AES Decrypt: Decrypt Text with Your Key

9 min read

Decrypting AES-encrypted data requires the same secret key that was used to encrypt it. When decryption runs in your browser, your key and data are processed locally and never sent to a server. This guide explains how to decrypt safely and when to use such a tool.

What Decryption Does

You provide the encrypted data (often as base64 or hex) and the secret key. The tool uses the key to reverse the encryption and output the original plaintext. If the key is wrong, the result will be garbage or an error. Only use for data you are authorised to decrypt.

When to Use

  • Recovering your own data: You encrypted something earlier and need to read it again.
  • Authorised access: You have permission and the key to decrypt data from another party.
  • Testing and debugging: Verify that encryption and decryption round-trip correctly.

Do not use to decrypt data you are not allowed to access.

Use Our Tool

Our AES Decrypt tool takes encrypted data and the same secret key and decrypts it. Both steps run in your browser; we never see your key or data. Use only for data you are allowed to decrypt.
