SSL

As part of the connection options, you can specify the ssl object property or a string containing the SSL profile content (deprecated).

ssl?: string | SslOptions;

See full list of SslOptions, which are in the same format as tls.createSecureContext.

SSL Options​

To enable SSL without manually providing certificates and assuming they are already trusted by the host machine, you can specify an empty object, for example:

const connection = await mysql.createConnection({
  host: 'localhost',
  ssl: {},
});

You can also specify custom certificate(s) as an individual string or array of strings. Please note the arguments expect a string of the certificate, not a file name to the certificate:

import fs from 'node:fs';

const connection = await mysql.createConnection({
  host: 'localhost',
  ssl: {
    ca: fs.readFileSync(__dirname + '/mysql-ca.crt'),
  },
});

When a certificate is read from an environment variable, it's recommended to replace escaped \n characters with proper new line characters, for example:

const connection = await mysql.createConnection({
  host: 'localhost',
  ssl: {
    ca: process.env.DB_SSL_CA?.replace(/\\n/gm, '\n'),
  },
});

SSL Certificate Bundle​

Alternatively, you can use a bundle with CA certificates. For example for Amazon RDS you could use:

import awsCaBundle from 'aws-ssl-profiles';

const connection = await mysql.createConnection({
  host: 'db.id.ap-southeast-2.rds.amazonaws.com',
  ssl: awsCaBundle,
});

For detailed instructions, please follow aws-ssl-profiles documentation.

SSL Profile (deprecated)​

There is also a deprecated option allowing to specify a string containing name of SSL profile:

const connection = await mysql.createConnection({
  host: 'localhost',
  ssl: 'Amazon RDS',
});

Following profiles are included in the package:

Ignoring Unauthorized SSL Errors​

You can also connect to a MySQL server without providing an appropriate CA to trust. This is highly discouraged as being insecure.

const connection = await mysql.createConnection({
  host: 'localhost',
  ssl: {
    // Beware, set `rejectUnauthorized` as `false` is strongly discouraged for security reasons:
    rejectUnauthorized: false,
  },
});
