Create your hashes online
With this online converter you can upload a file and calculate the CRC-32 checksum to verify your data. You can also enter data manually and convert it to a CRC-32 hash. By using the HMAC field you can increase the security of your data with a shared key.
The CRC-32 cipher is a non-secure hashing method basically to detect accidental changes of data. More information can be found here: A Painless Guide to CRC Error Detection Algorithms. It's basically used on ethernet, compared to the CRC32B online calculator
