ImSter is a tool that lets you hide and view encrypted text inside images securely. Text is password encrypted using 256-bit AES and encoded into the pixels of the image themselves rather than any metadata. It is impossible for anyone to tell by eye that there is hidden content within an image.

CrypTag is an idea, a spec, an API, and a piece of software that makes it easy to build a zero-knowledge system, which means that the server holding user data doesn't know what it is (since it's encrypted).
<BR><BR>
It is meant as a primitive to be used to build more sophisticated systems that would rather not re-implement the pieces necessary to build a zero-knowledge system, but several useful command line applications have been built with it so far, namely cput (for encrypting/saving files), cget (for fetching/decrypting files), and cpass (CryptPass, a password manager).
