# uhash
Perform hashes of files, streams, etc in parallel.
echo 'hello world' | sha256sum -
Becomes
echo 'hello world' | uhash -with sha256 -
## Installing
go install github.com/KarpelesLab/uhash@latest
## Features
* Read from stdin, a file or an url
* A single read is enough for all the algorithms (useful if reading has a cost, for example if reading from a s3 bucket)
* Calculation is performed in parallel using one goroutine per algorithm
* Specify output format with `-format`, for example `-format json` for json output
* Specify hashing algorithm you want to run, or do not specify anything to run all the available algos
