About CipherPad

CipherPad is not CryptPad, and not the GitHub project

Worth clearing up first, because the name is crowded. This site, cipherpad.dev, is not connected to any of the following, and has no shared code, authorship or ownership with them:

• CryptPad, the end-to-end encrypted collaborative office suite. Similar name, entirely different thing: CryptPad is real encryption for real documents.
• Cipherpad on GitHub, an encrypting text editor for Windows that happens to share the name.
• Any product or service offering actual encryption. Nothing here protects anything. Every scheme on this site is either a public encoding or a historical cipher that modern computers break instantly, and each translator says so on its own page.

What this site is: 21 browser-based translators, a cipher identifier for messages you cannot read, printable reference charts, a methodology page stating which variant of each cipher is implemented, and a free JSON API. It is built and maintained by FusionStudios, a web studio in the Netherlands.

Why it exists

Most cipher tools online cover a single code, bury it under adverts, and give you a text box with no explanation. If you are learning, that is frustrating. If you are decoding a puzzle, it is slow. CipherPad brings 21 ciphers and codes together in one clean, fast place, and gives every one a proper page: a working translator, a real chart, worked examples, history and a genuine FAQ.

How it works

Every translator runs entirely in your browser using plain web technology. Nothing you type is uploaded to a server, which is why it is instant and completely private. There is no sign up, no limit, no tracking of your text and no catch.

Who it is for

Puzzle solvers, escape-room designers, geocachers, ham radio learners, teachers looking for printable charts, students meeting cryptography for the first time, and anyone who has ever wanted to write a note in Morse or spell a word in braille. The free API and the embeddable widget are there for developers too.

Accuracy

The maps and rules follow the standard forms: International Morse code, 8-bit ASCII binary, Grade 1 braille, the modern NATO phonetic alphabet, and the classic textbook definitions of the Caesar, Vigenere, Atbash and pigpen ciphers. Several of these have more than one variant in circulation, and where they do, the methodology page states exactly which one is implemented and what happens to characters that cannot be mapped. If you spot something to improve, the contact page is open.
