"I wrote an encryption algorithm with 612 bits of security." (I really like to imagine the 'notes' from the studio on this -- "I like how this establishes that Hansen is a very talented programmer, but let's bump it up 100 to show he was really good.")

"We need Linux servers..." (In the year 2000, he expected the FBI to run its infrastructure on OSS? No wonder this guy got nowhere!)

Other than that, the movie was okay, even if it had the cliched cop-out "Why did he do it? Well, in the end it doesn't matter. He did it. And that's what counts." That may be what counts in the real world, but in a story the 'why' is central to the job.
