What is the method of encryption for php composer?

PHP Composer does not provide encryption functionality. Composer is a dependency management tool used for managing and installing dependencies for PHP projects. It determines dependencies by reading the composer.json file in the project, and downloads and installs the necessary packages. Composer itself does not involve any encryption or security features. If you need to encrypt or protect PHP code, you may want to consider using other tools or methods such as using encryption algorithms to encrypt code files, or using encryption/decryption functions to handle sensitive data.
