OpenPGP standard

The OpenPGP standard is a set of rules and protocols for secure communication, allowing people to encrypt (hide) and sign their digital messages or files. It uses a system called public-key cryptography, where each person has a pair of keys: a public key (shared openly) and a private key (kept secret). When someone encrypts a message with your public key, only you can decrypt it with your private key. Signing a message verifies the sender’s identity and ensures the message hasn’t been altered. OpenPGP helps keep online exchanges private, authentic, and tamper-proof.
