How to Fix SubtleCrypto: digest() undefined Error in Authgear SDK
Guide on how to fix SubtleCrypto: digest() non-HTTPS/Secure context Error in Authgear SDK
The Authgear SDK uses a browser API SubtleCrypto: digest() which requires HTTPS. As a result, if your client application that uses the SDK is on HTTP (non-secure), you may run into the SubtleCrypto: digest() non-HTTPS/secure context error.
To use the SDK, your client application must be on HTTPS or be running in secure contexts. Secure contexts include running your application from localhost or 127.0.0.1.
The following are examples of the error messages you will get SubtleCrypto: digest() non-HTTPS/secure context error in Chrome and Firefox.

If you need to run your application on a local environment or for testing where you can't set up HTTPS, consider running your application in secure contexts, For example, http://localhost or http://127.0.0.1.
To run your application from another domain other than a localhost, set up HTTPS on the domain.
