Testing the validity of a downloaded file

To test that a file is unmodified, ensure that the downloaded file’s checksum matches with the checksum published by AGI. The checksums for current AGI software downloads can be found at the bottom of this page.

To find the SHA-256 checksum:

You should check against the SHA-256 checksum because that is the algorithm used by AGI to generate these values. There are built in tools for all operating systems:

• For Windows, you can use PowerShell Get-FileHash.
• For Linux, you can use sha256sum -c.
• For Mac OSX, you can use the md5 or shasum commands.
