How to use Cipher MySQL to encrypt your connections
To use Cipher MySQL to encrypt your connections, you need to configure both the server side and the client side to enable and support encrypted connections. You also need to choose the best TLS protocols and ciphers for your needs, and monitor and verify the encryption status of your connections.
How to configure the server and the client for encrypted connections
On the server side, you need to set some system variables that specify the certificate and key files that the server uses when permitting clients to establish encrypted connections. These variables are ssl_ca, ssl_cert, ssl_key. You can set them in the my.cnf file or at runtime using SET statements. For example:
[mysqld] ssl_ca=ca.pem ssl_cert=server-cert.pem ssl_key=server-key.pem
You also need to enable the require_secure_transport system variable if you want to require that clients connect using encrypted connections. For example:
[mysqld] require_secure_transport=ON
On the client side, you need to use some options that indicate whether to use encrypted connections, and which certificate and key files to use. These options are --ssl-mode, --ssl-ca, --ssl-cert, --ssl-key. You can specify them on the command line or in an option file. For example:

How to choose the best TLS protocols and ciphers for your needs
Cipher MySQL supports multiple TLS protocols and ciphers, but not all of them are equally secure or compatible. You need to choose the ones that suit your needs best, depending on your MySQL version , and your security and compatibility requirements. Here are some tips to help you choose the best TLS protocols and ciphers for your needs:
- Use the latest TLS protocol version that is supported by both the server and the client. The latest version is TLSv1.3, which offers improved security and performance over previous versions. However, TLSv1.3 requires both the server and the client to be compiled using OpenSSL 1.1.1 or higher. If you are using an older MySQL version or SSL library, you may need to use TLSv1.2 instead. - Use the most secure ciphers that are supported by both the server and the client. The ciphers are ordered by preference, from most secure to least secure, in the ssl_cipher system variable on the server side, and the --ssl-cipher option on the client side. You can specify a custom list of ciphers to override the default order, or exclude some ciphers that you don't want to use. For example, you can use this command to connect to the server using only AES256 ciphers:
mysql --ssl-mode=REQUIRED --ssl-cipher=AES256
- Avoid using deprecated or unsupported TLS protocols or ciphers. As of MySQL 8.0.26, the TLSv1 and TLSv1.1 protocols are deprecated, and as of MySQL 8.0.28, they are no longer supported. These protocol versions are old and weak, and should not be used for encrypted connections. Similarly, some ciphers may be deprecated or unsupported by MySQL or by your SSL library, and should be avoided as well.
How to monitor and verify the encryption status of your connections
Once you have configured your server and client for encrypted connections, you may want to monitor and verify the encryption status of your connections, to ensure that they are working as expected. You can use some methods to do this:
- Use the SHOW STATUS statement to display information about the current client session, including the SSL_version and SSL_cipher variables that indicate which TLS protocol and cipher are used for the connection. For example:
mysql> SHOW STATUS LIKE 'Ssl%'; +---------------+-----------------+ Variable_name Value +---------------+-----------------+ Ssl_cipher ECDHE-RSA-AES256-GCM-SHA384 Ssl_version TLSv1.3 +---------------+-----------------+
- Use the Performance Schema tables to display information about all active connections to the server, including the SSL_VERSION and SSL_CIPHER columns that indicate which TLS protocol and cipher are used for each connection. For example:
mysql> SELECT THREAD_ID, PROCESSLIST_USER, PROCESSLIST_HOST, SSL_VERSION, SSL_CIPHER FROM performance_schema.threads WHERE TYPE = 'FOREGROUND'; +-----------+------------------+-----------------+-------------+-------------------------------+ THREAD_ID PROCESSLIST_USER PROCESSLIST_HOST SSL_VERSION SSL_CIPHER +-----------+------------------+-----------------+-------------+-------------------------------+ 11 root localhost TLSv1.3 ECDHE-RSA-AES256-GCM-SHA384 12 root 192.168.0.1 TLSv1.2 ECDHE-RSA-AES128-SHA +-----------+------------------+-----------------+-------------+-------------------------------+
- Use a network analyzer tool such as Wireshark or tcpdump to capture and inspect the network packets that are exchanged between the server and the client, and verify that they are encrypted using the expected TLS protocol and cipher.
Benefits of using Cipher MySQL for encrypted connections
Using Cipher MySQL for encrypted connections has several benefits for your data security and privacy, as well as for your connection performance and reliability.
Enhanced security and privacy of your data
By using Cipher MySQL for encrypted connections, you can protect your data from unauthorized access, interception, or modification by malicious actors who may try to exploit vulnerabilities in your network or application. Encryption ensures that your data is only readable by the intended parties who have the proper credentials and certificates.
Cipher MySQL supports multiple TLS protocols and ciphers that offer different levels of security and compatibility. You can choose the ones that suit your needs best, depending on your MySQL version, SSL library, and security requirements. You can also configure which protocols and ciphers to permit or exclude for encrypted connections, to prevent weak or deprecated ones from being used.
Compliance with data protection regulations and standards
By using Cipher MySQL for encrypted connections, you can also comply with data protection regulations and standards that may apply to your data or industry. For example, if you are handling personal or sensitive data of your customers or users, you may need to comply with the General Data Protection Regulation (GDPR) in the European Union, or the California Consumer Privacy Act (CCPA) in the United States. These regulations require you to implement appropriate technical and organizational measures to ensure the security and privacy of your data, and encryption is one of them .
Similarly, if you are working in a regulated industry such as healthcare, finance, or education, you may need to comply with specific standards that mandate the use of encryption for your data. For example, if you are dealing with health information, you may need to comply with the Health Insurance Portability and Accountability Act (HIPAA) in the United States, or the Health Information Technology for Economic and Clinical Health (HITECH) Act in the United States. These standards require you to protect the confidentiality, integrity, and availability of your data, and encryption is one of the ways to do so .
Improved performance and reliability of your connections
By using Cipher MySQL for encrypted connections, you can also improve the performance and reliability of your connections, as well as reduce the overhead and latency that encryption may introduce. Cipher MySQL offers some features and options that help you optimize your connections for encryption, such as:
- Support for TLSv1.3, which is the latest and fastest TLS protocol version that offers improved security and performance over previous versions. TLSv1.3 reduces the number of round trips required to establish an encrypted connection, and introduces new ciphers that are more efficient and secure. - Support for session resumption, which allows clients to reuse previously negotiated TLS parameters to establish new encrypted connections without performing a full handshake. This reduces the overhead and latency of encryption, and improves the connection speed and responsiveness. - Support for compression, which allows clients and servers to compress the data before encrypting it, and decompress it after decrypting it. This reduces the amount of data that is transmitted over the network, and improves the bandwidth utilization and throughput. Alternatives to Cipher MySQL for encrypted connections
Cipher MySQL is not the only option for encrypting your MySQL connections. There are other MySQL encryption options and features that you can use, as well as third-party encryption tools and services that you can integrate with your MySQL server or client.
Other MySQL encryption options and features
MySQL offers some built-in encryption options and features that you can use to encrypt your connections, such as:
- SSL/TLS support, which allows you to enable encrypted connections using SSL or TLS protocols without using Cipher MySQL. You can use this option if you don't need the advanced features or customization that Cipher MySQL provides, or if you are using a MySQL version or SSL library that is not compatible with Cipher MySQL. - Encryption defaults plugin, which allows you to enable encrypted connections by default for all clients that connect to the server. You can use this plugin if you want to simplify the configuration of encrypted connections, or if you want to enforce encryption for all clients without exception. - Connection attributes plugin, which allows you to collect information about the client's SSL/TLS status and other connection attributes. You can use this plugin if you want to monitor or audit your encrypted connections, or if you want to implement policies or rules based on the connection attributes. Third-party encryption tools and services
There are also some third-party encryption tools and services that you can use to encrypt your MySQL connections, such as:
- VPN (Virtual Private Network), which allows you to create a secure tunnel between your client and server over a public network. You can use a VPN if you want to encrypt not only your MySQL connections, but also any other network traffic between your client and server. - ProxySQL, which is a high-performance proxy server for MySQL that supports SSL/TLS encryption. You can use ProxySQL if you want to encrypt your MySQL connections at the proxy level, without modifying your client or server configuration. - Let's Encrypt, which is a free and automated certificate authority that provides SSL/TLS certificates for websites and applications. You can use Let's Encrypt if you want to obtain SSL/TLS certificates for your MySQL server or client without paying any fees or doing any manual work. Conclusion
