CRC Calculator

Updated: Jan 2, 2018
CHECKSUM   HASHING   CRYPTOGRAPHY   CRC  
CRC Calculator is an online tool to compute the CRC-16 & CRC-32 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 CRC checksum with it. The CRC hash can be generated in Base64, Hex or Integer 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 CRC value

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