What are Digital Certificates?

Digital certificates are electronic mechanisms that verify the identity of individuals or organisations. They're used to authenticate users and electronically sign data and documents, ensuring the signatory's identity and the integrity of the content.

How do digital certificates work?

  • Digital certificates are issued by trusted third parties known as Certificate Authorities (CA), accredited under regulations like eIDAS or Webtrust.
  • Upon obtaining a digital certificate, the Certificate Authority (CA), like, confirms your identity and issues you a certified digital certificate. This document includes your personal information, a public key, and a private key. Your private key remains securely under your control, while the public key can be shared with others. You can share your public key with third parties.
  • Encrypting with one key ensures that only the corresponding key can decrypt the data, guaranteeing secure communication and authentication online. Encrypting with the public key means decryption can only occur with the private key, and vice versa
  • This means your public key is used to encrypt data, ensuring only you can decrypt it due to your exclusive access to the private key. Your private key is then utilized to sign documents or data, enabling anyone with the public key to decrypt the message and confirm that only you could have signed that document or data.
