java.security.AlgorithmParameters类的getProvider()方法用于返回此算法参数对象的提供者。
用法:
public final Provider getProvider()
返回值:此方法返回此算法参数对象的提供者。
下面是说明getProvider()方法的示例:
示例1:对于算法DSA
// Java program to demonstrate
// getAlgorithm() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
// creating the object of
// AlgorithmParameters
// and getting instance
// using getInstance() method
AlgorithmParameters
sr
= AlgorithmParameters
.getInstance("DSA");
// genrating the Parameters
// using getAlgorithm() method
Provider pro = sr.getProvider();
// printing the string algo
System.out.println("Provider: "
+ pro);
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown: "
+ e);
}
catch (ProviderException e) {
System.out.println("Exception thrown: "
+ e);
}
}
}
输出:
Provider: SUN version 1.8
示例2:对于算法DiffieHellman
// Java program to demonstrate
// getAlgorithm() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
// creating the object of
// AlgorithmParameters
// and getting instance
// using getInstance() method
AlgorithmParameters
sr
= AlgorithmParameters
.getInstance("DiffieHellman");
// genrating the Parameters
// using getAlgorithm() method
Provider pro = sr.getProvider();
// printing the string algo
System.out.println("Provider: "
+ pro);
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown: "
+ e);
}
catch (ProviderException e) {
System.out.println("Exception thrown: "
+ e);
}
}
}
输出:
Provider: SunJCE version 1.8
