What is new on CipherPad, newest first.

Cipher identifier, code breaking, and honest security labelling 5 August 2026

  • New cipher identifier at /identify. Paste a message you cannot read and it ranks the most likely schemes, with the reasoning for each. It reads the character set first, then falls back to letter statistics (index of coincidence, chi-squared, Kasiski) for anything in ordinary letters.
  • The Caesar page now shows all 25 shifts at once, with the most likely one marked and its score shown, so you no longer need the key to read a Caesar cipher. It also gained the alphabet chart it was missing.
  • The Vigenere page can now recover the key from the ciphertext alone, showing every step: the index of coincidence per candidate key length, the repeated sequences Kasiski finds, and the recovered key.
  • Every translator now carries a permanent notice saying plainly what it is: a public encoding that conceals nothing, a keyless puzzle cipher, or a historical cipher that modern computers break instantly. None of them protects anything, and the site now says so on every page rather than burying it in an FAQ.
  • New methodology page at /methodology stating exactly which variant of each cipher is implemented and what happens to characters that cannot be mapped, so a disagreement with another tool can be explained rather than guessed at.
  • The privacy policy now describes what the site actually does. It previously mentioned advertising networks, analytics cookies and a consent banner, none of which exist. It also explains how to verify the privacy claim yourself in the browser's Network tab.
  • The embeddable widget now works. It was rendering as an empty page with no visible content and no credit link, so every embed passed on nothing. It also grew from 2 translators to 13, and /embed has a snippet generator with a live preview.
  • Guides now show who wrote them and when, and the pages making checkable historical claims have a sources section.
  • The free JSON API grew from 7 endpoints to 11, gained an explicit CC BY 4.0 licence, and now states the standard behind each map. New: pigpen, Polybius, Bacon and a Morse timing table.
  • Every translator page now shows a worked example in its initial HTML, so the site demonstrates what it does before you type anything.

Launch 2 July 2026

  • 15 working translators: Morse, binary, text to binary, binary to text, braille, Caesar, ROT13, Atbash, Vigenere, Pig Latin, leetspeak, A1Z26, tap code, NATO phonetic and Base64 text.
  • Pigpen cipher page with a full visual symbol chart.
  • 15 reference guides covering Morse, binary, braille, the NATO alphabet, classic ciphers and the Zodiac ciphers.
  • The ultimate cipher and code reference mega-page with every chart in one place.
  • Morse audio playback with adjustable timing.
  • Free static JSON API and an embeddable translator widget.
