android - Android 模拟器上的密钥库崩溃

Question

当我尝试获取密钥库密钥时，我的应用程序崩溃了。

我第一次使用密钥库时它不会崩溃，它会在一段时间后开始崩溃......当开始崩溃时，密钥库不再停止崩溃......我在Android Emulator（Android 8）和小米米上测试过9 SE（Android 9）...这不会在我的小米上崩溃。

获取密钥的代码：（崩溃keyStore.getKey()）

fun getSecretKey(keyAlias: String): Key? {
    val keyStore = KeyStore.getInstance(AndroidKeyStore)
    keyStore.load(null)
    return if (keyStore.containsAlias(keyAlias)) {
        keyStore.getKey(keyAlias, null)
    } else {
        null
    }
}

创建密钥库代码：

fun createKeystoreKey(keyAlias: String): Boolean {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        val keyStore = KeyStore.getInstance(AndroidKeyStore)
        keyStore.load(null)

        if (keyStore.containsAlias(keyAlias)) {
            return true
        } else {

            val keyGenerator = KeyGenerator.getInstance(KeyProperties.KEY_ALGORITHM_AES, AndroidKeyStore)
            keyGenerator.init(
                KeyGenParameterSpec.Builder(
                    keyAlias,
                    KeyProperties.PURPOSE_ENCRYPT or KeyProperties.PURPOSE_DECRYPT
                )
                    .setBlockModes(KeyProperties.BLOCK_MODE_GCM)
                    .setEncryptionPaddings(KeyProperties.ENCRYPTION_PADDING_NONE)
                    .setRandomizedEncryptionRequired(false)
                    .build()
            )
            keyGenerator.generateKey()
            return true
        }
    } else {
        return false
    }
}

什么是-32？
