bitcrypt
BitCrypt is a free ultra-strong encryption that hides text in bitmaps.
...This later step is called steganography, which means "to hide invisibly".
If you intend to store sensitive information invisibly, you may encrypt it with BitCrypt and keep it in a picture image.
Alternatively, if you intend to pass information to another party, you may encrypt it using BitCrypt and publish it as a part of a website. In this manner, another party can access it without anyone realizing that information is transmitted.
The program hides the complexity of its inner workings and is easy to use. It requires only a few steps to perform the task of storing and retrieving text.
