A digital certificate is an electronic file that verifies the identity of the holder. It contains identification information, such as a public key for encrypting and decrypting messages, and a digital signature from a certification authority to confirm the certificate’s authenticity. Websites use digital certificates to assure customers that they are genuine, forming the security foundation for HTTPS.
What Exactly Is a Digital ID?
A digital ID, or digital certificate, is essentially an electronic form of identification. Think of it as a virtual passport or driver’s license that confirms your identity in online transactions. It’s an electronic file containing your identification information and a public key for secure communication.
