Decrypt given data previously encoded with aes-256-xts cipher algo. AES with 256-bit key in XTS (XEX-based Tweaked CodeBook mode with CipherText Stealing), used for disk encryption. Designed specifically for storage encryption, avoiding patterns in ciphertext. Highly secure for disk encryption but not suitable for data transmission. 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.
