Unkr

unkr is a tool made to decrypt/encrypt using combinations of old school algorithms.

For decryptions I am also developing a bruteforce command.

See examples in documentation. (this README.md is used for tracking progress).

Use Cases

• cargo run -- bruteforce --string STRING --clue clue --clue clue2
• use enhanced / encrypt methods when useful
  • cargo run -- encrypt --string HELLOHELLO -- cut:5 vigenere:KEY:ALPHABET transpose:12 swap:0:5:6:4:2:3:1
• unkr decryptor <decryptor> shows doc for decryptor
• unkr bruteforce --clues-file ./words
• unkr bruteforce-combination --clue clue --string string -- permute:4 vigenere:2:3

Caching

• save combinations in the form ./md5string/md5clues/{hits,done}:
  • hits file line vigenere:ABC:DEF join;RESULT
  • done file line vigenere join cut;vigenere:3:3 (only applying params)
  • (always save in done)
• partial cache
  • Partial BruteForce
    • First I do Permute length=3, then length=5 -> cache applies
  • Partial Checkpoint
    • When using Ctrl + C, write all current permutations to cache as vigenere join cut;vigenere:3:3;partial vigenere:ABC:ALPHABET join cut:3
  • vigenere join cut;vigenere:3:3

Perf

• use a multiproducer channel to get hits ?

  • permutations
• cut message in parts
• print better results (with values)
• finish deserialization for cryptors
• document shit
• harmonize method names
• fix test method names
• perfs monitoring
• multithreading
• [~] profiling
• when a thread is done, reallocate from another
• move to get_next
• read from stdin by default
  • encrypt
  • decrypt
• always test:
  • all cryptors encrypt(decrypt())
  • all cryptors readable
• decryptors docs
• bruteforce finishers?
  • colors
  • join
  • bold
• useless combination (join join)
• NumberArgs -> usize
• Division dispatcher threads
• remove join?
• ASD coin
• numbers in chars ??
• fuzzer rules in CLI params
• use EnumIter everywhere ?
