Improvements

  • Comparing certificates - two ways to compare certificates have been added:
  • Side-by-side textual comparison: By selecting two certificates in the main view and choosing "Compare" in the context menu, a summary of the most important certificate data and an ASN.1 dump of both certificates is displayed side by side and the differences are marked in a contrasting color (contributed by Jairo Graterón).
  • Multiple certificate view dialogs: The certificate viewer dialog is now non-modal, which means several instances of this dialog can be kept open at the same time. This allows to view multiple certificates at the same time (contributed by Piotr Kubiak).

  • Size of generated certificate serial number (contributed by dedabob)
  • FlatLaf macOS themes
  • Added functionality to examine JWT in system clipboard (contributed by Afonso Fernandes)
