Public Key Infrastructure (PKI)
A framework for managing digital certificates and public-key encryption. PKI enables secure electronic communication and digital signature verification.
PKI uses pairs of cryptographic keys — a public key (shared openly) and a private key (kept secret). When signing, the signer's private key creates the signature. Anyone with the public key can verify it.
Qualified Electronic Signatures under eIDAS require PKI-based certificates issued by trusted service providers.
