mysql (5.7) Binlog encryption

Question

I am trying to use Binlog feature of mysql to capture changes and feed them to DWH. (my requirement is not for replication).

By looking at official documentation ( https://dev.mysql.com/doc/refman/8.0/en/replication-binlog-encryption.html ) - "From MySQL 8.0.14, binary log files and relay log files can be encrypted.." Does it mean it's not there for versions 5.x?

I am trying to enable Binlog for mysql 5.x instances, and wanted to make sure of security. can I assume it is impossible to have encrypted bin logs for mysql 5.x? As i went through the 5.7 documentation, it (encryption) is no where mentioned ( https://dev.mysql.com/doc/refman/5.7/en/binary-log.html )

I may try to keep the Binary logs for 2 days probably as I am using Nifi to fetch these logs using CaptureChangeMySQL processor and load them to Data warehouse (DWH).. once the DWH is populated, i dont need the logs anymore.

Please help me with your suggestions or understanding..

Answer 1

The version of mysql 5.7 is also possible, and SSL is recommended. Of course, the encryption of statements like DML/DDL is also related to the binlog_fromat parameter.
