password validation test cases

Translation:

• matches a string of six or more characters;
• that contains at least one digit (\d is shorthand for [0-9]);
• at least one uppercase; and
• at least one lowercase character.

input	result of test	reason
abcABC	false	no numbers
abc123	false	no uppercase letters
abAB1	false	too short
abAB12	true	-
Aa123456	true	-

another possibilities

I will start by telling you what makes a password strong.

• It has more than 6 characters. The longer the password is, the harder to crack it using brute force attack.
• It contains both small case and upper case characters. This doubles brute force attack time, because it needs to check both cases.
• It contains also numerical characters. This adds another 10 possibilities for each character in the password and thus increases cracking time.
• It contains special characters. This adds another 20 or more characters to the possibilities.
• It contains more than 12 characters. This increases cracking time even more.

My approach was to give one point for each of the conditions above.

And I give a point for each of the conditions, the voting scale is the following

• Very Weak
• Weak
• Better
• Medium
• Strong
• Strongest
