spring-data-jpa-encryption-example

An example of how to encrypt and decrypt entity fields with JPA converters and Spring Data JPA. See blog post.

Requirements

Java 11

How is encryption enabled

Entity

There is a User entity which have different fields: id, firstName, lastName, email, birthDate and creationDate.

All fields except id are encrypted in database using AES algorithm.

Repository

There is a simple UserRepository which extends Spring Data JpaRepository.

Converters

Encryption is enabled on fields using different JPA converters: StringCryptoConverter, LocalDateCryptoConverter and LocalDateTimeCryptoConverter. This is verified with UserRepositoryTest integration test.

All converters are unit tested.

Encryption key

Encryption key is empty by default (see example.database.encryption.key configuration key in application.yml).

You have to provide an encryption key in configuration or specify it in options when running application.

Run tests

./gradlew check
