Utilisation de Java pour établir une connexion sécurisée à MySQL Amazon RDS (SSL / TLS)

J'essaie de me connecter en toute sécurité à Amazon RDS en utilisant JDK 1.8 et MySQL Connector/J version 5.1.23 et je suis confus au sujet des instructions dans la documentation MySQL Connector/J.

Les instructions indiquent de créer un truststore dans le répertoire courant et d'importer le certificat CA du serveur. Lorsque j'exécute la commande ci-dessous, on me demande un mot de passe et je ne sais pas quoi entrer: 

keytool -import -alias mysqlServerCACert -file file_location.pem -keystore truststore

Les instructions d'Amazon d'autre part soulignent que les certificats sont signés par une autorité de certification. Le certificat SSL inclut le point de terminaison d'instance de base de données comme nom commun (CN). La clé publique est stockée à http://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem.

Bien que je comprenne le concept de SSL/TSL et de clés privées/publiques, je ne sais pas comment implémenter cela?

Lorsque j'exécute la commande SHOW VARIABLES LIKE 'have_ssl';, je reçois "yes" en tant que valeur. Lorsque je suis connecté à la base de données et que j'exécute SHOW SESSION STATUS LIKE 'Ssl_version'; , je ne reçois pas la valeur de retour.

Comment établir une connexion sécurisée de Java à une base de données MySQL?

Mise à Jour: J'utilise ubuntu et j'ai utilisé le keytool pour générer un fichier truststore.jks dans le répertoire JRE /usr/lib/jvm/java/jre/. J'ai également exécuté la commande suivante: GRANT USAGE ON db_name.* To 'username'@'address' REQUIRE SSL;

Le code ci-dessous est la façon dont je me connecte à la base de données:

import com.mysql.jdbc.Connection;

public class mainClass{

    public static void main(String[] args){

        System.setProperty("javax.net.ssl.trustStore", "/usr/lib/jvm/java/jre/truststore.jks");
        System.setProperty("javax.net.ssl.trustStorePassword", "truststore_password");

        final String url = "jdbc:mysql://mysql_rds_enpoint:port/db_name?verifyServerCertificate=true&useSSL=true&requireSSL=true";
        final String username = "username";
        final String password = "password";

        Connection mysqlConnection = null;
        mysqlConnection = (Connection) mysqlMethods.connectToMysql(url, username, password);
    }
}

Le code ci-dessus produit un message Communications link failure et The last packet successfully received from the server was 24 milliseconds ago. The last packet sent successfully to the server was 24 milliseconds ago. Je suis capable de me connecter avec succès lorsque ?verifyServerCertificate=true&useSSL=true&requireSSL=true est supprimé de l'uri et que REQUIRE SSL est supprimé des autorisations utilisateur.

Mise à Jour 2: J'ai ramené le code à l'essentiel et quand j'exécute le code ci-dessous: 

import java.sql.DriverManager;
import java.sql.SQLException;

class testClass{

    public static void main(String[] args){
        System.setProperty("javax.net.ssl.trustStore", "/usr/lib/jvm/java/jre/truststore.jks");
        System.setProperty("javax.net.ssl.trustStorePassword", "truststore_password");

        final String url = "jdbc:mysql://mysql_rds_enpoint:port/db_name?verifyServerCertificate=true&useSSL=true&requireSSL=true";
        final String username = "username";
        final String password = "password";

        try {
            Object connection = DriverManager.getConnection(url, username, password);
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

Je reçois le message d'erreur suivant:

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

The last packet successfully received from the server was 206 milliseconds ago.  The last packet sent successfully to the server was 203 milliseconds ago.

Lorsque vous exécutez la commande ci-dessous et qu'on vous demande le mot de passe, vous devez taper "changeit". C'est le mot de passe par défaut pour le magasin de clés 

keytool -import -alias mysqlServerCACert -file file_location.pem -keystore truststore

Ensuite, assurez-vous que l'utilisateur mysql que vous utilisez est configuré pour exiger SSL comme ci-dessous

GRANT ALL PRIVILEGES ON test.* TO 'root'@'localhost' REQUIRE SSL;

Ensuite, assurez-vous que le bundle rds que vous avez téléchargé à partir de http://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem{[10] } est importé sur les cacerts java par défaut du serveur d'applications qui tente de se connecter à AWS RDS.

Enfin, vous devez ajouter les trois propriétés ci-dessous avec la valeur 'true' à votre URL mysql 

?verifyServerCertificate=true&useSSL=true&requireSSL=true

Par exemple: 

final String url = "jdbc:mysql://mysql_rds_enpoint:port/db_name?verifyServerCertificate=true&useSSL=true&requireSSL=true";

J'espère que cela aide!

Java keytool n'importe qu'un seul certificat à la fois, mais le bundle RDS combined CA contient de nombreux certificats CA. Vous devrez importer chaque certificat du bundle séparément. Lorsque vous essayez d'importer le bundle, il importe seulement un certificat, qui peut ne pas être l'autorité de certification racine que vous devez faire confiance à l'instance RDS.

Sous linux, vous pouvez diviser le pem avec l'outil CSPLIT: 

csplit -b %02d.pem -z rds-combined-ca-bundle.pem /-----BEGIN/ {*}

Ensuite, vous devez importer chaque pem dans votre magasin de clés séparément.

Sur Mac OS X et FreeBSD, la procédure est similaire. Cela décomposera et importera tous les certificats du rds-combined-cabundle.pem. Vous devrez changer le chemin pour OS X, mais sinon c'est identique. 

split -p "-----BEGIN CERTIFICATE-----" rds-combined-ca-bundle.pem individual-

find . -iname 'individual*' -exec keytool -import -file {} -alias {} -storepass changeit -keystore /usr/local/openjdk8/jre/lib/security/cacerts \;
