Frequently Asked Questions

Do I need the same settings used during encryption?
Yes. You must use the exact same AES mode, key size, and key that were used to encrypt the data.
What if I don't know the encryption settings?
You'll need to try different combinations of mode and key size. Without the correct key, the decryption will fail.
