• Key generation. Create PGP key pairs, including public and private keys. The process follows standard security parameters, with options to select the algorithm type, key size, and expiration date. Generated keys can be exported in ASCII-armored or binary format.
• File encryption. Encrypt files using the recipients' public keys. Supports algorithms such as AES, 3DES, and CAST5, ensuring data confidentiality. Encrypted files can be safely sent over unsecured channels.
• File decryption. Decrypt files previously encrypted with PGP. Requires the matching private key and, if the key is protected, its passphrase to access the original content.
• Digital signing. Sign documents digitally to verify their authenticity and integrity. The signature can be attached to the file or saved separately, making later verification easier.
• Signature verification. Check the validity of digital signatures on documents. Confirms the signer's identity and detects any unauthorized changes to the content.
• Key import. Import PGP keys from files or public keyservers. Imported keys can be used to encrypt data or verify signatures.
• Key export. Export public and private keys in various formats. Keys can be shared with other users or backed up for secure storage.
• Key management. An organized system for managing stored keys. Includes functions for editing metadata, revoking keys, and setting trust levels.
• Email encryption. Built-in capabilities for encrypting and decrypting email messages. Compatible with email clients that support the PGP/MIME standard.
• Data compression. Options to compress files before encryption, reducing the size of the transmitted data. Supports algorithms such as ZIP, ZLIB, and BZIP2.
• Passphrase protection. Adds an extra layer of security by requiring a passphrase to access private keys or encrypted files. Uses key derivation techniques to resist brute-force attacks.

PGP Tool was originally developed in 2018 as a cross-platform solution for handling PGP encryption. The project is written in JavaScript using the Electron framework, which allows it to run on Windows, macOS, and Linux. The developers follow a policy of regular updates to introduce security improvements and maintain compatibility with current standards.
