An official website of the United States government.
The .gov means it’s official.
Federal government websites always use a .gov or .mil domain. Before sharing sensitive information online, make sure you’re on a .gov or .mil site by inspecting your browser’s address (or “location”) bar.
This site is also protected by an SSL (Secure Sockets Layer) certificate that’s been signed by the U.S. government. The https:// means all transmitted data is encrypted — in other words, any information or browsing history that you provide is transmitted securely.
SHA-512 is a type of checksum that we use to verify file integrity. If you're sharing a file with us, we will probably ask you for a SHA-512 checksum for your file, which we'll verify against our own copy of the file.
Here are some suggestions for generating the SHA-512 checksum for your file for different operating systems on the command line.
Windows:
certUtil -hashfile pathToFile sha512
Mac:
shasum -a 512 pathToFile
Unix (CentOS):
sha512sum pathToFile
