----------------------------------------
Summary: Configure hash algorithm in wrapped encryption keys
Key: HBASE-25181
URL: https://issues.apache.org/jira/browse/HBASE-25181
Project: HBase
Issue Type: Improvement
Affects Versions: 2.3.2
Reporter: Mate Szalay-Beko
Assignee: Mate Szalay-Beko
Currently we are using MD5 hash algorithm to store a hash for encryption keys.
This hash is needed to verify the secret key of the subject. (e.g. making sure
that the same secrey key is used during encrypted HFile read and write). The
MD5 algorithm is considered weak, and can not be used in some (e.g. FIPS
compliant) clusters.
In the patch I plan to:
* introduce a backward compatible way of specifying the hash algorithm. This
enable us to use newer and more secure hash algorithms like SHA-384 or SHA-512
(which are FIPS compliant).
* change the algoritm used by the hbase shell to generate secure keys for
column family encryption (this is only used for testing schema in the shell,
the proper data keys are generated by the Java API, see e.g. HBASE-10951)
