Ember.js makes use of jQuery for DOM manipulation, event handling, animation, and AJAX requests. By using jQuery as a dependency, Ember.js can take advantage of the robust and widely-used library for these tasks, saving time and effort in implementing these features from scratch.

First, you need to read the private key from a file or a variable using the openssl_pkey_get_private function. Then, you can use the openssl_sign function to sign the data with the private key and generate the signature. Finally, you can verify the signature using the openssl_verify function.
