gpg2

Gpg2 is a command line tool used for encrypting and decrypting files, as well as managing encryption keys in Linux. It is an improved version of Gpg (GNU Privacy Guard) and offers enhanced security features. Gpg2 uses the OpenPGP standard for encryption and digital signatures. It supports various encryption algorithms like RSA, DSA, and AES. Apart from file encryption, it also allows encrypting and signing emails and text messages. Gpg2 provides key management functionalities such as generating new keys, importing/exporting keys, and revoking keys. It offers a user-friendly interface for interacting with keys and managing trust relationships. The tool provides options for advanced encryption settings such as setting expiration dates for keys and creating key pairs with multiple subkeys. Gpg2 can be integrated with email clients and other applications for seamless encryption and decryption operations. With its strong encryption capabilities and widespread usage, Gpg2 is a popular choice for secure communication and file handling in the command line.
