Cipher Stack Lab 2.0

20+ reversible transformations · one-click mode · works offline

⚡ Quick Encrypt

Paste any message and hit one button. Quick mode chooses a ready-made three-layer recipe. It remembers the recipe inside a shareable package so decryption is easy.

Paste an encrypted package in the top box to decrypt it.

🧪 Cipher Stack Builder

Add as many layers as you want. Encryption goes from top to bottom; decryption automatically runs them in reverse. The app uses UTF-8 bytes internally, so it never needs to change your actual words.

How it works

Smart text preparation converts your input into a reversible UTF-8 byte representation. That means no words are silently replaced, and the exact original text comes back when you decrypt. The displayed encrypted result is Base64URL, making it easy to copy or send. Base64 alone is encoding, not strong encryption.

Self-contained packages include the message and recipe settings, so whoever receives one can decrypt it in this app without manually rebuilding the stack. Because recipes and keys are included, packages are for games, not private secrets.

⚠️ Educational puzzle ciphers only. Do not use these for passwords, financial details, or sensitive messages.
