Decryption is the process of converting encrypted or encoded data back into its original form so
it can be understood. Using cryptographic keys, decryption tools ensure that only authorized
users can access the original message. This decryption tool allows you to decrypt AES-encrypted
data back into plain text using AES-GCM or AES-CBC algorithms.
How to Use the Decryption Tool
Select the appropriate decryption algorithm (AES-GCM or AES-CBC) that matches the encryption
method used.
Enter the key and initialization vector (IV) that were used during encryption in the
respective fields.
Paste the encrypted text into the "Encrypted Text" box.
Click the "DECRYPT" button to reveal the original plain text in the "Decrypted Text" field.
Why Use AES Decryption?
Decryption ensures that encrypted data is accessible only to authorized individuals who possess
the correct key and IV. AES decryption is widely trusted in industries like finance, healthcare,
and government to securely decode sensitive information. This tool allows you to quickly decrypt
AES-encrypted messages back to their original form.
Frequently Asked Questions
Which AES modes are supported?
This page supports AES-GCM and AES-CBC.
Do I need the same encoding used during encryption?
Yes. The key, IV, and ciphertext encoding must match the original Base64 or Hex format.
