Secret Message Generator
Encrypt and decrypt messages entirely in your browser using AES‑GCM (with PBKDF2). Share the result as a Secret Message and decrypt it here using the same Secret Code. We don’t store your data.

How it works
This tool derives an encryption key from your Secret Code using PBKDF2 with SHA‑256, then encrypts your text with AES‑GCM in your browser. It authenticates a context string so decryption only succeeds with the same tool context. Your Secret Code is never included in the Secret Message unless you explicitly choose to include it in the share link.
Tips
- Use the generator to create a strong code and keep it private.
- Default output is ASCII/Base64URL for robustness. “Math” and “Emoji” styles are cosmetic and reversible.
- If decryption fails, check the style, the full Secret Message, and the exact code.
