You can give meaning to things in some format that don't have meaning in their intended format. Which is rendered as This is a short textĬontains 4 bits of hidden data. For example: 2 spaces -> 1 bit, 3 spaces -> 0 bit so this text in html: This is a short text. But these spacings you can use to encode bits. You can hide text in html by abusing the fact that multiple spaces are rendered as a single space so when you open the file in a browser you see nothing. Encode each line separately (useful for when you have multiple entries). outguess To encode binaries (like images, documents, etc.) use the file upload form a little further down on this page.
