eID card issuing process
easy to understand examples to explain what happens when creating/verifying digital signatures
answers to several misconceptions about using digital signatures, eID cards, their validity,...
good practices to sign and verify documents to guarantee eternal validity of the signatures, even after the corresponding certificate expired or has been revoked
certificate hierarchy and details on the individual certificates (citizen, CA, government, etc.)
