This is a pure SHA-256 hashing tool written in R, capable of processing:

• ✅ Single files
• ✅ Complete directories (recursive)
• ✅ ZIP archives (auto-extracted)
• ✅ RAR archives (requires unrar CLI)

• R 4.x
• Packages: digest, jsonlite, tools
• System dependency for .rar: unrar must be installed and in PATH

Install required packages:

install.packages(c("digest", "jsonlite", "tools")) 

Rscript file_hasher.R path/to/file_or_folder_or_archive 

Outputs a JSON map of paths → SHA-256 hash values.
