§Unkr decrypt and bruteforce old school cyphers

Encrypt and Decrypt strings using old school cryptography, like Vigenere, Transposition, and more.
Bruteforce challenges when knowing a part of the clear text.
Print out all possible strings and look for words inside yourself.

§Decrypt/Encrypt Examples

§Basic

$ echo "ABCDEF" | unkr encrypt -- transpose:2
ACE
BDF

§Kryptos panel K1

$ echo "EMUFPHZLRFAXYUSDJKZLDKRNSHGNFIVJYQTQUXQBQVYUVLLTREVJYQTMKYRDMFD" | unkr decrypt -- vigenere:PALIMPSEST:KRYPTOS

§Kryptos panel k2

(passing string as argument instead of stdin)

$ unkr decrypt --string 'VFPJUDEEHZWETZYVGWHKKQETGFQJNCEGGWHKK?DQMCPFQZDQMMIAGPFXHQRLGTIMVMZJANQLVKQEDAGDVFRPJUNGEUNAQZGZLECGYUXUEENJTBJLBQCRTBJDFHRRYIZETKZEMVDUFKSJHKFWHKUWQLSZFTIHHDDDUVH?DWKBFUFPWNTDFIYCUQZEREEVLDKFEZMOQQJLTTUGSYQPFEUNLAVIDXFLGGTEZ?FKZBSFDQVGOGIPUFXHHDRKFFHQNTGPUAECNUVPDJMQCLQUMUNEDFQELZZVRRGKFFVOEEXBDMVPNFQXEZLGREDNQFMPNZGLFLPMRJQYALMGNUVPDXVKPDQUMEBEDMHDAFMJGZNUPLGEWJLLAETG' -- 'vigenere:ABSCISSA:KRYPTOS'

§Kryptos panel k3

There is some confusion here between encrypt and decrypt, I need to fix the right verb but I am not sure about what to for transpose actually.

Also symbols are totally ignored.

§Cryptors

Current cryptors are

assert_eq!(cryptors,  vec![
       BruteForceCryptor::Vigenere(BruteForceVigenereArgs { // [...]
       }),
       BruteForceCryptor::Cut,
       BruteForceCryptor::Caesar,
       BruteForceCryptor::Transpose,
       BruteForceCryptor::AtBash,
       BruteForceCryptor::Reverse,
       BruteForceCryptor::Swap,
       BruteForceCryptor::Join,
       BruteForceCryptor::Permute(BruteForcePermuteArgs { // [...]
       }),
   ]);

§Bruteforce

The second interesting feature is bruteforcing using clues.

cargo run -- bruteforce --decryptors enigma --string ILBDARKFH --clues HELLOTEST --threads 16
