[JavaScript] How to retrieve the certificate and the private key from the KeyStore.
/*
* The following snippet uses the Forge JavaScript library (https://github.com/digitalbazaar/forge)
* to retrieve the certificate and the private key from the keystore. It receives a Forge's PKCS12
* object instance and returns a simple object containing the retrieved certificate and private key
* (assuming that the keystore contains only one certificate). The certificate is required to be sent
* with the signed request, while the private key is used to sign the request before send it.
* For more information about how to use the Forge JavaScript library, please, refer to the aforementioned URL.
*
* Gists provided for illustrative purposes only. Developers can use these as a support tool
* but the Office of the Revenue Commissioners (Revenue) does not provide any warranty with
* these gists.
