Google Storage creates Signed Urls using your own program instead of using Google Cloud Libraries


super eye

Google Storage allows the use of custom created signed urls as shown in the following link: V4 signing process with your own program

What is the reason? Would this be faster than requesting a signed URL for every object in Google Storage?

Doug Stevenson

The intent is to provide a way to sign URLs without providing any Cloud Storage client library. Since it's a Rest API, you can call it from any language that can make HTTP requests and perform RSA signatures. You link from this page:

This page describes the algorithm used to implement the V4 signing process so that you can create Cloud Storage RSA key signed URLs in your own workflow using the programming language of your choice .

The example shown is in python, but the text makes it clear:

This example uses the Python programming language, but does not use Cloud Storage Client Libraries :
