GnuPG 1.4

GnuPG (GNU Privacy Guard) is a free and open-source software implementation of the OpenPGP (Pretty Good Privacy) standard for encrypting and signing data. It allows users to securely communicate and protect sensitive information.

Yes, GnuPG is compatible with PGP (Pretty Good Privacy), another widely used encryption software. GnuPG follows the OpenPGP standard, which ensures interoperability between different implementations.

GnuPG uses asymmetric encryption, where users have a pair of cryptographic keys: a public key for encryption and a private key for decryption. The sender encrypts the data with the recipient's public key, and only the recipient, with their corresponding private key, can decrypt and access the information.

Yes, GnuPG can be used to encrypt files as well as emails. It provides command-line tools that allow users to encrypt, decrypt, and verify the integrity of files using their keys.

Yes, GnuPG is available for various operating systems, including Linux, macOS, Windows, and also has mobile versions for Android and iOS.

GnuPG utilizes strong cryptographic algorithms and follows best practices to ensure security. However, like any encryption software, its overall security depends on proper key management, secure passphrase usage, and regular software updates.

Yes, GnuPG supports digital signatures. Users can sign files or emails to authenticate their identity, prevent tampering, and verify that the content hasn't been altered since being signed.

Yes, there are several graphical user interfaces (GUIs) available for GnuPG, such as Gpg4win and GPGTools, which provide a more user-friendly way to manage keys, encrypt/decrypt files, and handle encryption tasks.

Yes, GnuPG can be used for securing communications over the internet. By encrypting emails or other forms of communication, users can ensure their privacy and protect the confidentiality of sensitive information during transmission.

Yes, GnuPG is free and open-source software released under the GNU General Public License (GPL). It can be freely downloaded, used, modified, and distributed.
