Creates signature based on the information needed as per ipay88

# File lib/sha1_encryptor.rb, line 5
def self.request_signature(params)
  # Ref No. is same as order number
  # amount should be stripped of commas and periods. And it should be only till 2 decimal digits
  cipher = params[:merchant_key]+params[:merchant_code]+
  params[:ref_no]+params[:simplified_amount]+params[:currency]
  self.digest(cipher)
end
response_signature(params) click to toggle source

The intended purpose of this method is to verify the signature received from ipay88 for additional security

# File lib/sha1_encryptor.rb, line 14
def self.response_signature(params)
  # payment id is the one received from ipay88. It is different from spree's payment id
  # status  is basically 1 or 0 1= success, 0 = failure. This too, is received from ipay88
  cipher = params[:merchant_key]+params[:merchant_code]+
  params[:payment_id]+params[:ref_no]+params[:simplified_amount]+params[:currency]+params[:status]
  self.digest(cipher)
