The toString() method of java.security.Provider class is used to return a string with the name and the version number of this provider.
Syntax:
public String toString()
Return Value: This method returns the string with the name and the version number for this provider.
Below are the examples to illustrate the toString() method:
Example 1:
Java
// Java program to demonstrate// toString() methodimport java.security.*;import java.util.*;public class GFG1 { public static void main(String[] argv) throws Exception { try { // creating the object of KeyPairGenerator KeyPairGenerator sr = KeyPairGenerator.getInstance("DSA", "SUN"); // getting the Provider of the KeyPairGenerator sr // by using method getProvider() Provider provider = sr.getProvider(); // getting the name and version of the provider // using toString() method String nv = provider.toString(); // printing the string info System.out.println("Provider : " + nv); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
Provider : SUN version 1.8
Example 2:
Java
// Java program to demonstrate// toString() methodimport java.security.*;import java.util.*;public class GFG1 { public static void main(String[] argv) throws Exception { try { // creating the object of SecureRandom SecureRandom sr = SecureRandom.getInstance("SHA1PRNG"); // getting the Provider of the SecureRandom sr // by using method getProvider() Provider provider = sr.getProvider(); // getting the name and version of the provider // using toString() method String nv = provider.toString(); // printing the string info System.out.println("Provider : " + nv); } catch (NoSuchAlgorithmException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
Provider : SUN version 1.8
