Our team developed a system which enable user identify cryptographic function in blockchain system. By allowing users to upload their code through online input box, a file upload or a repository link, they can make use of our web application to scan through their code and check is there any known exploits found in the cryptographic functions. With the help of our system, users able to fix the problem found, as well as learn new ways on how to keep their code more secure. Thus, it may help users updated on the latest blockchain system and cryptography news and updates.
