Question

If passwords are three uppercase and lower case alphabetic characters long, how much time would it take to determine a particular password, assuming that testing an individual password requires 5 seconds?

Answer 1

Answer:

Time taken to determine a password = 195.29 hours

Step-by-step explanation:

Given

Password = combination of uppercase and lowercase with no restriction

Possibly characters = 26 uppercase+ 26 lowercase = 52

Number of ways to generate characters = 52³

Number of ways = 140,608

Time taken = 140,608 * 5 seconds

Time taken = 703,040 seconds

Convert seconds to hour

703040 ÷ 3600 = 195.2888888888888

= 195.29 hours ----------Approximated

So, time take to determine a password is 195.29 hours
