ENCRYPT MESSAGE

How it works

The outer ring (A–Z) is the plaintext alphabet. The inner ring (a–z) is the ciphertext. Spinning the inner disk shifts the substitution — each position creates a unique cipher key.

⚠ For fun only

This tool does not capture any text you type — but never enter seed phrases or passwords. Download the key and work it out offline. For stronger encryption, change keys every few words.
