sidecar files creation tool recommendation

[rajah]

I'd like to create .sha256 sidecar files but have had no luck trying to find a program that can create them. Does anyone know of a program where I can select a file and generate a .sha256 sidecar file?

[void]

voidhash

voidhash creates a .sfv, .md5, .sha1 and .sha256 file containing a hash and filename for all files in the specified path (recurses subfolders).
.sfv, .md5, .sha1 and .sha256 files are created in each directory using the parent folder name.
Does nothing if the .sfv, .md5, .sha1 and .sha256 file already exists and has a file size. (doesn't overwrite existing hashes)
Does not change the date modified timestamp on folders.
voidhash is designed for static / archive folders.

Thank you! It sounds like just what I was looking for.
