What is the best method for getting a SHA2 checksum in windows? I'm looking for something equivalent to md5sums-1.2 utility referenced for putty downloads, with more options than just md5. Edit - after more searching it seems only sha1 sha256 sha512 have working programs for anything outside of hashing text. I want to find the sha2 checksum of a file, is this no dice yet due to sha2 recently becoming popular?

You can install 7-zip 15.14 or later - one of the new features (optionally) adds a hash option to the Windows Explorer context menu, one of which is SHA256 values.
You can use Jacksum, a Java program that has a wide variety of hashes for files and even entire directories.
You might be able to use Gnuwin32 which I believe includes sha1sum and sha256sum.
If you're validating downloads to check for corruption, the Firefox DownloadThemAll addon will actually check the hash as part of the download process!
