Using HashCalc tool to check file integrity

Posted by in Computer Tips | Last updated on

How to be sure that your downloaded file is intact. The simple way is to verify file integrity using SHA-1 hash or another. You need to compare the checksum of that file to the hash of the original file. In order to do that, you will need a checksum tool. I would like to introduce you a small utility named HashCalc. The strength of this tool is to support multiple types of cryptographic hash such as MD5, MD4, SHA1, SHA256, SHA384, SHA512, RIPEMD160, PANAMA, TIGER, MD2, ADLER32, CRC32… You can get HashCalc tool here.

Using HashCalc to verify the authenticity of a file

Step 1: Open HashCalc tool and select the file you want to verify.

If your file is too big, this may take a while.

Step 2: Compare to the hash of source file.

*Note:* If any discrepancies are found, the file can’t be used because of being corrupted.

        I tried scanning hascal with virus total and it reported the .exe having “malicious.799570”. Can you check if that is a malware, virus or something?
