SilentEye

SilentEye is a software tool described as a cross-platform graphical user interface for steganography. It enables users to conceal text messages or binary files inside ordinary media files, typically images or audio, with the aim of reducing conspicuousness of the payload.

The program implements common steganographic techniques, such as least-significant-bit modification, and can add optional encryption to protect the concealed data. Users typically select a cover file (for example, an image or audio file), input the data to hide, and save a stego-file that appears unchanged to casual observers. When needed, the hidden data can be extracted by reopening the stego-file with the appropriate credentials or password.

Supported media commonly includes standard image formats like PNG or BMP and audio formats such as WAV, though exact compatibility can vary by version. The extraction process reverses the embedding to recover the original payload, assuming the correct key or password is provided when encryption is used.

Security considerations and limitations are an important part of using SilentEye. Steganography aims to conceal the existence of hidden data, but it does not guarantee secrecy against informed or capable adversaries. Detecting the presence of hidden data and recovering it can be possible with analysis. Payload capacity is constrained by the cover file size and quality, and the use of encryption trades off processing requirements and potential overhead for added confidentiality.

Development status and availability of SilentEye have varied over time. Public information about current activity, documentation, and platform support is limited, so users should verify compatibility and consult up-to-date sources before use.
