What is Encryption?

Answer 1

In cryptography, encryption is the process of obscuring information to make it unreadable without special knowledge.

Answer 2

Putting something in code. For example: coding an e-mail so nobody can read it without a 'key'. Encryptation can be simple (a letter replacement code, for example: abc = zyx and so on. It can be a book code, where two people have the same book and send messages by quoting words from the book according to page, column, paragraph and word. It can also be a software code, usually a mathematical formula, like an advanced version of letter replacement, but massively complex. This usually requires that the receiver receive a 'key', the formula that tells the encryptation software how to decrypt the message.

Answer 3

It's a process of encrypting any messages etc. that you may send via e mail for example. Most people tend not to use it either because they're not sure how to or they can't be bothered. Most businesses will use it for obvious security messages.

What it actually does is scramble your messages so no one else can intercept them and read them except the person you want to.

My son is doing a Phd re. encryption at the moment and he is looking into how much it is used and if not why not with a view to perhaps simplifying how it is used....so that's how I know!

Answer 4

Writing in code so a hacker would not be able to read it by intercepting a copy of whatever encrypted off a 'Net using a sniffer program.

Similar in idea to what generals in battle field tried to do against enemy spy. The best example was what Nazi did using their Enigma machine; I read somewhere a British military branch is still trying to decrypt a message for historical purpose.

Answer 5

encryption is scrambling data. So unauthorised person wouldn't know the contain of the data.
