§Solitaire Cypher

An implementation of the playing card based cypher created by Bruce Schneier and featured in Neal Stephenson’s “Cryptonomicon”. Includes crate solitaire_cypher_cli for command line usage. See: https://www.schneier.com/academic/solitaire/ and, of course, read Cryptonomicon!

Structs§

  • CypherText
    Container for an ordered collection of UpperLetters intended for use as cyphertext
  • KeyStream
    Container for an ordered collection of UpperLetters for use as a KeyStream
  • Passphrase
    Container for an ordered collection of UpperLetters intended for use as a passphrase
  • PlainText
    Container for an ordered collection of UpperLetters intended as plaintext

Functions§

  • decrypt
    Decrypt CypherText into PlainText using the given KeyStream
  • encrypt
    Encrypt PlainText into CypherText using the given KeyStream. Will panic if KeyStream length is less than PlainText length rounded up to the nearest multiple of 5.
  • get_key_stream
    Create a KeyStream of the specified length from a Card deck
  • key_deck_from_passphrase
    Create a key deck from a Passphrase (aka key). This follows the basic algorithm in that it does not include the “Optional step”.
