AWS Pinpoint - How to update APNs channel? How to convert a p12-certificate to String?

Question

I want to update the APNs channel of an AWS pinpoint application. For that I have to create a APNSChannelRequest with the SSL certificate and the certificate password. The type of the both elements must be a string.

How can I convert the .p12-file to a string or how can I export the right key out of the .p12-file? (This step can be done manually and does't have to be done at runtime.)

Here is the (slightly extended) example of the developer guide from AWS SDK for Java:

APNSChannelRequest request = new APNSChannelRequest()
    .withEnabled(enabled);

UpdateApnsChannelRequest updateRequest = new UpdateApnsChannelRequest()
    .withCertificate("here comes the ssl-certificate string")
    .withPrivateKey("pw123")
    .withAPNSChannelRequest(request)
    .withApplicationId("placeholder-for-the-appId");
UpdateApnsChannelResult result = client.updateApnsChannel(updateRequest);

I can't find anything in the documentation.

Thanks for your help.

This will require converting the contents of the p12 file to PEM format. This can be achieved via the command line using openssl as follows:

openssl pkcs12 -in certificate.p12 -nodes -clcerts

This will result in the CERTIFICATE and PRIVATE KEY values to be emitted in base64 format. Supply the string beginning with: "-----BEGIN CERTIFICATE-----" and ending with "-----END CERTIFICATE-----" as the Certificate value in the UpdateApnsChannelRequest. Supply the string beginning with "-----BEGIN PRIVATE KEY-----" and ending with "-----END PRIVATE KEY-----" as the PrivateKey value in the UpdateApnsChannelRequest.
