> Change encryption key generation algorithm used in the HBase shell
> ------------------------------------------------------------------
>
> Key: HBASE-25263
> URL: https://issues.apache.org/jira/browse/HBASE-25263
> Project: HBase
> Issue Type: Improvement
> Components: encryption, shell
> Reporter: Mate Szalay-Beko
> Assignee: Mate Szalay-Beko
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.4.0

>
> This PR is a follow-up of HBASE-25181 (#2539), where several issues were
> discussed on the PR:
> 1. Currently we use {{PBKDF2WithHmacSHA1}} key generation algorithm to
> generate a secret key for HFile / WalFile encryption, when the user is
> defining a string encryption key in the hbase shell. This algorithm is not
> secure enough and not allowed in certain environments (e.g. on FIPS compliant
> clusters). We are changing it to {{PBKDF2WithHmacSHA384}}. It will not break
> backward-compatibility, as even the tables created by the shell using the new
> algorithm will be able to load (e.g. during bulkload / replication) the
> HFiles serialized with the key generated by an old algorithm, as the HFiles
> themselves already contain the key necessary for their decryption.
> Smaller issues to be fixed:
> 2. Improve the documentation e.g. with the changes introduced by HBASE-25181
> and also by some points discussed on the Jira ticket of HBASE-25263.
> 3. In {{EncryptionUtil.createEncryptionContext}} the various encryption
> config checks should throw {{IllegalStateExceptions}} instead of
> {{RuntimeExceptions}}.
> 4. Test cases in {{TestEncryptionTest.java}} should be broken down into
> smaller tests.
> 5. {{TestEncryptionDisabled.java}} should use {{ExpectedException}} JUnit
> rule to validate exceptions.
