我正在运行Android KitKat的平板电脑设备以及Lollipop上的Samsung Tab-A上遇到此问题。在运行Android M的Acer平板电脑上，效果很好。
这是失败点：
private KeysetHandle getOrGenerateNewKeysetHandle() throws IOException, GeneralSecurityException {
return new AndroidKeysetManager.Builder()
.withSharedPref(getApplicationContext(), TINK_KEYSET_NAME, TINK_PREF_FILE_NAME)
.withKeyTemplate(AeadKeyTemplates.AES256_GCM) // Failure point
.withMasterKeyUri(ANDROID_KEYSTORE_TINK_MASTER_KEY_URI)
.build()
.getKeysetHandle();
}
然后在初始化Tink时初始化AEAD：
// google\Tink crypto
try {
TinkConfig.register();
aead = AeadFactory.getPrimitive(getOrGenerateNewKeysetHandle());
Log.i(LOG_TAG, "Tink registered.");
} catch (GeneralSecurityException | IOException e) {
e.printStackTrace();
Log.e(LOG_TAG, "Tink failed to register or could not generate a keyset handle.");
Log.e(LOG_TAG, "Tink failed to register: " + e.getMessage());
}
无论哪种方式，Tink都无法使用以下捕获的消息进行初始化：
10-03 16:10:58.319 com.mycompany.myapp.debug E/MainActivity: Tink failed to register: KeyGenerator AES implementation not found
是否有特定的KeyTemplate可以替换以下内容？
AeadKeyTemplates.AES256_GCM

答案 0 :(得分：0)
当在Tink v1.2.0上遇到问题时，以下作为临时解决方法。对于23以下的Android SDK，我们在构建keysetManager时跳过使用密钥库。
但是，这应该不再是Tink v1.2.1（发行时）的问题，因为我已经测试了最新的HEAD-SNAPSHOT并且没有遇到崩溃。
