psst...c'mere. lemme tell you a secret...

Ever needed to create an encrypted string in your Rails app, and decrypt it in your Lucky app? Yeah, me too. There's lots of solutions for encrypting strings, but they all focus on being within the same app.

Thankfully, both Ruby and Crystal support OpenSSL, but it's a bit confusing to use and figure out. All this library does is use the native OpenSSL with minimal setup so you don't have to go digging around docs in several different places.

Installation

Crystal

Add to your shards.yml

dependencies:
  psst:
    github: jwoertink/psst
    branch: master

In your Crystal

require "psst/crystal/src/psst"

Psst.config do |c|
  # must be 8 bytes
  c.salt = "12345678"
  # must be 16 bytes
  c.iv = "1234567890abcdef"
  c.password = "shhsecret"
end

token = Psst.new.encrypt("secret message")
puts Psst.new.decrypt("iREBySRcG8bc80YZoOpB3Q==")

Ruby

Add to your Gemfile

gem 'psst', git: 'https://github.com/jwoertink/psst.git'

In your Ruby

Psst.config do |c|
  # must be 8 bytes
  c.salt = "12345678"
  # must be 16 bytes
  c.iv = "1234567890abcdef"
  c.password = "shhsecret"
end

token = Psst.new.encrypt("secret message")
puts Psst.new.decrypt("iREBySRcG8bc80YZoOpB3Q==")
