> Prevent DB2HSM migration tool from overwriting existing keys in HSM
> -------------------------------------------------------------------

> Key: RANGER-5776
> URL: https://issues.apache.org/jira/browse/RANGER-5776
> Project: Ranger
> Issue Type: Bug
> Components: Ranger
> Affects Versions: 3.0.0
> Reporter: Chinmay N Hegde
> Assignee: Chinmay N Hegde
> Priority: Major
> Fix For: 3.0.0

> Time Spent: 20m
> Remaining Estimate: 0h

> Currently, when the master key is migrated from the KMS DB to Luna HSM using
> the migration tool ({*}DB2HSMMKUtil{*}), it silently overwrites any existing
> key present in the HSM. This overwrite should never happen, as it could lead
> to loss of data if the HSM already holds the active master key.
> The fix must be added to check the presence of alias in HSM before writing to
> the HSM. If the alias is already present, the write is skipped and a warning
> is logged.
> This brings the behaviour in sync with how *HSM2DBMKUtil* works.
> (Note: This also needs to be fixed on *RangerSafenetKeySecure* side)
