Within the framework of this study the suitability of the Rust ecosystem for forensic tool development was evaluated. As case study, the tool Stringsext was developed. Starting from analysing the specific requirements of forensic software in general and those of the present case study, all stages of the software development life-cycle have been executed, up to the first production release. Stringsext is a reimplementation and enhancement of the GNU-strings tool, a widely used program in forensic investigations. Stringsext recognizes Cyrillic, CJKV characters and other scripts in all supported multi-byte-encodings while GNU-strings fails in finding these in UTF-16 and other encodings.
During the case study it has become apparent that the Rust ecosystem provides good support for secure coding principles and unit testing. Furthermore, the benchmarks showed a satisfactory performance of the resulting Stringsext binaries comparable to the original C version.
