Cipher Forge vs Rounding Unlocked

CipherForge turns secret messages into an adventure. Choose from over a dozen cipher modes, chain them together for maximum mystery, or build your very own personal code in The Forge. CIPHER MODES INCLUDED: - Caesar Cipher: classic letter shift - Vigenere Cipher: keyword-powered encryption - Atbash: ancient A=Z, B=Y reversal - Rail Fence: zigzag message scrambling - Pig Latin: the classic playground code - Morse Code: dots and dashes like a telegraph operator - Substitution: swap every letter with a custom alphabet - Reverse: read it backwards - Number Cipher: replace letters with numbers - Elvish Script: mystical runic encoding - Invisible Ink: hide your message with decoy letters - Levi's Conundrum: alternating number substitution - The Caleb Protocol: swap every pair of letters - The Forge: design your own code where every letter maps to your secret symbol or word THE FORGE Create a completely personal cipher. Assign any word, symbol, or string to each letter of the alphabet, then share your custom codebook with friends so they can decode your messages. CHAIN CIPHERS TOGETHER Build multi-layer codes by stacking ciphers. Vigenere + Rail Fence + Caesar? Your message becomes nearly impossible to crack without knowing the full chain. SHARE WITH FRIENDS Generate a QR code or short text share code for any cipher mode. Friends scan or enter the code to import your exact cipher setup. No accounts needed. MESSAGE HISTORY Every message you encode or decode is saved locally so you can refer back to it later. Clear it any time. COMPLETELY PRIVATE CipherForge works 100% offline. No accounts. No ads. No tracking. No data ever leaves your device. Perfect for kids learning about cryptography, families playing secret message games, teachers introducing code-breaking concepts, and anyone who loves puzzles.
