Hi, 
is there any way to encrypt the user id details/password/secrets/connect uri string which are passed in kafka/confluent connect configuration while creating the connector.

for example below, wanted to encrypt mongodb.user and mongodb.password
{
"name": "mngdbz-0316",
        "config":{
            "connector.class": "io.debezium.connector.mongodb.MongoDbConnector",
"mongodb.hosts": "srver host",
"mongodb.name": "DB",
"mongodb.user": "user name",
"mongodb.password": "password",
"mongodb.authsource": "$external",
"mongodb.ssl.enabled": true
        }
}

for ex:
"connection.uri": "mongodb://username:password@sever:27017/?ssl=true&readPreference=secondaryPreferred&serverSelectionTimeoutMS=60000&connectTimeoutMS=60000&replicaSet=RSDEV01&authSource=$external&authMechanism=PLAIN",

the problem if we dont do encrypt, if someone download the connector configuration, they can see user/passed details.

Robin Moffatt has a great write up on how to do this.

That was a very good write-up. 
You can load config from anywhere if you can write an implementation for org.apache.kafka.common.config.provider.ConfigProvider.
If you got a secret store like HashiCorp Vault, you can load the credentials directly from secret store. An example can be found at https://gitlab.com/axual-public/vault-config-provider/-/tree/master
