*). Here again, combining characters and symbols can create
a password that is difficult to remember. Therefore, security administrators often favor using pass phrases.
Pass-Phrase Technique
One of the common techniques used today to create strong passwords that are easy to remember is to use a pass phrase. A phrase is a sentence or a word that is easy to remember. A strong password can be derived by using the first letter of each from the pass phrase. In addition, passwords can be made even stronger by using a combination of upper- and lowercase letters,
numbers, and using substitute techniques to replace a character that looks like a letter; for example, i=1, i=!, s=5, S=5, o=Another good technique is to replace any numbers with the uppercase of that number on the keyboard, for example, 1=!, 2=@,
3=#, and 4=$. Users can create different ideas to develop pass-phrase-based passwords resulting in a cipher text. What follows
are some examples of pass phrases:
I can never remember my password = !cNrmp
Quarter pounder with cheese = .25#erwchz
How many times do I need to change my password? = hmtd!n2cmp?
All people seem to need data processing = Ap$2Ndp!ng
Take a long walk off a short pier = taLw0a5P
Sticks and stones will break my bones! = S&5wBmB!
Skilift = Sk1l1ft or Sk!l!ft
