Password Cracking Time Calculator

Change options below to see cracking times for different cracks per second (variations in computer speed and hashing method), different size character sets, and different password lengths. If you are only interested in strong passwords, you might remove the smaller character set sizes or any lengths less than 10. Times are for processing all character combinations; average time for a specific password would be one half the listed time, but could vary from a fraction of a second to the full listed time. Any weakness, such as similarity to any common password, known names and words, or common phrases, invalidates all times as they apply only to pure brute force attacks.
