Field Level Encryption with Spring Boot

colin_sch · February 20, 2025, 10:22pm

I have followed the documentation and I cannot get FLE to work in my SpringBoot Java application…

Whenever I attempt to use an @Encrypted annotation, it responds with the following Exception:

Request processing failed: java.lang.IllegalArgumentException: cryptoManager needed to encrypt/decrypt but it is null. Override needed for cryptoManager() method of org.springframework.data.couchbase.core.convert.AbstractCouchbaseConverter

Code is shown below:

@Configuration
@EnableCouchbaseRepositories("my.repo.under.here")
public class EncryptionConfig extends AbstractCouchbaseConfiguration {

        // Usual Setup
        @Override public String getConnectionString() { return "localhost"; }
        @Override public String getUserName() { return "Administrator"; }
        @Override public String getPassword() { return "admin123"; }
        @Override public String getBucketName() { return "my_bucket"; }

        /* provide a cryptoManager */
        @Override
        protected CryptoManager cryptoManager() {
            try {
                // Load the Java KeyStore
                KeyStore keyStore = KeyStore.getInstance("JCEKS");
                FileInputStream keyStoreStream = new FileInputStream("/Users/asd1983/my-keystore.jceks");
                keyStore.load(keyStoreStream, "test123".toCharArray());

                // Initialize the Keyring with the KeyStore
                Keyring keyring = new KeyStoreKeyring(keyStore, alias -> "keypassword");

                // AES-256 authenticated with HMAC SHA-512. Requires a 64-byte key.
                AeadAes256CbcHmacSha512Provider provider = AeadAes256CbcHmacSha512Provider.builder().keyring(keyring).build();

                CryptoManager cryptoManager = DefaultCryptoManager.builder().decrypter(provider.decrypter())
                        .defaultEncrypter(provider.encrypterForKey("my-key")).build();

                return cryptoManager;
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
    }
}

@Document
public class Data {
  @Id
  private String id;
  @Encrypted
  private String password;
}

package my.repo.under.here;

@Repository
public interface DataRepository extends CouchbaseRepository<Data, String> { }

Hi @colin_sch - your definition looks correct. Do you have any other overrides in EncryptionConfig? Do you have a github repo you could share?

Hi @mreiche , I had a bit more of a play and it works well now!

One question, though, I have this kind of structure here:

@Document
public class Data {
  @Id
  private String id;
  private String password;
  @Encrypted
  private Person person;
}

public static class Person {
  private String name;
  private String phone;
}

So when I save this to the DB, it works fine (including the encrypted Person structure up in the DB). Then, when I attempt to read it again, it throws an Exception and says:

java.lang.NullPointerException: Cannot invoke "Object.getClass()" because "value" is null] with root cause

Do I need to do anything special with the definition here, or what?

Thanks for your help!

Can you post the stack trace?
How do you read it? What method?

colin_sch · February 22, 2025, 6:19am

Hi @mreiche , Here is the entire strackTrace (at the bottom).

Before I get to that, I see what may be the potential problem. This is stored as the encrypted value, taken from the Couchbase DB:

"encrypted$person": {
    "alg": "AEAD_AES_256_CBC_HMAC_SHA512",
    "ciphertext": "sNtxPqZoaAmLRdWOXdEksebWzps+O9yzQtSAymnivAVLYBUjAQCLSBHA6I8nnMGYTzqYPPQEG3oM7N6vqsHNC4KjSitj869CAzUbKmuivwe5/0Kjg0ne6xAsLllAxP/y5eIT9AYGQ+wE8BetJe1gjFecCro0DuQdtp1rP6yRW4Y=",
    "kid": "my-key"
  },

Note: there is no "_class" defined for this (!)
