Kotlin
Generate JWTs
JWTs are used to authenticate users. Execute the following commands in the terminal to generate JWTs for the users Alice and Bob.
Generate a JWT for Alice
In the following command replace the APPLICATION_ID with the ID of your application:
nexmo jwt:generate sub=Alice exp=$(($(date +%s)+86400)) acl='{"paths":{"/*/users/**":{},"/*/conversations/**":{},"/*/sessions/**":{},"/*/devices/**":{},"/*/image/**":{},"/*/media/**":{},"/*/applications/**":{},"/*/push/**":{},"/*/knocking/**":{},"/*/legs/**":{}}}'
Make a note of the JWT you generated for Alice.
Generate a JWT for Bob
In the following command replace the APPLICATION_ID with the ID of your application:
nexmo jwt:generate sub=Bob exp=$(($(date +%s)+86400)) acl='{"paths":{"/*/users/**":{},"/*/conversations/**":{},"/*/sessions/**":{},"/*/devices/**":{},"/*/image/**":{},"/*/media/**":{},"/*/applications/**":{},"/*/push/**":{},"/*/knocking/**":{},"/*/legs/**":{}}}'
Make a note of the JWT you generated for Bob.
NOTE The nexmo jwt:generate commands shown above set the expiry of the JWT to one day from now, which is the maximum.
NOTE: In a production environment, your application should expose an endpoint that generates a JWT for each client request.
