LKBEN11524: Howto check the SHA256 from a file
Symptom
You need to be sure you downloaded the right file and you have a SHA256 on the website. A hash value.
Cause
Can be important for security from time to time
Solution
When you download a file and the website also tells you the SHA 256 it should have, you can check it with certutil. Certutil is installed with any java SDK and widely available.
To check the file "testfile.zip" which is located in the c:\temp directory you can use the following command.
certutil -hashfile c:\temp\testfile.zip SHA256
Your output should look like the following. (the SHA-Value will be different)
The following algorithms are available:
MD2, MD4, MD5, SHA1, SHA256, SHA384 and SHA512
To get the MD5 value for the same file as above, you can use:
certutil -hashfile c:\temp\testfile.zip MD5
To ask for more information about hashfile you use:
certutil -hashfile -?
Have fun.
