Openstego is an open source steganography tool that enables users to hide private data (such as images, text, audio, etc) within other data (such as images, audio, etc). This allows users to share files or messages securely, as the embedded data is not visible to the naked eye. Openstego uses a variety of algorithms to securely store data, including LSB (Least Significant Bit) insertion, F5 and JSteg. Openstego also provides a range of features, such as encryption, password protection and tamper-proofing. Openstego is available as a free download for desktop users as well as a web application, which can be accessed via any web browser.
The discontinued official website cannot be accessed, but the download is still available on the download sites.
