TDE and Database replication between servers

Hi folks,

I am attempting to test replication between two MariaDB servers, one production with TDE enabled and the other a scratch environment (no TDE), connected via an SSH tunnel (connectivity and db access confirmed).

Are databases with data at rest able to replicate to either unencrypted partners, or those using different encryption keys?

show slave status\G gives me

Last_IO_Errno: 1595 Last_SQL_Errno: 1594

Relay log read failure: Could not parse relay log event entry. The possible reasons are: the master's binary log is corrupted (you can check this by running 'mysqlbinlog' on the binary log), the slave's relay log is corrupted (you can check this by running 'mysqlbinlog' on the relay log), a network problem, or a bug in the master's or slave's MySQL code. If you want to check the master's binary log or slave's relay log, you will be able to know their names by issuing 'SHOW SLAVE STATUS' on this slave.

And it has never successfully replicated:

Seconds_Behind_Master: NULL

When I look at the logs: mysqlbinlog /var/log/mysql/mysql-bin.000001 , I get:

/*!50530 SET @@SESSION.PSEUDO_SLAVE_MODE=1*/; /*!40019 SET @@session.max_insert_delayed_threads=0*/; /*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/; DELIMITER /*!*/;
