## Overview

This library supports RTB development for Open RTB common price encryption in Golang.

## Installation

```bash

$ go get github.com/benjaminch/pricers

```

## Supported encryption protocols

### Google Private Data

Specs https://developers.google.com/ad-exchange/rtb/response-guide/decrypt-price

#### Examples

##### Creating a new Google Private Data Pricer

```golang

import "github.com/benjaminch/pricers/doubleclick"

var pricer *doubleclick.DoubleClickPricer

var err error

pricer, err = doubleclick.NewDoubleClickPricer(

    "ZS-DraBUUVeht_sMDgn1nnM3My_nq9TrEESbjubDkTU",   // Encryption key

    "vQo9-4KtlcXmPhWaYvc8asqYuiSVMiGUdZ1RLXfrK7U",   // Integrity key

    true,                                            // Keys are base64

    helpers.Utf8,                                    // Keys should be ingested as Utf-8

    1000000,                                         // Price scale Factor Micro

    false,                                           // No debug

)

```

##### Encrypting a clear price

```go

import "github.com/benjaminch/pricers/doubleclick"

var result string

var err error

price := 42 // Clear price

seed := ""

result, err = pricer.Encrypt(seed, price)

if err != nil {

    err = errors.New("Encryption failed. Error : %s", err)

}

```

##### Decrypting an encrypted price

```go

import "github.com/benjaminch/pricers/doubleclick"

var result float64

var err error

encryptedPrice := "WEp8nQAAAAADG-y45xxIC1tMWuTjzmDW6HtroQ"

result, err = pricer.Decrypt(encryptedPrice)

if err != nil {

    err = errors.New("Decryption failed. Error : %s", err)

}

```
