SHA Calculator

Jan 1, 2018

SHA Calculator is an online tool to compute the SHA-1, SHA-2, SHA-3 checksum of a string or file locally on your browser. This hash can be used to verify the integrity of the data during transmission. You can provide the expected hash and compare the calculated SHA checksum with it. The SHA hash can be generated in Base64 or Hex formats. The input can be provided in Plain Text, Base64 or as a binary file which you can select from your machine. Hit the Calculate button to generate and check the SHA value

Your file or data will NOT be uploaded. All processing takes place locally inside your browser.

Input: Paste text below


SHA checksum in Hex
SHA checksum in Base64
Hash Matched:
Whether the calculated hash matched with the checksum you provided

SHA-2 is a widely used algorithm to verify the integrity of data during transmission. It is used for verifying the integrity of files downloaded over the internet by comparing the SHA-2 hash of the downloaded file (via computing it) with the one listed on the website.
