/**

|
Debug key management plugin.
|
|
It's used to debug the encryption code with a fixed keys that change
|
|
only on user request.
|
|
|
|
It does not support different key ids, the only valid key id is 1.
|
|
|
|
THIS IS AN EXAMPLE ONLY! ENCRYPTION KEYS ARE HARD-CODED AND *NOT* SECRET!
|
|
DO NOT USE THIS PLUGIN IN PRODUCTION! EVER!
