What the site is for
The project pairs interactive tools with plain-English articles so learners can try a cipher, inspect the steps, and then read the explanation in the same place.
About
About CipherRegister
CipherRegister is a browser-based reference for classical ciphers, encodings, signalling systems, and cryptanalysis basics.
How the tools work
Tools run in the browser where possible, avoid account requirements, and are built for education, puzzles, and historical interest rather than real secrecy.
What to remember
Classical ciphers are useful for learning patterns, keys, grids, and attacks, but they should not be used for passwords, private messages, API keys, or sensitive data.
