This section provides detailed information on how to integrate the Netcetera 3DS SDK.
Steps to include the SDK into the project:
1 2 3 4 5 6 7 8 9 | target 'test-project' do # Comment the next line if you're not using Swift use_frameworks! pod 'ThreeDS_SDK', '2.3.20'end |
Note: Cocoapods will automatically strip the unsupported architectures (simulator) when archiving the app.
Note: For example <hostname> can be merchant-plug-in.extranet.netcetera.biz.
1 2 3 | machine <hostname>login <myUsername>password <myPassword> |
Extract the Netcetera iOS 3DS SDK zip archive that is part of the delivery. Inside there is one framework ThreeDS_SDK.framework
In your project, add the framework in the “Frameworks, Libraries, and Embedded Content” section in the General target’s tab.
Create a new “Run Script Phase” in your app’s target’s “Build Phases” and paste the following snippet in the script text field:
1 | bash "${BUILT_PRODUCTS_DIR}/${FRAMEWORKS_FOLDER_PATH}/ThreeDS_SDK.framework/strip-frameworks.sh" |
Note: This step is required when archiving universal binaries, otherwise there will be an error [ERROR ITMS-900087: “Unsupported Architecture.”] when uploading the app to App Store.
A license file containing a license key is distributed along with the SDK. In order to be able to use the Netcetera iOS 3DS SDK, the license key must be added in ConfigParameters which are passed upon Initialization of the ThreeDS2Service.
To define the license, use the ConfigParameters.addParameters(...) with the following arguments:
| Argument | Value |
|---|---|
| group | nil |
| paramName | "license-key" |
| paramValue | The content of the license file. |
1 2 | let configParameters = ConfigParameters()try configParameters.addParam(group:nil, paramName:"license-key", paramValue:"eyJhbGciOiJ...") |
An easier way to pass the license key is to use the ConfigurationBuilder. This is done by using the license(key: String) function. The builder helps populate ConfigParameters easier.
After setting all values in the builder, simply call .configParameters() to generate the ConfigParameters object that can be passed in the initialize method of ThreeDS2Service class.
1 2 3 4 5 | let configurationBuilder = ConfigurationBuilder()try configurationBuilder.license(key: "sample_key")let configParameters = configurationBuilder.configParameters() |
Several external dependencies are used by the Netcetera iOS 3DS SDK. These libraries are integrated inside the SDK. The full list of dependencies is:
| Name | Description | Website | License | Version |
|---|---|---|---|---|
| ASN1Decoder | Used to parse keys and certificates in ASN1 structure | https://github.com/filom/ASN1Decoder | MIT license | 1.2 |
| SwCrypt | Library with crpto functions used in the SDK for JWS validation and signing, used only in iOS 10 | https://github.com/soyersoyer/SwCrypt | MIT license | 5.1.3 |
| GMEllipticCurveCrypto | Security framework used for Elipctic Curve keys | https://github.com/ricmoo/GMEllipticCurveCryptо | BSD 2-Clause “Simplified” License | 1.1 |
EMVCo 3DS Specification requires the communication between the 3DS SDK and the ACS to go through HTTPS, but there is no such requirement for what protocol to be used when downloading the Payment System and Issuer logo images that shall be shown in the challenge screens. The URLs of these images are provided as parameters by the ACS in the CRes and it is expected they will be HTTPS URLs. The SDK doesn’t have influence over this and if HTTP URLs are provided, the images will not be shown on the challenge screens.
More information about this and how to ensure that these images will be downloaded and shown on the challenge screen even if they are served using unsecured connection, please check Preventing Insecure Network Connections
