Decrypt Text recovers the original message from text protected with Encrypt Text. Paste the ciphertext, enter the same passphrase, and the plain text appears as soon as the two match. The current format (AES-256-GCM with a PBKDF2-SHA-256 key) is recognised by its version prefix, and older CryptoJS-style AES strings, which begin with U2FsdGVkX1, are accepted too. Because GCM is authenticated, a wrong passphrase or an edited ciphertext produces an error instead of garbled text. Decryption runs on your device, so neither the passphrase nor the message leaves the browser.
Paste the protected text
Paste the whole ciphertext into Protected text, including the prefix at the start.
Enter the passphrase
Type the exact passphrase used to encrypt it. Passphrases are case-sensitive, and the result updates as you type.
Copy the plain text
When the passphrase matches, the original appears under Recovered plain text. Press Copy plain text to use it.
Usually the passphrase is wrong (it is case-sensitive) or the ciphertext was cut short or changed while being copied. Make sure you pasted the full string with nothing added or missing.
No. The key is derived from the passphrase, so the only alternative is guessing, which is impractical against a long, random passphrase.
No. It reads the format created by Encrypt Text and the CryptoJS passphrase format. Ciphertext from tools that use a raw key, a different mode or another layout will not decrypt here.
Yes. Decrypt Text is completely free, with no account, no paywall, and no usage limits.
No. Decrypt Text works instantly in any modern web browser — there is no software to install, no extension, and no sign-up.
