About PGP/GPG Key Generator
PGP (Pretty Good Privacy) and GPG (GNU Privacy Guard) are encryption programs that provide cryptographic privacy and authentication. This tool generates OpenPGP-compatible key pairs for secure email communication, file encryption, and digital signatures.
Email Encryption
Secure end-to-end encrypted email communication
Digital Signatures
Verify authenticity and integrity of messages
File Encryption
Protect sensitive files and documents
OpenPGP Standard
Compatible with GPG, Thunderbird, and other tools
What is PGP Encryption?
PGP encryption is a method of protecting data through cryptographic techniques. It uses a combination of symmetric and asymmetric encryption to secure communications. When you generate a PGP key pair, you create two mathematically linked keys: a public key for encryption and signature verification, and a private key for decryption and signing.
Common Use Cases for PGP Keys
- Secure Email: Encrypt emails so only the intended recipient can read them
- Code Signing: Sign software releases to verify authenticity
- Document Signing: Digitally sign important documents
- Password Managers: Encrypt password database files
- Git Commits: Sign commits to verify developer identity
- Secure Messaging: Exchange encrypted messages with contacts
- File Protection: Encrypt sensitive files before cloud storage
How to Use This PGP Key Generator
- Enter your full name and email address (this identifies your key)
- Set a strong passphrase to protect your private key (highly recommended)
- Choose your key size (4096 bits recommended for best security)
- Select an expiration period (keys should expire for security)
- Click "Generate PGP Key Pair" and wait for generation
- Download or copy both keys and store them securely
- Share your public key with people who need to send you encrypted messages
- Keep your private key absolutely secret and backed up safely
Understanding Key Components
- Public Key: Share this freely. Others use it to encrypt messages to you and verify your signatures
- Private Key: Keep this secret. Use it to decrypt messages and sign documents
- Passphrase: Protects your private key from unauthorized use if stolen
- Revocation Certificate: Used to invalidate your key if compromised
- Key Fingerprint: Unique identifier to verify key authenticity
Key Size Selection Guide
- 2048 bits: Minimum recommended size, faster generation and operations
- 4096 bits: Recommended for maximum security and long-term use
Best Practices for PGP Keys
- Always use a strong, unique passphrase for your private key
- Store your private key in multiple secure locations (encrypted backups)
- Never share your private key or passphrase with anyone
- Generate and store a revocation certificate immediately
- Set an expiration date and renew keys periodically
- Verify key fingerprints through multiple channels before trusting
- Use key signing to build a web of trust
- Keep your system secure and malware-free when using keys
Publishing Your Public Key
After generating your PGP key, you can publish your public key to keyservers like keys.openpgp.org, keyserver.ubuntu.com, or pgp.mit.edu. This allows others to easily find and use your public key. You can also include it in your email signature, on your website, or share it directly with contacts.

Security Considerations
While this tool generates valid PGP keys using browser cryptography APIs, for production use or highly sensitive applications, consider using dedicated PGP software on a secure, offline computer. Always verify the integrity of any cryptographic tools you use and follow security best practices.
