  1. A substitution cipher replaces each letter of the plaintext with a letter found by moving [latex]n[\/latex] places down or up the alphabet. Example: Using a shift of 3, \"ABC\" becomes \"DEF.\"<\/li>\n \t
  2. A transposition cipher rearranges the letters of the plaintext. Example: \"HELLO\" can become \"HLELO.\"<\/li>\n \t

  5. Key distribution problems, Susceptibility to brute-force attacks.<\/li>\n \t
  6. Faster encryption\/decryption, Simpler algorithms.<\/li>\n \t
