How can encrypt the data base fields when using the hibernate?

We have developed the product some of the clients are using that application Some clients is asking about the data base encryption Is there any possible to encrypt the data in application level with out more changes in the code.

Please give me the suggestion as soon as possible.

Try this:

Put an attribute in your entity:

private byte[]  encryptedBody;

Use this getter and setters:

@Column(columnDefinition= "LONGBLOB", name="encryptedBody") 
@ColumnTransformer(
  read="AES_DECRYPT(encryptedBody, 'yourkey')", 
  write="AES_ENCRYPT(?, 'yourkey')")
public byte[]  getEncryptedBody() {
    return encryptedBody;
}

public void setEncryptedBody(byte[]  encryptedBody) {
    this.encryptedBody = encryptedBody;
}

And then when you retrive the column use:

private final Charset UTF8_CHARSET = Charset.forName("UTF-8");

String decodeUTF8(byte[] bytes) {
    return new String(bytes, UTF8_CHARSET);
}

String s = decodeUTF8(entity.getEncryptedBody());

BEWARE: AES_DECRYPT and AES_ENCRYPT belong to MySQL. If you have a different data base engine find similar functions.

Hope this helps.

How to encrypt and decrypt data with Hibernate, Encrypted columns are a common approach for storing sensitive information in a database. You can map them to an entity with Hibernate's  Fast answers on Teoma.us! Find database encryption. Content updated daily for database encryption.

I think that you are looking for column transformers. You can find how to do it in the Hibernate reference:

I hope that helps!

How to map encrypted database columns with Hibernate, The convertToDatabaseColumn method is called by hibernate before the entity is persisted to the database.

You could use jasypt. It has an Hibernate integration that allows you to encrypt properties while saving (and decrypt while loading).

How to use a JPA Attribute Converter to encrypt your data, For encryption at Hibernate, jasypt uses its password-based encryption capabilities, Encrypting the database password in hibernate.cfg.xml. In this post, I will explain how you can encrypt and decrypt data with Hibernate. PostgreSQL crypto module. Because the StackOverflow question mentions PostgreSQL, we first need to enable the pgcrypto extension. For this purpose, we need to execute the following statement: CREATE EXTENSION pgcrypto;

As explained in this article, you can use the @ColumnTransformer annotation like this:

@ColumnTransformer(
    read =  "pgp_sym_decrypt(" +
            "    storage, " +
            "    current_setting('encrypt.key')" +
            ")",
    write = "pgp_sym_encrypt( " +
            "    ?, " +
            "    current_setting('encrypt.key')" +
            ") "
)
@Column(columnDefinition = "bytea")
private String storage;

This way, Hibernate will be able to encrypt the entity attribute when you persist or merge it and decrypt it when you read the entity.

Jasypt + Hibernate 3.x, The following example uses JPA, Hibernate UserType and Jasypt, a very good library to deal with encryption and hashing. The first step is to add  Encrypted columns are a common approach for storing sensitive information in a database. You can map them to an entity with Hibernate's @ColumnTransformer.

If you need to use Java's cypher, you could use this library. It brings new types field for hibernate mapping.

Encrypting your user's data in the DB (Example), “Always Encrypt” feature which is with SQLServer 2016 and above. method for “nvarchar” data type db columns instead of setNString(), which  Encryption of database password using Jasypt is pretty straightforward. For the newer versions of Hibernate (4.2.x, 4.3.x) the existing jasypt-hibernate4 library will not work, you can use the extension I have developed which is available from Maven Central.

Always Encrypt with Hibernate - Hibernate ORM, As Hibernate has quite a big share in the industry for reading and format within the application but in the database, it's stored encrypted. Most databases provide easy to use functions to apply strong encryption algorithms. Unfortunately, the JPA standard does not offer any options to use these functions, but as long as we adhere to the Spring’s default JPA provider, which is Hibernate, we can use its proprietary features.

Encrypting JPA entity attributes using listeners in Spring – Arnold , And what is most interesting now, it also has nice integration with Hibernate allowing seamless encryption/decryption of data stored in database. The term Cipher is a standard term for an encryption algorithm in the world of cryptography. You can use a Cipher instance to encrypt and decrypt data in Java. Read more about Cipher class in JavaDoc .

Transparently persist and retrieve encrypted data from database , Transparent encryption in JPA or Hibernate fields is definitely better than putting the encryption/decryption code in your POJO but it still imposes a  The convertToDatabaseColumn method is called by hibernate before the entity is persisted to the database. It gets the unencrypted String from the entity and uses the AES algorithm with a PKCS5Padding for encryption.

  • possible duplicate of DataBase encryption in Hibernate
  • Tip for cross DB useage - you could create stored procs (or functions) that handles the encryption and decryption for you, and call those via the @ColumnTransformer annotation. So when you have to port to a other DB, you just need to implement those in the DB itself, and bob is your uncle.
  • IMHO this is not how encryption should work. The basic idea is that having only access to DB you would not be able to decrypt the value. Then what is the point if there is a built-in or stored procedure to achieve that? I mean normally the client should be responsible for encrypting and decrypting data...
  • that's solution works perfectly. but are this information converted remotely and send back encrypted, or the encryption will be on hibernate side?(so local to the java process?)
