Encryption Methods

• Rivest, Shamir, Adelman (RSA)
  • A well-known public key cryptography system.

• Diffie-Hellman
  • An algorithm for secure private key exchange adapted for public key encryption.

• Data Encryption Standard (DES)
  • This is a very commonly used cryptography system, subject to stringent export control.

• Pretty Good Privacy (PGP)
  • Developed by Phil Zimmerman in 1991.
  • Implements public key cryptography.
  • Implements digital signatures.
  • Later versions can use several different encryption algorithms.

• GNU Privacy Guard (GPG)
  • An open source implementation.
  • Compatible with PGP.
    • They can share key rings.
