HSMR
|
||||
===========
|
||||
|
||||
HSMR is a collection of cryptographic commands usually implemented on a HSM (Hardware Security Module). These
|
||||
are implemented for your education or for testing purposes and should not be used to replace an actual HSM.
|
||||
|
||||
Installation
|
||||
-------------
|
||||
|
||||
You install it just like any other Ruby gem:
|
||||
|
||||
gem install hsmr
|
||||
|
||||
Usage
|
||||
---------
|
||||
|
||||
require 'hsmr'
