Adds a new 'Extract Files' operation which detects files within a blob of data, parses them, and then extracts them.

Currently supports

  • JPG
  • EXE
  • ZIP
  • PDF
  • PNG
  • BMP
  • FLV
  • RTF
  • DOCX, XLSX, PPTX
  • EPUB
  • GZIP
  • ZLIB
  • ELF, BIN, AXF, O, PRX, SO

A Stream class has been added in src/core/lib/ to help parsing binary protocols.

TODO

  • Refactor file type detection to include more powerful search methods. I expect to address Support magic files for filetype detection #369 with this.
  • Refactor 'Scan for embedded files' to run much more efficiently. Pass offset to magic number check rather than reslicing the blob every time.
  • Add 'Move to input' button to displayFilesAsHTML function
  • Update 'Untar' operation to use the Stream lib.
  • ELF file format extractor
