Password strength and phishing messages

Computer ScienceDigital Safety & EthicsAges 11–12

Type a password and the program counts the character sets used (lowercase, uppercase, digits, symbols), then computes the number of combinations to try as R to the power L and divides by the guessing speed to get the cracking time. Students immediately see why adding one character, or one more character type, makes the cracking time jump. A second mode lets you click suspicious signals in phishing messages to learn to spot online scams.
