OpenPGP

OpenPGP is a standard for secure communication that uses encryption to protect the privacy of digital messages. It allows users to lock their messages with a public key so only someone with the corresponding private key can unlock and read them. It also supports digital signatures to verify the sender's identity and ensure the message hasn’t been tampered with. OpenPGP is widely used in email security to safeguard sensitive information, ensuring confidentiality, authenticity, and integrity of communications in a reliable and standardized way.
