Retrieving Server Public Key in mysqldump

The mysqldump command in MySQL is used to create backups of MySQL databases. One useful option is --get-server-public-key, which allows you to retrieve the public key of the MySQL server during the dump process. This can be particularly useful for securely establishing encrypted connections or verifying server authenticity.

Here are several examples demonstrating the usage of --get-server-public-key in mysqldump:

Example 1: Dumping a database while retrieving the server’s public key:
mysqldump --get-server-public-key=1 -u username -p database_name > backup.sql

This command connects to MySQL as username, dumps database_name, and retrieves the server’s public key, saving the dump to backup.sql.

Example 2: Dumping all databases with server public key retrieval:
mysqldump --get-server-public-key=1 -u username -p --all-databases > all_databases_backup.sql

This command dumps all databases accessible to username while retrieving the server’s public key, saving the output to all_databases_backup.sql.

Example 3: Dumping a specific table with server public key retrieval:
mysqldump --get-server-public-key=1 -u username -p database_name table_name > table_backup.sql

Here, table_name from database_name is dumped with the server’s public key included, stored in table_backup.sql.

To verify if the mysqldump command executed correctly with --get-server-public-key, you can examine the content of the generated dump file. Look for comments or headers indicating the inclusion of the server’s public key. For instance, a comment might specify “-- Server public key is included in the dump file“.

Using --get-server-public-key ensures that during the database dump process, you have access to the public key of the MySQL server, facilitating secure communications and ensuring the authenticity of the server.
