密钥库被篡改或密码不正确

如果密钥库被篡改或密码不正确，可能会导致以下错误之一：

1. KeyStoreException: Invalid keystore format
2. KeyStoreException: Key protection algorithm not found
3. KeyStoreException: Cannot recover key
4. KeyStoreException: Failed to load keystore

下面是一些解决方法的代码示例：

1. 重新导入正确的密钥库文件：

try {
    KeyStore keyStore = KeyStore.getInstance("JKS");
    FileInputStream fileInputStream = new FileInputStream("path/to/keystore.jks");
    keyStore.load(fileInputStream, "password".toCharArray());
} catch (KeyStoreException | FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException | NoSuchAlgorithmException | CertificateException e) {
    e.printStackTrace();
}

2. 检查密码是否正确：

try {
    KeyStore keyStore = KeyStore.getInstance("JKS");
    FileInputStream fileInputStream = new FileInputStream("path/to/keystore.jks");
    keyStore.load(fileInputStream, "wrong_password".toCharArray());
} catch (UnrecoverableKeyException e) {
    e.printStackTrace();
} catch (IOException | KeyStoreException | NoSuchAlgorithmException | CertificateException e) {
    e.printStackTrace();
}

3. 检查密钥库的类型和算法是否正确：

try {
    KeyStore keyStore = KeyStore.getInstance("PKCS12");
    FileInputStream fileInputStream = new FileInputStream("path/to/keystore.p12");
    keyStore.load(fileInputStream, "password".toCharArray());
} catch (KeyStoreException | FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException | NoSuchAlgorithmException | CertificateException e) {
    e.printStackTrace();
}

请确保替换示例代码中的文件路径、密码和密钥库类型等信息为实际的值。
