Cryptographic Key Generation Methodology

This tool generates PGP key pairs using the RSA (Rivest-Shamir-Adleman) public-key cryptosystem following the OpenPGP standard (RFC 4880) with Bouncy Castle cryptographic library.

RSA Key Generation Steps:

  1. Prime Generation: Two large random primes (p and q) generated using CSRNG
  2. Modulus Calculation: n = p ร— q (key size determines bit length)
  3. Totient Function: ฯ†(n) = (p-1)(q-1)
  4. Public Exponent: e = 65537, where gcd(e, ฯ†(n)) = 1
  5. Private Exponent: d โ‰ก eยน (mod ฯ†(n))
  6. Key Packaging: Formatted per OpenPGP standard (RFC 4880) in ASCII-armored output

Frequently Asked Questions

RSA key size determines security strength and computational cost. 1024-bit keys are weak and vulnerable to modern attacks. 2048-bit keys are the current standard, providing strong security with reasonable performance. 4096-bit keys offer maximum security and future-proofing but require more resources. For new keys, use 2048-bit minimum, 4096-bit for long-term sensitive data.
Choose AES-256 for maximum security (256-bit key). AES-192 and AES-128 are also strong. TWOFISH is a good alternative with 256-bit security. BLOWFISH, CAST5, and TRIPLE_DES are legacy - use only for compatibility with older systems.
This tool has zero data retention - keys are never logged or stored. Generation uses CSRNG over HTTPS. For highly sensitive applications, consider offline tools like GnuPG on air-gapped computers.
Save your private key securely (never share it). Share your public key via keyservers (keys.openpgp.org). Test keys using the PGP Encrypt/Decrypt tool. Generate and store a revocation certificate. Verify fingerprints when exchanging keys.
Yes. Keys follow OpenPGP standard (RFC 4880) and are compatible with GnuPG, PGP Desktop, OpenKeychain, Mailvelope, and Thunderbird/Enigmail. Keys are in ASCII-armored format, universally supported.
Use the pgpy library. This tool includes a built-in Python compiler with key generation templates. Click Try It Live in the output panel to generate PGP keys with Python code directly in your browser.
Use at least 16 characters with mixed case, numbers, and symbols. If you forget your passphrase, encrypted data cannot be recovered - there is no backdoor or reset mechanism. Use the built-in passphrase generator for cryptographically secure random passphrases.
