LinkedIn hack and password encryption

You might remember the LinkedIn hack of 2012. Their password encryption was extremely poor, and it was easy for anyone who obtained the leaked password files to retrieve the original passwords. At the time it was announced that 6.5 million accounts had been compromised.
