Explanation
In PKI, public keys are distributed through digital certificates. A digital certificate is an electronic document issued by a Certificate Authority (CA) that binds an entity's identity to their public key. The CA digitally signs the certificate, providing authenticity and trust. Anyone who needs someone's public key retrieves it from the certificate, which can be stored in a public directory or transmitted during a session. This ensures the public key is trustworthy and genuinely belongs to the claimed entity.
