AgoraDynamicKey

For join media channel, use generateMediaChannelKey

For recording service, use generateRecordingKey

Here are sample for C++, java, python and nodejs

Compatibility tables of SDK and Dynamic Key for our customers.

Customers that need verify user ID

Dynamic Key Version	UID	SDK Version
DynamicKey4	specify uid of user	1.3.0 and UP
DynamicKey3	specify uid of user	1.2.3 and UP
DynamicKey	NA	NA

Customers that do not need verify user ID

Dynamic Key Version	UID	SDK Version
DynamicKey4	0	All
DynamicKey3	0	All
DynamicKey	All	All

We recommend all our customers to upgrade to DynamicKey4 ASAP.
