使用Java进行Hazelcast对称加密检查

Question

Can I check how symmetric encryption works in Hazelcast with Java code or with something another tool? I want to see encrypted values comed from Hazelcast if it's possible.

Config:

    SymmetricEncryptionConfig symmetricEncryptionConfig = new SymmetricEncryptionConfig();
    symmetricEncryptionConfig.setEnabled(true);
    symmetricEncryptionConfig.setAlgorithm("Blowfish");
    symmetricEncryptionConfig.setSalt("asdfdsasdfsadfsadf");
    symmetricEncryptionConfig.setPassword("passwasdsadasdord");
    symmetricEncryptionConfig.setIterationCount(28);

    Config config = new Config();
    config.getNetworkConfig().setSymmetricEncryptionConfig(symmetricEncryptionConfig);

    ListConfig listConfig = new ListConfig();
    listConfig.setName("ISP");
    listConfig.setMaxSize(20);
    config.getListConfigs().put("ISP", listConfig);

    config.getManagementCenterConfig().setEnabled(true);
    config.getManagementCenterConfig().setUrl("http://localhost:8080/mancenter");

    HazelcastInstance server = Hazelcast.newHazelcastInstance(config);

Answer 1

Your configuration seems valid.

To try it yourself you can ask for a Hazelcast Enterprise trial license which is valid for 30 days - https://hazelcast.com/hazelcast-enterprise-download/

The symmetric encryption internally works on Hazelcast packets level. The flow is similar to the PacketEncoder . What makes the difference is the byte output is encrypted by a chosen cipher.

Additional notes

• Symmetric encryption is only used in member-to-member communication! The client-to-member is not encrypted;
• Symmetric encryption can't be used together with TLS;
• Using TLS is preferred over the Symmetric encryption in Hazelcast.
