If the Sodium extension is installed, Argon 2ID13 will be chosen as the Magento default hashing algorithm. Otherwise, SHA256 will be used.

The Sodium extension is a PHP extension that provides cryptographic functions. Argon 2ID13 is a password hashing algorithm that is considered to be more secure than SHA256.

If the Sodium extension is installed, Magento will use Argon 2ID13 as the default hashing algorithm for customer passwords. If the Sodium extension is not installed, Magento will use SHA256 as the default hashing algorithm.

Adobe Commerce uses secure hashing algorithms for customer passwords. As of the more recent updates, Adobe Commerce defaults to using the Argon2ID13 hashing algorithm, provided that the Sodium PHP extension is available. Argon2ID is considered a secure and modern hashing algorithm designed to protect against brute-force attacks.

If the Sodium extension is not available, Adobe Commerce falls back to using SHA256, which, while secure, is not as robust as Argon2ID13.

This functionality ensures that customer data is safeguarded with the highest level of security available based on the server configuration.

According to the Magento Stack Exchange answer, form key validation is a security feature that prevents CSRF attacks by checking if the form key in the request matches the one generated by Magento. If the developer does not include the form_key in their custom form, the validation will fail and an error will be shown. Therefore, the developer needs to add the form_key to their requests by using getBlockHtml (‘formkey’) ?> in their template file. Verified References: https://magento.stackexchange.com/questions/95171/magento-2-form-validation

In Adobe Commerce, when handling POST requests from forms on the frontend, form key validation is enabled by default as a security measure to prevent Cross-Site Request Forgery (CSRF) attacks. This validation checks that the form submission is coming from the same origin by including a unique token (form key) in the request. If this form key is missing or incorrect, the request will fail, and an error message may be shown on the frontend.

In this scenario:

Since the developer has used \Magento\Framework\App\Action\HttpPostActionInterface, which is appropriate for handling POST requests, it’s likely that the error they encounter is due to missing form key validation.

The solution is to ensure that the form includes a hidden input field for the form key. Adobe Commerce automatically adds this key in forms if you use the \Magento\Framework\Data\Form\FormKey model to get the form key value.

To implement this:

Ensure the form includes the form key:

<input name="form_key" type="hidden" value="escapeHtml($block->getFormKey()) ?>" />

The form key should also be included in the POST data sent to the controller. If it’s missing, Adobe Commerce will not process the request.

Magento 2.4 Form Key and CSRF Protection

To extend the Magento\Catalog\Model\ImageUploader class and configure it with custom basePath and baseTmpPath without affecting other modules that utilize this class, the best approach is to use a Virtual Type. Virtual types allow you to create a customized version of a class for a specific context without altering the original class or its usage elsewhere.

Option A is correct for the following reasons:

Creating a Virtual Type:By defining a virtual type (Vendor\CustomGallery\GalleryImageUpload) in the di.xml, you create a custom version of the ImageUploader class. This virtual type can have unique configurations for basePath and baseTmpPath, which are specific to the custom gallery module.

Explanation: Virtual types are particularly useful in Magento when you need to use a slightly modified version of an existing class in a specific context. In this case, the virtual type allows you to define custom paths without altering the base ImageUploader class, ensuring that other modules using ImageUploader are unaffected.

References: Magento's developer documentation on dependency injection and virtual types highlights this pattern for customizing class behavior in a contained and non-intrusive manner.

Injecting the Virtual Type into the Admin Controller:The custom virtual type is then injected into the Vendor\CustomGallery\Controller\Adminhtml\Image\Upload controller. This ensures that only this controller uses the modified version with the custom paths, leaving other instances of ImageUploader to function with their default settings.

Explanation: By explicitly injecting the virtual type into the controller, you localize the configuration changes to only the desired functionality. This approach is efficient and maintains module independence, a key principle in Magento development.

Options B and C are incorrect for the following reasons:

Option B directly modifies Magento\Catalog\Model\ImageUploader with the new paths. This change will affect all usages of the ImageUploader class across the site, which contradicts the requirement to avoid impacting other modules.

Option C involves creating a virtual type and then setting it as a preference. However, using a preference would replace all instances of ImageUploader across the entire Magento application, leading to the same issue as Option B.

Adobe Commerce Cloud offers several out-of-the-box features, including built-in Fastly integration for CDN and web application firewall services, as well as continuous deployment capabilities through its cloud infrastructure.

Continuous Deployment:

Adobe Commerce Cloud supports continuous deployment workflows, allowing code to be automatically built, tested, and deployed through its integration with Git and cloud CI/CD pipelines.

Fastly Integration:

Fastly is included as a CDN and caching layer with Adobe Commerce Cloud, offering improved site speed and security through caching and a web application firewall.

Why Options B and D are Correct:

Both of these features are inherent to Adobe Commerce Cloud. Option A (Support ACL) is a part of the Magento Admin Panel but is not a cloud-specific feature, and Option C (Blog platform connector) is not provided out-of-the-box.
