Identifying Hash Algorithms with hashID

Hash algorithms (hash) have become indispensable in authentication systems for software and websites, as well as in blockchain and its programming. This article shows how to identify what hash algorithm a given hash string is using the Linux software hashID. For example, this might be useful in reverse engineering websites and web applications.

If Python is not yet installed, install Python using chocolatey.

choco list --localonly
choco install python --version=3.6.7

For an overview of what chocolatey is and how to install it, see the following:

Windows 11にchocolateyをインストールする

Install hashid with pip.

~$ pip install hashid

Below, as an example, we’ll pass an actual Skein-1024 hash to see if Skein-1024 can be identified.
