Decrypt given data previously encoded with camellia128 cipher algo. Camellia with a 128-bit key size, offering strong encryption with smaller key sizes. Camellia was developed by Mitsubishi Electric and NTT as an alternative to AES, with a 128-bit variant for strong yet efficient encryption. Camellia-128 is highly secure and considered to be on par with AES-128 for most cryptographic uses. 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.
