Decrypt given data previously encoded with aes-256-cbc-hmac-sha256 cipher algo. AES-256-CBC combined with HMAC-SHA256 for authenticated encryption, offering stronger integrity protection. An improved variant over SHA-1-based authentication, widely used in secure communications. Secure and recommended for environments requiring both encryption and integrity verification. 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.
