MSB Steganography Decoder

This tool provides a focused method for detecting and decoding data hidden in images using most-significant-bit steganography. It is designed for digital forensics analysts, security researchers, incident responders, and investigators who need a deterministic approach to test whether an image carries concealed payloads and to extract candidate data for validation. By operating on a supplied image and returning structured results, it supports reproducible analyses and evidence documentation.
Conceptually, the tool treats each pixel's top bit as part of a binary stream and assembles those bits in channel order into bytes. It can target all color channels or a subset, depending on user preferences. The decoder reconstructs the binary payload and presents multiple representations (raw binary, hexadecimal, and ASCII where meaningful). It also provides a payload size estimate and a quick bitplane summary to help analysts assess the likelihood of meaningful data. The workflow is designed to be transparent and auditable, with outputs suitable for further forensic processing.
Unique value comes from a precise MSB-centric design, careful handling of common image formats, and export options that integrate with existing workflows. This tool focuses on the domain logic rather than UI, delivering deterministic results and support for automated pipelines. It is intended for environments where repeatable decodings, simple signatures, and clear data formats are essential for validating or refuting claims of hidden data within images.
