Sample

This will retrieve a file from Truxton, print the name and hash as stored in the database then calculate a hash on the contents and print that.

import truxton
import hashlib

def main():
  t = truxton.create()
  file = t.getfileid("5ec2a123-74d6-5da7-0653-4e6800000000")
  print(file.hash + " is the hash in the database for " + file.name )
  bytes = file.readall()
  readable_hash = hashlib.md5(bytes).hexdigest()
  print(readable_hash + " is the calculated hash of the contents")

if __name__ == "__main__":
  main()
