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!
