How to initialize the Keystore
提问by user3083447
This my code used for usage of key store to save an arbitrary text as a key in the keystore how I am getting the "Keystore is not initialized error", how can I initialise the Keystore?
这是我的代码用于使用密钥库将任意文本保存为密钥库中的密钥我如何得到“密钥库未初始化错误”，我如何初始化密钥库？
public void secretKeyGeneration(View view) throws KeyStoreException, NoSuchAlgorithmException, CertificateException, IOException {
KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
byte[] sek = "eru9tyighw34ilty348934i34uiq34q34ri".getBytes();
SecretKey sk = new SecretKeySpec(sek, 0, sek.length, "AES");
char[] password = "keystorepassword".toCharArray();
KeyStore.ProtectionParameter protParam =
new KeyStore.PasswordProtection(password);
KeyStore.SecretKeyEntry skEntry = new KeyStore.SecretKeyEntry(sk);
ks.setEntry("secretKeyAlias", skEntry, protParam);
}

Keystores have tobe initialized and hence you have tocall the Keystore.load(...)method. In your case you can for instance invoke:
密钥库必须进行初始化，因此你必须调用该Keystore.load(...)方法。在您的情况下，您可以例如调用：
KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
ks.load(null, null);
byte[] sek = "eru9tyighw34ilty348934i34uiq34q34ri".getBytes();
