About PGP Cryptography
Key Concepts:
  • Public Key: Shared openly, used to encrypt messages TO you
  • Private Key: Kept secret, used to decrypt messages FOR you
  • RSA 2048: Strong encryption algorithm and key size
  • Key Rule: Encrypt with recipient's public, decrypt with your private
Security Features:
  • Confidentiality: Only intended recipient can read
  • Authenticity: Verify sender identity
  • Integrity: Detect message tampering
