可以使用getProvider()
类java.security.Signature中的方法获得签名对象的提供程序。
现在让我们看一个例子-
import java.security.*; import java.util.*; public class Main { public static void main(String[] argv) { try { Signature signature = Signature.getInstance("SHA256withRSA"); Provider provider = signature.getProvider(); System.out.println("The Provider is: " + provider); } catch (NoSuchAlgorithmException e) { System.out.println("Error!!! NoSuchAlgorithmException"); } } }
输出结果
The Provider is: SunRsaSign version 11
现在让我们来看另一个示例-
import java.security.*; import java.util.*; public class Main { public static void main(String[] argv) { try { Signature signature = Signature.getInstance("SHA1withDSA"); Provider provider = signature.getProvider(); System.out.println("The Provider is: " + provider); } catch (NoSuchAlgorithmException e) { System.out.println("Error!!! NoSuchAlgorithmException"); } } }
输出结果
The Provider is: SUN version 11
