XCA is intended for creating and managing X.509 certificates, certificate requests, RSA, DSA and EC private keys, Smartcards and CRLs. Everything that is needed for a CA is implemented. All CAs can sign sub-CAs recursively. These certificate chains are shown clearly. For an easy company-wide use there are customiseable templates that can be used for certificate or request generation.
Features:
Installed the flathub version 2.4.0 of XCA. Tried to create a new database but failed due to an 'open' error. Uninstalled & reinstalled the package version which worked just fine. No problem creating a new database.
