java.security.Signature类的getProvider()方法用于返回此签名对象的提供者。
用法:
public final Provider getProvider()
返回值:此方法返回此签名对象的提供者
下面是说明getProvider()方法的示例:
范例1:
// Java program to demonstrate
// getProvider() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
// creating the object of Signature
Signature sr = Signature.getInstance("NONEwithDSA");
// getting the provider
// by using method getProvider()
Provider provider = sr.getProvider();
// printing the provider name
System.out.println("Provider:" + provider);
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown:" + e);
}
}
}
输出:
Provider:SUN version 1.8
范例2:
// Java program to demonstrate
// getProvider() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
// creating the object of Signature
Signature sr = Signature.getInstance("SHA1withDSA");
// getting the provider
// by using method getProvider()
Provider provider = sr.getProvider();
// printing the provider name
System.out.println("Provider:" + provider);
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown:" + e);
}
}
}
输出:
Provider:SUN version 1.8
