Quantcast Choice offers the option to use subresource integrity to ensure the correct version of the Quantcast Choice code is downloaded and has not been tampered with or maliciously altered.
Note: A subresource integrity should only be used if you are using a fixed version of Quantcast Choice, as the default URL receives regular updates and will result in downtime until the integrity hash is manually updated by the user.
If you are a Choice customer, you have the ability to roll forwards or backwards to different versions of Quantcast Choice within your CMP Portal. This will automatically apply the corresponding Integrity Hash.
Developers can navigate to the code release notes to look up the integrity hash for each version.
