SHA-1 Competition

Engineyard posted a programming contest on July 14, 2009. The task was to find a phrase whose SHA-1 hash has minimal Hamming distance from the SHA-1 hash of a target phrase. To make things more interesting, the phrases were restricted to words from a 1000-word dictionary, had to consist of 12 words with spacing, and could be followed by at most 5 (free) printable ASCII characters. The words could have upper and lowercase letters at any position. Time: 30 hours after start.
The contest started on July 20, 2009 when the target phrase and contest dictionary were posted.
