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.

📚 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.
