with Alphanumeric Values)
> [Column Masking - Redact] : Numbers and Alphabets are Masked with Different
> Values for Column having Alphanumeric Values
> ------------------------------------------------------------------------------------------------------------------------

> Key: RANGER-5141
> URL: https://issues.apache.org/jira/browse/RANGER-5141
> Project: Ranger
> Issue Type: Bug
> Components: Ranger
> Affects Versions: 2.4.0
> Reporter: Abhishek Jain
> Priority: Major
> Labels: improvement, masking, security-issue
>
> Ranger partially exposes the columns having alphanumeric sensitive
> values(String DataType) if the column is masked using ranger's column masking
> policy with "redact" option.
> _+*Steps to Reproduce:*+_
> 1) Create Hive table and insert data in it.
> 2) Create Ranger Column Masking Policy on a string type column (with
> alphanumeric values) for <testuser> with redact option.
> 3) Fetch this column using <testuser> user in hive/beeline.
> _*With such behaviour, it becomes easier for the un-authorised users i.e
> <testuser> to guess these sensitive values of this particular column masked
> with "redact" option.*_
