Security

To prevent URL tampering and protect your token, every Cloudimage URL can be secured with an SHA-1 HMAC signature.

The signature is calculated as follows:
Signature = sha1('Salt' + Query String)
With
Query String = '/operation/size/optional_parameters/original_image_url'

The syntax to process an image is: http(s)://company.cloudimg.io/operation/size/optional_parameters@Signature/
original_image_url

Contact us for enabling the signature and generate the Salt for your company token.
