Generate PGP key pairs, encrypt & decrypt messages, sign & verify text — entirely in your browser. Your private keys never leave your device.
🔑 Generate a New Key Pair
All key generation happens locally in your browser using the OpenPGP.js library. Nothing is sent to any server.
Save to Key Ring (local storage)
✅ Key Pair Generated
Keep your private key and passphrase secret. Anyone with both can read your encrypted messages and impersonate you. These keys were generated locally on this device and were never sent to any server. Download and back them up now — they cannot be recovered later.

🗝️ Your Key Ring
Keys are stored in your browser's local storage. They never leave your device. Export and back up your private keys — clearing browser data will delete them.

📚 How PGP Encryption Works
PGP (Pretty Good Privacy) uses public-key cryptography to secure messages. Each person has two keys:
Public Key — Share freely. Others use it to encrypt messages to you and verify your signatures.
Private Key — Keep secret. You use it to decrypt messages and create digital signatures.
Quick Start
Generate a key pair in the Generate Keys tab.
Share your public key with contacts.
Encrypt messages using the recipient's public key.
Decrypt messages sent to you with your private key + passphrase.
Sign messages to prove they came from you.
Verify signatures to confirm the sender's identity.
Key Types
ECC (Curve25519) — Modern, fast, small keys. Recommended for most users.
RSA 2048 — Good compatibility with older software. Minimum recommended strength.
RSA 3072 — Stronger. Recommended by NIST for use beyond 2030.
RSA 4096 — Maximum strength. Slower key generation but most secure RSA option.
Security Tips
Use a strong, unique passphrase for your private key.
Back up your private key securely — if you lose it, encrypted messages are gone forever.
Verify key fingerprints out-of-band (e.g., in person or via phone) to prevent impersonation.
Set an expiry date on your keys so compromised keys eventually stop working.
This tool runs entirely in your browser — your keys and messages are never transmitted.
How to Use This Tool
Generate a key pair — Go to the Generate Keys tab, enter your name, email, and a strong passphrase, then choose ECC or RSA and click Generate.
Share your public key — Copy your public key and give it to anyone who needs to send you encrypted messages.
Encrypt a message — Switch to the Encrypt tab, paste the recipient's public key, type your message, and click Encrypt.
Decrypt a message — Go to the Decrypt tab, paste the encrypted block, enter your private key and passphrase, then click Decrypt.
Manage keys — Use the Key Ring tab to save, import, and organize your keys locally in your browser.
Common Use Cases
How do I send encrypted email? Generate a PGP key pair here, share your public key with contacts, and use the Encrypt/Decrypt tabs to secure message contents before sending.
How do I verify a digitally signed message? Go to the Verify tab, paste the signed message and the sender's public key, then click Verify to confirm authenticity.
How do I create PGP keys without installing software? This browser-based tool generates standard OpenPGP keys (ECC or RSA) entirely client-side — no GPG installation needed.
