libsha1-go

Last version: 0.0.1

Pure sha1 function use nothing else. Exported from golang runtime. And some examples of code.

Requirements

To compile library and examples you will need to install

• c99 capable compiler (for now only gcc >=4.8 supported)
• openssl >=1.0 ( libcrypto )
• golang >=1.6

Prepare system

Instructions for Debian/Ubuntu like systems:

apt install build-essential
apt install libssl-dev
apt install golang-go

Compile

If your version of go not default:

GOROOT=/path/to/golang/installdir GO=go-x.y make lib

Reason

Not found library with only one function, so I tryed by myself.

Result

Slightly faster file reading than sha1sum command. But more memory consuming.
