In the context of the feature "Token Protection" in the VideoManager Pro a authentication code must be generated so that videos with token protection can be played out.
In this section, you will learn how to calculate a HMAC-SHA256 based signature for this purpose.
HMAC is a technique that uses hash functions (SHA256) to authenticate messages and to ensure their integrity. Because HMAC is used in conjunction with a key, the input value of the hash function is not only from the message itself, but also from a secret key. This key is known only to you, thus it is only you, who can calculate the appropriate checksum and determine the authenticity and integrity.
