> Common secure credential protection mechanism in Flink SQL
> ----------------------------------------------------------
>
> Key: FLINK-28028
> URL: https://issues.apache.org/jira/browse/FLINK-28028
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API, Table SQL / Runtime
> Reporter: Jing Ge
> Priority: Major
>
> Currently, the most common way to use credential is to use:
>
> CREATE TABLE mytable (
> ...
> )
> WITH (
> 'connector' = 'kafka',
> 'properties.bootstrap.servers' = '...:9092',
> 'topic' = '...',
> 'properties.ssl.keystore.password' = <password>,
> 'properties.ssl.keystore.location' = ...,
> 'properties.ssl.truststore.password' = <password>,
> 'properties.ssl.truststore.location' = ...,
> );
> The credential could then be read by calling SHOW CREATE TABLE <TableName>.
> We should provide a more strong way to protect the credential.
