Decrypt given data previously encoded with camellia-192-ecb cipher algo. Camellia in 192-bit key size with ECB mode, which encrypts each block independently. Like other Camellia modes, ECB mode is included for simplicity, though its security issues are well-known. ECB is insecure due to its lack of diffusion, making it unsuitable for most applications. 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.
