Hi team, PFB details of the task I plan to achieve.

  1. Read from JDBC table
  2. Encrypt data using Tink library
  3. Write encrypted data to BigQuery Note: I am planning to do this using Apache beam Dataflow (Java)

Steps I have completed:

  1. Created a basic template to read from JDBC and write to BigQuery using Google Provide Template https://github.com/GoogleCloudPlatform/DataflowTemplates/blob/HEAD/src/main/java/com/google/cloud/teleport/templates/JdbcToBigQuery.java
  2. Created Key ring and Keys in Google KMS.
  3. For encrypting data I have created Keyset in Java using following code String masterKeyUri = "gcp-kms://projects/<project>/locations/global/keyRings/my-app-keyring/cryptoKeys/testKey"; KeysetHandle handle = KeysetHandle.generateNew(KmsAeadKeyManager.createKeyTemplate(masterKeyUri)); kekAead = handle.getPrimitive(Aead.class); KeysetHandle handle = KeysetHandle.generateNew(KeyTemplates.get("AES256_GCM")); handle.write(JsonKeysetWriter.withFile(new File("./secure_keys.json")), kekAead);

Issues:

  1. When I read the Key "./secure_keys.json" using following code https://github.com/google/tink/blob/master/docs/JAVA-HOWTO.md#loading-existing-keysets File file = new File("./secure_keys.json"); String uri = "gcp-kms://projects/<project>/locations/global/keyRings/my-app-keyring/cryptoKeys/testKey"; KeysetHandle keysetHandle = KeysetHandle.read(JsonKeysetReader.withFile(file),new GcpKmsClient().getAead(uri)); I get the following error Exception in thread "main" java.lang.NoSuchMethodError: com.google.gson.JsonParser.parseString(Ljava/lang/String;)Lcom/google/gson/JsonElement; at com.google.crypto.tink.JsonKeysetReader.readEncrypted(JsonKeysetReader.java:163) at com.google.crypto.tink.KeysetHandle.read(KeysetHandle.java:116) at org.example.analytics.KmsEncryption.initializeOnce(KmsEncryption.java:45) at org.example.analytics.JdbcToBigQuery.main(JdbcToBigQuery.java:18)

To Reproduce:

  1. Jdk 1.8
  2. Maven compiler source & target - 8
  3. Tink - 1.6.0
  4. Tink GCP Kms - 1.6.0
  5. GCP Kms - 1.40.0

Please let me know if I am doing something wrong.

I tried using this code as well https://developers.google.com/tink/generate-encrypted-keyset. Even after using the same code as mentioned in the official documentation, it gives the same error.

Looks like there were conflicts between dependencies. After updating KMS, beam and tink to latest versions I was able to resolve the issue.
