Encryption 3
Encryption 3 :
(ICT) Encryption means to scramble a message in such a way that only the people who are meant to read it can do so. A message sent 'in the clear' looks like: "This is a message anyone can read" and the encrypted message looks like gibberish: fu11^&**$$HHPPHDYhg**&&?--20dkmama@()@88787399(&*&))**OJKK@_D. Encryption works by both people making use of a secret 'key' that only they know (or at least their computers know). The original message is mixed in with the key to create a secret message. This is done by some very crafty mathematics so that it is very very hard for someone to crack the code - very powerful computers working for a long time would be needed to crack a good code
