Installation

Add this line to your application's Gemfile:

Usage

Get a signing key

signature = ParamSigner::Signer.sign({
  foo: 'bar',
  asdf: 'qwer'
}, my_secret)

signer = ParamSigner::Signer.new(my_secret)
signature = signer.sign({
  foo: 'bar',
  asdf: 'qwer'
})

Verify a signing key

ParamSigner::Signer.valid?({
  foo: 'bar',
  asdf: 'qwer'
}, my_secret, signature)

Or, you can create an instance to reuse:

signer = ParamSigner::Signer.new(my_secret)
is_valid = signer.valid?({
  foo: 'bar',
  asdf: 'qwer'
}, signature)
