Example 1 with KeysetToJsonResponse

use of com.google.crypto.tink.proto.testing.KeysetToJsonResponse in project tink by google.

the class TestingServicesTest method toFromJson_success.

@Test
public void toFromJson_success() throws Exception {
    byte[] template = KeyTemplateProtoConverter.toByteArray(KeyTemplates.get("AES128_GCM"));
    KeysetGenerateResponse keysetResponse = generateKeyset(keysetStub, template);
    assertThat(keysetResponse.getErr()).isEmpty();
    byte[] keyset = keysetResponse.getKeyset().toByteArray();
    KeysetToJsonResponse toResponse = keysetToJson(keysetStub, keyset);
    assertThat(toResponse.getErr()).isEmpty();
    String jsonKeyset = toResponse.getJsonKeyset();
    KeysetFromJsonResponse fromResponse = keysetFromJson(keysetStub, jsonKeyset);
    assertThat(fromResponse.getErr()).isEmpty();
    byte[] output = fromResponse.getKeyset().toByteArray();
    assertThat(output).isEqualTo(keyset);
}

Example 2 with KeysetToJsonResponse

use of com.google.crypto.tink.proto.testing.KeysetToJsonResponse in project tink by google.

the class KeysetServiceImpl method toJson.

@Override

    KeysetToJsonResponse response;
    try {
        KeysetHandle keysetHandle = CleartextKeysetHandle.read(BinaryKeysetReader.withBytes(request.getKeyset().toByteArray()));
