Meaning of ENCRYPTION in English
This is the coding or scrambling of information in a file so that it can only be decoded and read by someone who has the correct decoding key. Encryption is commonly used in e-mail and other data transferring so that if someone were to intercept the message or data they would not be able to read it. So if you were sending a message over the office network to your co-worker about how much you hate your job, your boss, and the whole dang company, it would be a good idea to encrypt the message first.
