# FIFA Connect ID

Public and private certificates generation for later use in Connect Service Bus.

## 1. Introduction

In order to achieve secure communication between source and destination MA, message content is encrypted using certificate. Source Member Association (MA) uses public X.509 certificate of destination MA to encrypt entire data content. Then destination MA, which holds private key, decrypts the message using its own private X.509 certificate.

## 2. How to generate and upload certificates

The Windows console application located in `certificate-upload-console` is used for both generating and uploading certificates. When you run it, firstly it will generate public and private certificate and then upload the public one to the server for other MAs to use.

To generate and upload certificate you must provide client id, secret key and environment. You can pass them as parameters:

- `c`: client id
- `k`: secret key
- `e`: environment (use either environment name or environment code from this list: beta, test, int, hfix, prep, prod)

or enter them later when application will ask for them.

### 2.1 Certificate generation

Certificate generation is based on OpenSSL as SSL/TLS toolkit which is embedded in this console application.

After you run this application, you will be prompted to enter secure password for a private key and export password for `PKCS#12` file. The file defines an archive format which is commonly used to bundle a private key with its X.509 certificate and can be imported later in other software using previously entered export password.

Following files will be created in `openssl_output` folder:

- `public_cert.pem`: file with public certificate - will be automatically uploaded to Connect Service Bus so senders can use it to encrypt messages
- `private_key.pem`: file containing created private key - should be kept confidential; you will use it to decrypt messages
- `certificate.pfx`: password protected `PKCS #12` file containing created private key and public certificate - should be kept confidential

To encrypt a message, only `public_cert.pem` file will be used and it will be stored in central Connect Service Bus infrastructure. `certificate.pfx` file will be used locally by MA to decrypt received messages and it should be kept confidential together with `private_key.pem`.

### 2.2 Certificate uploading

Upon generating certificates the application will proceed to upload public certificate. If console application can't be used, certificate can be uploaded using Connect Service Bus SDK. To see how, please refer to FIFA Connect Service Bus SDK documentation.
