Decrypt given data previously encoded with aes128 cipher algo. AES with 128-bit key, a widely used symmetric encryption algorithm. Part of the AES standard defined by NIST in 2001. Considered secure but less resistant to brute-force attacks compared to AES-256. 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.
