Many users end up signing certificates these days. Especially if you don’t usually log in to USERMAP, be careful not to be surprised when you ask for a holiday, for example. You can issue a new certificate at https://obelisk.cvut.cz and follow chapter 5 – “Renewal of the certificate” of the User Portal for remote signature management of the OBELISK system (OBELISK USERPORTAL) https://ist.cvut.cz/en/support/user-manuals/manual-obelisk/. More information about electronic signatures can be found at https://ist.cvut.cz/en/our-services/digital-certificates/.
