This application was designed to analyse your password and give it a score depending on its strength. It first compares it to all known common passwords and then the repetiion of letters close to each other which will make the password easy to crack.

A good password should be a minimum of 8 characters long, should include a upper case, lower case, symbols and numbers. A password should ot contain any thing that can be associated with you such as name, birthday and relatives.

Please note that this is a dynamic function which runs in your browser and does not send or store any information you enter. In addition, please remember that the result of this application is an estimate of how strong your password is, thus no guarantee is given on the use of your password.

• If your password is short (less than 8 characters) or your password is common among known passwords, then a Warning message will be given.
• The password strength is determined by the table below:
  

  Length (bits)	Strength
  < 28	Very Weak
  28 - 35	Weak
  36 - 59	Reasonable
  60 - 127	Strong
  > 128	Very Strong

• Entropy: the number of bits listed for entropy is an estimate based on letter pair combinations in the English language. To make the frequency tables a reasonable size, all non-alphabetic characters are merged together into the same group. Because of this, your entropy score will be lower than your real score when you use several symbols.
• For determining the character set, letters are grouped into a-z, A-Z, numbers, symbols above numbers, other symbols, and other characters. If your passphrase contains a character from the subset, that subset is added to the pool, increasing the size of the character set and increasing the amount of entropy in your password.
