Using HashCalc tool to check file integrity

Using hashcalc tool to check file integrity

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.
