Configurable string extraction and processing tool for binary files.
Performs the following filtering techniques:
- Minimum and maximum string length
- Language detection
- Missing-whitespace
- Impossible ngrams
- Levenshtein similarity filtering
Most of the filtering techniques are configurable base on the command line arguments.
To view filtered strings, use the --logs argument to output the results to a directory.

strictstrings [OPTIONS] <infile>
ARGS:
<infile> Input file to process
OPTIONS:
-b, --bytes Print byte representation after strings
-h, --help Print help information
-l, --logs <logdir> Output filtered values to log directory
-m, --min <MIN> Minimum length of strings to process [default: 6]
-M, --max <MAX> Maximum length of strings to process [default: 200]
-o, --out <outfile> Output file write filtered strings
-q, --quiet Silences all output
-s, --similarity <FLOAT> Sets a custom similarity filtering threshold [default: 0.8]
-t, --language <FLOAT> Sets a custom language detection threshold [default: 0.5]
-V, --version Print version information
-W, --wslen <wslen> Maximum length of strings without whitespace [default: 30]
Base usage:
> strictstrings binary.file
Adjusting thresholds:
