What is a Hash and why should I care?

Wednesday, January 21, 2009 - 9:00am - 10:00am

You may have heard of MD5 or SHA1 hashes but what do hash values really mean? Why should you care if a hash value matches? We will cover the difference between the two hash algorithms (in a very non-mathematical way) and what those hash values mean for integrity of a file. We will also talk about how some anti-virus vendors use hashes to determine malware (as shown in VirusTotal and SecCheck reports). We will also show you how to create/check hash values for programs that you have downloaded. This is especially important if you download any open source software packages.
