Crack any cipher, encrypt anything, and train your brain with daily puzzles. CipherKit is a complete cryptography lab, codebreaking toolkit, puzzle game, and encrypted vault that works fully offline. SOLVE UNKNOWN CIPHERTEXT Paste, type, or scan a message and let CipherKit figure it out: • Auto-detects the likely cipher and recovers the key • Solvers for Vigenère, Beaufort, Gronsfeld, monoalphabetic substitution, affine, rail fence, and columnar transposition • Interactive Substitution Workbench: tap letters to map them, lock what you know, auto-fill by frequency, or let the hill-climbing solver finish • Frequency analysis and index of coincidence in five languages • Recognizes Base64, hex, binary, URL, and decimal encodings • Honest results when text looks like modern encryption • Save sessions with notes and come back later ENCRYPT WITH 48 CIPHERS From antiquity to the present day: • Substitution: Caesar, ROT13, Atbash, Affine, Keyword, Baconian, Homophonic • Polyalphabetic: Vigenère, Beaufort, Autokey, Running Key, Gronsfeld • Transposition: Rail Fence, Columnar, Scytale, Route • Polygraphic: Playfair, Two-Square, Four-Square, Bifid, Trifid, Hill, ADFGX, ADFGVX, Nihilist, Polybius • Machines: Enigma, M-209, Jefferson Disk • Stream: RC4, ChaCha20, Salsa20, One-Time Pad, Vernam, LFSR • Block and AEAD: AES, DES, Blowfish, Twofish, Camellia, AES-GCM, ChaCha20-Poly1305 • Public key: RSA and Diffie-Hellman demonstrations • Morse code and Tap Code, with audio playback WATCH CIPHERS WORK Animated visualizers show every step: rotating Caesar rings, the Vigenère tabula recta, rail fence zig-zags, Playfair grids, columnar read-offs, Enigma rotors stepping, and Morse timelines.
