Purpose

The module ImageHash computes the hash value of an input image.

Usage

The input source must be connected to a proper image seource. The selected hashing and encoding algorithms are used to compute the hash.

Details

The hashes provided by this module are taken from a cryptography library.

The main reason for using those instead of the Checksum module is to have less probability for hash collisions.
