How To Check and Verify SHA-1

Windows 7

Windows doesn’t have a built-in tool to check hashes, but Microsoft does provide one from their website.
Microsoft File Checksum Integrity Verifier Utility
Once you download and extract the file (there’s no installation), open up a Command Prompt window. Navigate to where the file is, and then use the following command to check:

fciv.exe –sha1 C:\path\to\file.zip

Example:

fciv.exe –sha1 C:/download/raspberrypi-fedora-remix-14-r1.img.gz

The SHA-1 digest is displayed as: SHA1 (full path to the file)= [checksum amount]

SHA1(/Users/myaccount/Documents/1024SecUpd2003-03-03.dmg) =2eb722f340d4e57aa79bb5422b94d556888cbf38 <<--compare this with SHA-1 provided by download site.

Mac OS X

1. Open Terminal (located in /Applications/Utilities).
2. Type the following at the Terminal prompt:

sha1 [full path to file]

Example:

sha1 /Users/myaccount/raspberrypi-fedora-remix-14-r1.img.gz

The SHA-1 digest is displayed as: SHA1 (full path to the file)= [checksum amount]

SHA1(/Users/myaccount/Documents/1024SecUpd2003-03-03.dmg) =2eb722f340d4e57aa79bb5422b94d556888cbf38 <<--compare this with SHA-1 provided by download site.

Alternatively for Windows and Mac user, you can use tiny program called HashTab which does exactly the same with minimal effort from you side.

Linux

1. Open Terminal.
2. Type the following at the Terminal prompt:

sha1 [full path to file]

Example:

sha1 /Users/myaccount/raspberrypi-fedora-remix-14-r1.img.gz

The SHA-1 digest is displayed as: SHA1 (full path to the file)= [checksum amount]

SHA1(/Users/myaccount/Documents/1024SecUpd2003-03-03.dmg) =2eb722f340d4e57aa79bb5422b94d556888cbf38 <<--compare this with SHA-1 provided by download site.
