GnuPG
OpenPGP standard implementation for email and file encryption, signing, and key management.
GnuPG (GPG) is the free implementation of the OpenPGP standard, providing cryptographic privacy and authentication for email, files, and code signing. It's the backbone of PGP email encryption, Git commit signing, and Linux package verification. GnuPG supports RSA, ECC, and Ed25519 keys, and integrates with email clients (Thunderbird + Enigmail, KMail) and developer workflows (git, apt, rpm). It's command-line-first but has GUI wrappers like Kleopatra and GPG Suite for macOS.
