category.securityFree online PGP encryption/decryption tool based on RSA + AES hybrid encryption, with key pair generation support.
TL;DR:Free online PGP-style encryption tool: RSA-2048 wraps a random AES-256-GCM session key. Powered by Web Crypto API, runs locally — keys never leave your device.
FAQ
Completely free, no registration required. Generate RSA key pairs, encrypt and decrypt messages in your browser — all operations run locally.
The tool uses PGP-style hybrid encryption: RSA-2048 wraps a random AES-256-GCM session key, mirroring OpenPGP’s hybrid encryption philosophy, but the ciphertext format is not fully OpenPGP-compatible.
No. All key generation, encryption, and decryption operations run locally in the browser using the Web Crypto API. The private key never leaves your device.
Not directly. The ciphertext format is a simplified PGP-style format customized for the web and is not compatible with OpenPGP implementations like GnuPG. Both parties should use this tool.
