Utility to calculate BLAKE-224, -256, -384, -512 checksums.
From source, if you have Go installed:
$ go get github.com/dchest/blakesum
blakesum [-a=224|256|384|512] [filename1] [filename2] ...
By default calculates BLAKE-256 sum. Pass option "-a=xxx" before filenames to calculate BLAKE-xxx, where xxx is 224, 256, 384, or 512. If no filenames specified, reads from stdin.
$ echo -n "Hello world" | blakesum
