Protect your sensitive information with GNU Privacy Guard.
GNU Privacy Guard (GPG) is a free software that provides encryption and authentication for your data.
The GNU Privacy Guard (GPG) is a free and open-source software tool that provides encryption and digital signature capabilities. It is developed by the Free Software Foundation and is a replacement for the proprietary software, PGP (Pretty Good Privacy).
GPG uses a combination of symmetric-key and public key cryptography to secure emails, documents, and other sensitive information. Users can create digital signatures to verify the authenticity of messages they send, and can also encrypt messages to ensure their privacy.
GPG is available for multiple operating systems, including Windows, macOS, and Linux. It also has a command-line interface for advanced users and can be integrated with popular email clients such as Thunderbird and Microsoft Outlook.
- Features:
- Strong encryption algorithms such as AES and Twofish.
- Creating digital signatures for messages to verify sender's identity and ensure message integrity.
- Support for public key infrastructure (PKI) to manage keys used for encryption and decryption
- Integration with email clients for secure email transmission.
GPG is widely used by individuals and organizations around the world for secure communication. Its availability as free software means that its users have the freedom to use, modify, and distribute it as they please.
