Passphrase Strength Analyser

Features

  • Passphrases analysed using this Java Applet never leave your computer.
  • A dictionary of all words in the English language is used to analyse your passphrase for weakness.
  • This tool quotes an estimate on the number of days such a password is safe for.

Please Note

  • A typical home computer can attempt over 400,000 passwords per second.
  • A typical hacker will use many computers to gain access to your files, servers and email accounts.
  • For user-friendly reasons, this tool currently only checks English words. An attacker would try many more languages with little to no effort.
  • Contact us if you would like to purchase this tool.

Recommendation

CertainKey recommends the following to create a strong passphrase. Your passphrase should:
  • not be based on an English word,
  • contain at least 3 lower-case letters,
  • contain at least 3 upper-case letters,
  • contain at least 2 decimal digits,
  • be at least 8 characters in length, and
  • be sufficiently random (ie. a Binary Signal Entropy greater than 3)

Examples

Meeting these conditions will dramatically increase the time required for a hacker to guess your password.

The passphrase "runspotrun" does not meet these conditions. A computer would crack it in less than 1 day. The passphrase "Yg0rH8oK" does meet all the conditions mentioned above and would require over 500 days to crack!
