PGP Key Generator & Inspector – Create and Analyze OpenPGP Keys Online

This PGP key generator and inspection tool allows you to create secure OpenPGP key pairs and analyze existing public or private PGP keys directly in your browser. All cryptographic operations are performed client-side, ensuring privacy, transparency, and security.

Whether you are setting up PGP encryption for email, encrypting files, or validating third-party keys, this tool helps you manage and understand PGP keys without installing additional software.

PGP Key Generation (Client-Side)

The PGP key generator enables you to create strong and modern OpenPGP public and private key pairs using secure defaults. Generated keys can be used for message encryption, file encryption, and digital signatures.

  • Key Size Selection: Choose RSA key sizes (2048, 3072, 4096 bits) based on your security needs
  • Passphrase Protection: Encrypt private keys with a passphrase for additional security
  • Key Expiry: Define an expiration date to limit key lifetime and reduce long-term risk
  • ASCII Armored Output: Export keys in standard -----BEGIN PGP KEY BLOCK----- format
  • Browser-Based: Keys are generated locally and never leave your device

Generated public keys can be safely shared with others, while private keys should be kept secure and protected by a strong passphrase.

PGP Key Inspection & Analysis

The PGP key inspection feature allows you to parse and analyze existing OpenPGP keys to verify their authenticity and cryptographic strength.

  • Key Type Detection: Automatically identifies public vs private keys
  • Algorithm: RSA, EdDSA (Ed25519), ECDH, and other supported OpenPGP algorithms
  • Key Strength: Displays RSA key size or elliptic curve details
  • Fingerprint: Full OpenPGP fingerprint for secure verification
  • Key ID: Derived primary key ID
  • Creation & Expiration: Shows key creation time and expiry status

Why PGP Key Generation and Inspection Matter

Proper PGP key management is critical for secure communication. Generating strong keys and regularly inspecting them helps ensure:

  • Protection against weak or deprecated cryptographic settings
  • Verification of key ownership using fingerprints
  • Compliance with security best practices
  • Safer encryption for messages, files, and digital signatures

Privacy-Focused & Secure by Design

This tool operates entirely in your browser using modern JavaScript cryptography. Your private keys, passphrases, and generated data are never uploaded, stored, or logged. This makes it ideal for learning, testing, and real-world validation.

PGP vs RSA Encryption – What’s the Difference?

PGP and RSA are often mentioned together, but they serve different purposes in modern cryptography. Understanding the difference helps you choose the right approach for secure communication.

Aspect PGP (Pretty Good Privacy) RSA Encryption
Type Complete encryption system (hybrid cryptography) Public-key encryption algorithm
Purpose Secure messages, files, and digital signatures Encrypt small data or exchange secret keys
Algorithms Used RSA / ECC + AES + SHA RSA only
Data Size Supports large messages and files Limited by key size
Key Management Uses key pairs, passphrases, and expiration Uses raw public/private key pairs
Real-World Usage Email encryption, file security, signing Key exchange, certificates, TLS

In practice, PGP often uses RSA internally for key exchange and digital signatures, while symmetric algorithms like AES are used for encrypting the actual data. This hybrid approach makes PGP secure and efficient.

Tip: Use PGP for real-world secure communication. Use raw RSA encryption mainly for educational or low-level cryptography testing.

If you need direct algorithm-level encryption for learning or testing, you can also try the RSA Encryption Tool on Devglan .
