM. The Sectigo CA service is free for UT. Based on the current terms of service, Sectigo certificates may be ordered only for domain names registered in the name of the University of Tartu. The certificate is valid for a maximum of one year, it can be ordered both through the service provider's web portal and via the ACME protocol with certbot scripts. |
