Sigh.<p>1. Take a hash.<p>2. Start at "aardvark".<p>3. SHA1 the salt + aadvark.<p>4. Compare to the hash.<p>5. Repeat until "zymoscope".<p>It's so weird to me that rainbow tables have so captured people's imaginations that they can't comprehend other attacks to hashes, despite the fact that the brute-force attack I just described was the <i>only way password files were ever cracked</i> for the entirety of the 1990s. It's <i>plenty fast</i>.
