Decrypt given data previously encoded with aes-128-cbc-hmac-sha1 cipher algo. AES-128-CBC with HMAC-SHA1 for authentication. Combines AES-128-CBC encryption with SHA-1 HMAC for integrity verification. More secure than AES-128-CBC alone but SHA-1 is considered weak due to collision vulnerabilities. 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.
