I've started using AWS Glacier, and noticed that it hashes the files using an algorithm called SHA-256 Tree Hash.
To my surprise, this algorithm is different from SHA-256, so I can't use the tools I'm used to, to compare hashes and verify file integrity.
Do you know a Windows tool, if possible integrated in the context menu, to compute the SHA-256 Tree Hash of a file?
I'd also accept a Linux command-line tool, as a second choice :-)
