Encryption Demonstrated

Encryption is a highly effective way of keeping your information private. The gibberish below started off as the text of The Ten Commandments, then rendered indecipherable by an encryption algorithm. Unless you know the secret key. Then it's easy to reverse the process.

To demonstrate how a small change to the input completely changes the encrypted output, I removed one period from the text and generated the cyphertext again using the same secret key.   Notice how very different it is from the one above. This is a key attribute of a good encryption algorithm.
