Early last year, password security researcher Kevin Young was hitting a brick wall. Over the previous few weeks, he made steady progress decoding cryptographically protected password data leaked from the then-recent hack of intelligence firm Stratfor. But with about 60 percent of the more than 860,000 password hashes cracked, his attempts to decipher the remaining 40 percent were failing.

Almost immediately, a flood of once-stubborn passwords revealed themselves. They included: "Am i ever gonna see your face again?" (36 characters), "in the beginning was the word" (29 characters), "from genesis to revelations" (26), "I cant remember anything" (24), "thereisnofatebutwhatwemake" (26), "givemelibertyorgivemedeath" (26), and "eastofthesunwestofthemoon" (25).
