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') where Query String = /operation/size/filters/original_image_url
The syntax to process an image is:
Because the Salt is a shared secret between you and Cloudimage, only you will be able to calculate the signature of your images.
