0Excellent video about why the SHA 256 hash algorithm is so cool and useful / Boing Boing
SHA 256 is an algorithm that takes a digital input of any length and returns a string of 256 bits (typically converted to 64 hexadecimal digits). It's a one-way algorithm, which means there's no known way to practically retrieve the input from the output. As far as anyone knows, there has never been an instance of two different inputs having the same output, which means the hash of an input is a reliable unique digital fingerprint.
In this 6-minute video, Matthew Weathers explains why SHA 256 is "useful for digital signatures, cryptography, authentication, and is a central part of the Bitcoin protocol."

When it comes to getting stats and ideas across quickly, there’s still nothing like a good slide presentation. But the critical word here is “good” – not 20 slides all thrown together with the same stock PowerPoint template.
