To check the files using the command prompt, download the program sha256sum.exe. If a file does not match, download it again.

If all of the hashes match, you can burn the ISO file to disc. If the tool does only sha1sum or md5sum, then you can use those files (, ) in our ISO directory for the compare. Make sure the hash displayed by the hash tool for each of the downloaded ISO files exactly matches the corresponding hash in the file. Open the file with a text editor, such as Notepad, to display its contents. It is advisable to uncheck any preselected hash options as they will only slow down the hash calculations. In order to do this open the File Properties window (right click -> File Hashes tab -> Settings), then select the SHA256 option. If you are using HashTab, you will need to enable the SHA256 checksum option. The program takes some time to complete, since it must read the entire ISO file. Then select the SHA256 algorithm for calculation, and run the tool. When you run the program, use the file selection tools provided to select your downloaded ISO image files. Here are links to a few of them:įollow the instructions provided to install the program. There are a number of no-cost products available for file validation and hashing that have point and click interfaces. If it matches for CentOS-6.5-x86_64-minimal.iso, your iso download is good. You would compare the hash received, in this case f9d84907d77df62017944cb23cab66305e94ee6ae6c1126415b81cc5e999bdd0, with the value in the file. Where is the specific ISO you downloaded. Go to the directory where you downloaded the ISO in a command prompt and type: If you wish to verify the clear text signature of the signed (.asc) files, see these detailed instructionsĬhecksum information is also listed via https in the Release Notes for each release and in the archived release announcement.
