Project description
A python library for identifying files by headers (magic bytes)
based on info from: ‘Wikipedia - List of file signatures’
Still alpha, but code should be easy enough to follow and expand upon.
Example use:
# returns a Match object (list of signatures) that match the file 'f' with open(f_name, "rb") as f: derp = get_from_file(f) # returns Match object (list of signatures) that match the file at this file path herp = get_from_path(f_name) # this can be a string or a bytestring, will raise exception if no matching headers found. Matches(header="%PDF")
file_signatures.compare(header, test_hex_string)
A method that compares a two file headers, the first one directly read from a file, the second is a a string containing space delimited hexidecimal byte codes. its a string becuase ‘nn’ is used to represent a wildcard byte.
header
This is the first x bytes of a file, this can be obtained by opening the file using open(file_name, 'rb') mode.
To obtain only the first few bytes use the following:
with open(file_name, 'rb') as f: header = f.read(32)
test_hex_string
This is the string of space delimited hexidecimal byte codes representing the file signature.
‘nn’ is used to represent a wildcard byte
example:
# for example, "%PDF" test_hex_string = "25 50 44 46" # showing wildcards, %P**DF test_hex_string = "25 50 nn nn 44 46"
get_from_file(f, max_header=32)
Return a Match object of all the matching Signatures for this file
f
‘f’ is the open file object.
Note: you can use textIO to get a file like object from a string
max_header
This is the length in bytes read from the start of the file used as the file header.
get_from_path(path, max_header=32)
Return a Match object of all the matching signatures for this file, using the path rather than a file object now.
path
‘path’ is the path to a file, it is passed into open() so it can be relative if you like.
max_header
This is the length in bytes read from the start of the file used as the file header.
file_signatures.Signature
A class that reimplements a dictionary. These are initialised and returned as part of the Match class when a Byte signature is tested using the file_signatures.compare() function.
file_extension
A suggested file extension for this type of file
description
A brief description of the file type taken from ‘List of file signatures’.
offset
Not implemented yet…
ascii
ASCII interpretation of the file signature eg. ‘%PDF’
hex
The space delimited hexidecimal byte codes representing the file signature.
example:
# for example, "%PDF" test_hex_string = "25 50 44 46"
(see above test_hex_string)
file_signatures.Match
This is a list reimplemented, it is returned by get_from_file and get_from_path defs. It holds a list Signature objects.
file_signatures.NoMatchException
This is a basic exception used when a match cannot be found.
Use try: except: statements in your code if you dont like this.
file_signatures.signatures
a list of dictionary items representing a file signature class. Used to check against and initialise new Signatures.
example:
# example entry from file_signatures.signatures list {'ascii': 'v/1.', 'description': 'OpenEXR image', 'file_extension': 'exr', 'hex': '76 2F 31 01', 'offset': '0'}
