- Using pip:
pip install dhashpy -U- Install directly from GitHub:
pip install git+https://github.com/akamhy/dhashpy.git>>> from dhashpy import DHash
>>> file = "/home/akamhy/Pictures/map_of_maths.png"
>>> dhash_file = DHash(file)
>>> dhash_file
DHash(hash=0b0110010000000011101010111100110111001101100011111000111100001110, hash_hex=0x6403abcdcd8f8f0e, path=/home/akamhy/Pictures/map_of_maths.png)
>>>
>>> dhash_file.hash # A 64-bit hash, notice the prefix "0b" indicating it's binary. Total string length = 64 + 2 = 66
'0b0110010000000011101010111100110111001101100011111000111100001110'
>>>
>>> len(dhash_file)

>>> dhash_file.bits_in_hash

>>>
>>> dhash_file.hash_hex
