All PGP file encryption and decryption is performed locally in your browser. Files, messages, and keys are never transmitted to any server.
PGP file encryption is a secure method for protecting files using public-key cryptography. Files are encrypted with one or more PGP public keys, ensuring that only intended recipients holding the corresponding private keys can decrypt and access the data. This makes PGP ideal for sharing sensitive files over email, cloud storage, or external drives.
PGP uses a hybrid encryption approach. Your file is encrypted using a fast symmetric algorithm, while the symmetric key itself is encrypted with the recipient’s public key. This allows PGP to efficiently encrypt large files while maintaining strong security guarantees.
While RSA encryption is suitable for encrypting small text or secrets, it is not designed for encrypting large files directly. PGP combines RSA with symmetric encryption, making it far more practical and secure for file encryption use cases.
| Feature | PGP File Encryption | RSA Encryption |
|---|---|---|
| Large file support | Yes | No |
| Multiple recipients | Yes | No |
| Hybrid encryption | Yes | No |
| Recommended for file sharing | Yes | Limited |
All PGP file encryption and decryption operations are performed entirely within your browser using OpenPGP.js. Your files, keys, and passphrases are never uploaded, stored, or logged on any server, ensuring complete privacy and security.
