![]() ![]() Encryption is also the basis for all of the other algorithms used in steganography. This alone is a good way to hide the information in the data. Pure encryption algorithms are the best way to convert data into white noise. One of the once practical and secure encryption algorithms still in use today is the data encryption standard (DES). There are many different encryption functions that do a good job of scrambling information into white noise. The trick is to use some extra processing to add a bit of statistical color to the data before it is introduced. Encrypting a file before applying any of the other approaches is a good beginning, but it doesn't complete the picture. This chapter focuses on the basic encryption techniques and algorithms. This effect might not be a good way to divert attention from a file, but it is still an important tool. Standard encryption functions take information and convert it into total randomness or white noise. Peter Wayner, in Disappearing Cryptography (Third Edition), 2009 Publisher Summary
