Softrace is a Golang application designed for storing and querying the NIST National Software Reference Library Reference Data Set (NSRL RDS). The tool utilizes Bolt database technology to provide fast and lightweight hash lookup capabilities. The application supports MD5 and SHA1 hash searches against the NSRL database, which contains reference data for known software files. This functionality enables forensic investigators and security professionals to identify known good files during digital investigations. To use Softrace, users must first download the Modern RDS Minimal archive from the NIST Current RDS Hash Sets page and extract the required files (NSRLFile.txt, NSRLMfg.txt, NSRLOS.txt, NSRLProd.txt) into the specified directory structure. The tool includes Docker support for building the database creation environment. The application's compact design and efficient database structure make it suitable for environments where storage space and query performance are important considerations for hash-based file identification tasks.
