Adds one line to the Links list, alphabetically between Talos Intelligence and Threat Fox.

Text Machine is a free, fully client-side cipher toolkit. The linked page is the cipher identifier: you paste unknown ciphertext and it runs character-set checks, Index of Coincidence, and chi-squared shift tests to rank the likely ciphers, then decodes the message inline for anything that needs no key (Morse, binary, Base64, hex, Baconian, Polybius, A1Z26, ASCII, Atbash, Caesar). For the two that need a search there are auto-solvers that recover the plaintext without a key: Vigenere (Kasiski + IoC key-length, then per-column frequency) and monoalphabetic substitution (simulated annealing on trigram fitness).

Behind it are ~31 classical cipher encoders/decoders, including several that are hard to find elsewhere (Bazeries, Chaocipher, Straddling Checkerboard, VIC, M-94, Trithemius, Porta), plus frequency analysis and Kasiski examination tools.

Everything runs in the browser, so ciphertext is never uploaded. No signup, no ads.

Relevant to this list because it sits alongside the dCode and Morse decoder entries already here, and covers the "I have a blob of mystery text and no idea where to start" case those do not.

Disclosure: I built it.
