Cryptography and coding theory with MAPLE page

• Applied abstract algebra course page
• Prof. Wardlaw's Cryptology and Number Theory Course Page
• Gray codes
• Golay codes
• MAPLE worksheet (in html form) for basic routines on cyclic, binary Hamming, and Golay codes (as well as some string-theoretic commands). An updated version of the corresponding MAPLE worksheet codes0.mws and MAPLE package codes.mpl is explained in cyclic, binary Hamming, and Golay codes. Written by D Joyner, 1998, updated 2001.
• MAPLE exercises in coding theory,
• GAP exercises in coding theory,
• MAGMA exercises in coding theory,
• MAPLE worksheets for basic routines in cryptography:
  • basic string-theoretic commands useful for decoding "classical" encryptions (this uses the text file paradise_lost.mpl)
  • random stream encryption using MAPLE's random number generator
  Corresponding MAPLE package crypto.mpl. Written by D Joyner, 1998.
