File signature comparison tool, magic numbers.

filesignature

Tool that allows to search, extract, compare the signature of the files (magic numbers) and return the obtained information.

The purpose of this project is to check that a file is valid, i.e. the extension and the hexadecimal signature correspond.

The "byte offset" refers to the position of a specific byte within a file or in a sequence of bytes. 11 byte offsets -> indicates that the first 11 bytes must be shifted to get the desired byte mark.

Install package

pip install filesignature

Usage

>>> from filesignature import FileSignature
>>>
>>> f = FileSignature()
>>>
>>> bytes_data = b'\xef\xbb\xbfhello'
>>> print(f.check_bytes_type(raw_data=bytes_data, extention='txt'))
('EF BB BF', '0', 'txt')
>>>
>>> print(f.check_file_type('file.pdf'))
{'filename': 'file', 'file_extention': 'pdf', 'mimetype': 'application/pdf', 'file_signature': True}
>>>
>>> print(f.check_file_type('file.pdf', get_bool=True))
True
