Password Calculator

With the Online Password Calculator you may calculate the time it takes to search for a password using brute-force attack under conditions you specify. Read this article to learn more about passwords.

Enter the necessary information and press the 'Calculate' button. Keep in mind that the result you get is the complete search time, i.e., during this time your password will be found with a 100% probability. The probability to find the password during half this time equals 50% and so on. The final number is rounded off and displayed in the most appropriate time units. Precise values are also displayed (rounded off to seconds).

IMPORTANT NOTE: Password Calculator estimates recovery time for Brute-force attack only. Brute-force attack is the worst case, sometimes other more effective recovery methods are available. For example any password-protected Word or Excel document could be recovered using our unique Guaranteed Recovery or Express Recovery within a reasonable time frame.
