Convert p12 APNS certificate to base64 string

Question

I want to send the .p12 file of APNS certificate to One Signal API, but I need first to convert the .p12 file to base64 string. How do I do that? The API documentation is below: https://documentation.onesignal.com/reference#create-an-app

The script I am building is in Node. – Catgut

The script that I have tried but did not work: new Buffer(fs.readFileSync(__dirname + "/ios_push_certificate.p12", 'binary')).toString('base64') – Catgut

Answer 1

new Buffer(fs.readFileSync(__dirname + "/ios_push_certificate.p12")).toString('base64')

That is the correct script after all.

Answer 2

If you're on a Mac you can use the base64 utility that comes with Mac.

base64 -i certificate.p12 -o outputfile

Is it possible to reverse this process? – Coopersmith

I mean base64 to p12 – Coopersmith

@Coopersmith base64 --decode -i outputfile > certificate.p12 – Tempting

Answer 3

You can use this on Linux

base64 file.p12

To write the base64 output to any file, you can use this

base64 file.p12 > output.base64

Note: This works for any files not only .p12

This depends on the programming language you are using.

For example, here's how to do it in Ruby:

base64_encoded_p12 = Base64.encode64(File.read('/path/to/your/file.p12'))
