If someone sent you a link, a block of encrypted text, or a .txt file from this site's Encrypt Text tool, here's how to read it. Decryption happens entirely in your browser using the password you were given; nothing is uploaded anywhere in the process.
By design, content is never decrypted automatically on page load, even if the password was included in the link. This avoids the secret appearing on screen without you choosing that moment, for example if the link opens in a background tab. Click "Reveal" to see it.
Either the password is wrong, or the encrypted text or file was altered or copied incompletely. The two cases look identical by design, since encryption that could tell them apart would leak information about the password itself. Double check the password and that you copied the full encrypted text.
No. Decryption happens entirely in your browser. The encrypted text, the password, and the decrypted result never leave your device.
