Cryptography - Coggle Diagram

- - - - block cipher
      - 56 bit key
      - 64 bit block size
      - insecure, superseded by AES
    - - block cipher
      - 168 bit key
      - more effective than DES, but much slower
    - - block ciper
      - 128, 192, or 256 bit keys
      - replaces DES, much faster than both of them
    - - lost to AES in encryption contest
      - RC2-RC6
    - - block cipher
      - 64 bit block size
      - 32 to 448 bit key
      - insecure :unamused:
    - - block cipher
      - 128 bit block size
      - 0-256 bit key
  - - - one of most common encryption for data transmission
    - - used for EXCHANGING keys
      - generates shared key between 2 people over insecure channel
    - - uses points on elliptical curve
    - - signature verification (integrity)
    - - encryption and digital signatures
      - logarithmic
