The toString() method of java.security.MessageDigest class is used to provide the object of message digest in string format.
Syntax:
public String toString()
Return Value: This method returns the object of message digest in string format.
Below are the examples to illustrate the toString() method:
Example 1:
// Java program to demonstrate // toString() method import java.security.*; import java.util.*; public class GFG1 { public static void main(String[] argv) { try { // creating object of MessageDigest MessageDigest msd1 = MessageDigest.getInstance( "MD5" ); // getting the string value of msd1 // using toString() method String nv = msd1.toString(); // display the result System.out.println( "MessageDigest : " + nv); } catch (NoSuchAlgorithmException e) { System.out.println( "Exception thrown : " + e); } catch (ProviderException e) { System.out.println( "Exception thrown : " + e); } } } |
MessageDigest : MD5 Message Digest from SUN, <initialized>
Example 2:
// Java program to demonstrate // toString() method import java.security.*; import java.util.*; public class GFG1 { public static void main(String[] argv) { try { // creating object of MessageDigest MessageDigest msd1 = MessageDigest.getInstance( "SHA-256" ); // getting the string value of msd1 // using toString() method String nv = msd1.toString(); // display the result System.out.println( "MessageDigest : " + nv); } catch (NoSuchAlgorithmException e) { System.out.println( "Exception thrown : " + e); } catch (ProviderException e) { System.out.println( "Exception thrown : " + e); } } } |
MessageDigest : SHA-256 Message Digest from SUN, <initialized>
