How’s your hash generating ability? Not that kind of hash! I’m talking about security hashing. This is essential to cryptography and one aspect you’ll need to know about to acquire your Security+ certification. If you are looking to get your start as a security professional, this is where it all begins. This might be an entry-level certification but you’ll be showing the world that you have an understanding of threat and identity management, security systems, access control and, yes, even cryptography.
