Decrypt given data previously encoded with aes-128-xts cipher algo. AES-128 in XEX-based Tweaked CodeBook mode with ciphertext stealing. Primarily used for disk encryption to mitigate ciphertext pattern leaks. Secure for disk encryption but not suitable for general data encryption due to its design constraints. Our decryption process assumes the IV string is prepended in the encoded string during the encryption process. You can not decrypt and get the correct results if the IV or passphrase mismatch occurs between encryption and decryption process.
