Cryptosystems have various challenges that render them vulnerable. Since the cryptosystem ensure data security and integrity, the weaknesses of such systems are very critical. The MD5 SSL has a critical vulnerability in that it is possible for one to create phishing sites that have valid SSL certificates. Such vulnerability is most probable using the HTTPS. In this case, the SSL certificates are made from an existing one using hash collision.
