Question

我可以通过传递用户名和密码来使用Apache Shiro对用户进行身份验证。但是，如果我已经传递了加密数据，那么我将如何实现呢？我尝试了以下方法：

 public static void main(String[] args) {

    Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
    SecurityManager securityManager = factory.getInstance();

    SecurityUtils.setSecurityManager(securityManager);

    JcaCipherService jcaCipherService =new DefaultBlockCipherService("RSA") ;
    jcaCipherService.decrypt("UOK4yfsmoavRDq+5NiYuMh2s2KC9GBzUCra4MGIx+7ERbdb0IRGsQZxDza7kir/OAupq18Vzm8cZzaHoKeC/TA==".getBytes(), "MIIBVwIBADANBgkqhk".getBytes());

但这是否给我以下错误：

Exception in thread "main" org.apache.shiro.crypto.CryptoException: Unable to acquire a Java JCA Cipher instance using javax.crypto.Cipher.getInstance( "RSA/CBC/PKCS5Padding" ). RSA under this configuration is required for the org.apache.shiro.crypto.DefaultBlockCipherService instance to function.
