Content Security Policy problems

A Content Security Policy (CSP) is a security standard used to add an additional layer of security for web applications. The CSP allows developers to restrict which resources can be loaded, such as JavaScript, CSS, Images, etc.

For some websites, the CSP can block CookieScript scripts such as inline style tags or cookie banner custom functions.

To solve the CSP issues and load the CookieScript code correctly, you can add the nonce attribute that could “whitelist” inline script and style elements. Use a hash to load the CookieScript code. A hash allows the execution of specific inline scripts or styles without enabling all inline code via less secure directives.

To execute the CookieScript code for the banner styles, you have to create a hash for the "cookiescriptstyles" and add this hash to your CSP. Here are the steps to calculate the hash for the "cookiescriptstyles":

1. Identify the inline styles used by CookieScript:
   

2. Generate a hash for these styles using a tool like sha256.

3. Add the generated hash to your CSP under the style-src directive.

For example:

' ' ' plaintext 
style-src 'self' 'sha256-';
' ' '

This approach ensures that you maintain security while still using inline scripts or styles by adding an unsafe-inline.

Note that if you make any changes to your CookieScript banner settings, you will need to recalculate the hash, as it will change with any modifications.
