Many of us download files over the internet using Download Managers or Torrent Clients .Sometimes files get downloaded incorrectly or get corrupted.MD5sums and SHA checksums help us verify file integrity. Often Linux Distributions ISO files that are available for download provide MD5 and SHA checksums to verify download.

In Linux system you can calculate these checksum using commands

md5sum <filepath>

sha1sum <filepath>

sha256sum <filepath>

sha512sum <filepath>

In Windows there are utilities available to calculate MD5, SHA1, SHA256 and SHA512 checksums.
  1.   HashCheck
This is a Windows explorer shell extension .You can calculate to MD4, MD5, SHA1 and CRC32 checksums just by right click view properties and checksums tab.

        2. Igorware Hasher
Igorware Hasher is portable utility to check SHA1 MD5 and CRC32 check sums. You can integrate it in windows context menu by going to “Options” and clicking “Integrate with Windows Explorer option” .

HashSlash portable utility helps to calculate MD5, SHA1, SHA256, SHA384, SHA512 and CRC32 checksums of files.
