Differs from the KEYGEN_MACRO by not searching for a secret key in the image.
You provide the description to the macro instead and its not a hash but a simple search for a string.
You can use this for hiding a password in a JPEG image if you don't want to use a new file or you can do it in a single JPEG file.
How to use the macros?
A:
Steganography is used to conceal information within another file (usually another file format), sometimes by utilizing metadata (think, tags, hidden text, text in comments, etc). The general goal is to hide the information in such a way that it's very difficult to detect.
One of the main problems with steganography is how to describe the hidden information. This is usually done by using some sort of macro. For example, the commonly-used "search for text" macro is:
This would look for the text between the characters. This is a simple macro that may work well in most cases but can be easily exposed. So the typical solution is to use a complex macro instead that contains some sort of key or algorithm that hides the information.
From the Wikipedia article:
a complex macro or a substitution algorithm, that uses a key to
encrypt or encrypt and decrypt the inserted information into the
surrounding text and to retrieve it.
Examples of common steganography macros:
Take the above example and expand it to something that hides the
word "secret" with a key "mysecretsweetthang":
This macro is commonly called "stego".
There are many variations of this theme. Here are a few others:
Hash the secret into the string and embed the hash and secret.
Use a "hiding key" to encipher the information into a string of
0's and 1's.
Use a "hiding key" and then apply an algorithm to decrypt the string and the secret.
Strip the text and replace the characters that are not part of the
alphabet with 0's.
Have a string of 0's and 1's and insert the information in the
alphabet that is not used by the 0's and 1's.
See if you can make your image come up in your browser and encrypt it. You can use something like 70238732e0 penlfead
