How to enable URL signature/sealing for my token?

Applicable Plans: Cloudimage PRO, ROCKET, and ENTERPRISE customers, as well as all Filerobot customers, may use the URL signature/sealing functionalities. These features are meant to prevent your image URLs from being altered (e.g., restricting access to the Original URL, removing the watermark, etc.).

Key Differences:

• URL Sealing: Allows additional parameters to be appended to the image URL (seals only what's encoded in theci_eqs parameter).
• URL Signature: This does not allow additional parameters to be appended.

Important Note: You cannot simultaneously enable URL sealing and URL signature for a single token.

Once activated, these features apply globally, meaning any new or existing image URLs processed with your token will immediately benefit from them.

Steps to Enable URL Sealing or Signature:

1. Choose a SALT Value: Define a secure SALT value that will be used to generate the signature or sealing.

2. Prepare Your Image URLs: Follow the specific guidelines for preparing URLs for:

   • URL Sealing
   • URL Signature
     
     

Common Issues:

If you encounter issues, it might be due to an incorrect passing of the URL query string.

Example:

• When calculating the signature value, if you pass the URL string as http://sample.li/birds.jpg but attempt to load:

  It will not work.
  https://token.cloudimg.io/sample.li/birds.jpg?ci_sign=signature_value


• You should instead load:
  https://token.cloudimg.io/http://sample.li/birds.jpg?ci_sign=signature_value
