What is URL signing in CDN?

Everybody who uses CDN sooner or later realize the need to protect their content. Usually URL signing is used for such kind of tasks. URL signing is the most reliable and popular method, that uses the content publication with a special token, that also includes the Time-to-live (TTL) parameter. Such key may be generated only by those who publish file. This also means that every user that tries to access content can be given a unique URL. Such preferences allow to prevent the free distribution of content.

URL signing helps to achieve the following:

- if the user changes URL, the access to content becomes forbidden;

- if the time to live parameter expires, the access to content is also forbidden.

Such method proved to be very reliable and allows to protect data that is transmitted via CDN thoroughly.
