Calculate values of different hash functions for some piece of data at the same time. Rather efficient, as input is read only once and hashes are calculated in parallel, using all available CPU cores.
You'll need Go workspace set up, read here on how to do that.
$ go get github.com/vderyagin/hashesTo update installation just add -u flag.
hashes accepts single filename as an argument. If no arguments
provided, data is read from stdin.
Three output formats are supported: plain, json and xml:
Usage of hashes:
-format="plain": format of output (allowed values: plain, json, xml)Plain output format:
$ hashes somefile
