That's why I wrote it. Encryption is a means to achieve that privacy. It was invented for that very purpose. But encryption, like most things, can be used for good or evil. And the debate over how to harness this powerful tool rages on as people on both sides see that there are no easy answers. .
Encryption is the process of scrambling a message so that only the intended recipient can read it.
A key is supplied to the recipient so that they can then decipher the message. Keys for encryption algorithms are described in terms of the number of bits. The higher the number of bits - the more difficult that cryptosystem would be to break. Encryption can provide a means of securing information. As teachers, we are often called upon to handle sensitive student information.
