PhpWebChecksum

PhpWebChecksum is a little php project which aims to provide the means to create checksums for whole websites to be able to monitor which files have changed, have been added or were deleted. A brief introduction can be found in my blog post checking websites for intrusions.

Features

  • a single php script containing all the logic can easily uploaded to any site
  • no data is stored on the server, i.e. nothing is written or changed on your website.
  • for each file on your site a SHA1 checksum, the file dates, owner and unix permissions are stored in an xml document
  • the xml checksum list can be downloaded
  • a locally stored (perviously downloaded) checksum list can be compared with the current state of the website

Known Bugs / Limitations

  • The checksum list and the comparison are generated in memory only. While this is also a feature, the maximium memory size php is allowed to use limits the amount of files that can be checked and compared.

The projects homepage will be hosted on techbits.de under /projects/phpwebchecksum which is already available as well. At this point I have to make sure I can use Keith Devens’ PHP XML Library which I included in my php script and figure out how I’ll solve the pass-by-reference issue when switching between PHP4 und PHP5.
