Explanation
Pretty Good Privacy (PGP) is a widely used encryption method for securely exchanging public keys and encrypting communications between users. PGP uses a web of trust model or certificate authorities to authenticate public keys and ensure they are not tampered with. - Hardware Security Module (HSM) is used for key storage and cryptographic operations, not key - Automated Certificate Management Environment (ACME) is primarily used for automating TLS certificate issuance, not public key exchange between individuals. - Secure Multipurpose Internet Mail Extensions (S/MIME) is used for encrypting and signing emails but does not focus on public key exchange as its primary function.
