revdgst

revdgst is a collection of tools designed for analyzing and reverse engineering checksums specifically in short data packets, with a focus on software-defined radio (SDR) data transmission from sensor modules. Key features include the ability to reverse various checksum algorithms, such as 8-bit and 16-bit LFSR digests and simple checksum methods, while supporting multiple operating systems like Linux, MacOS, and Windows. The tools are implemented in portable C and require input files containing hexadecimal messages to perform analysis.
