Provider getInfo() method in Java with Examples

The getInfo() method of java.security.Provider class is used to return a human-readable description of the provider and its services. This may return an HTML page, with relevant links. 

Syntax:

public String getInfo()

Return Value: This method returns a description of the provider and its services. 

Below are the examples to illustrate the getInfo() method: 

Example 1:

Java

// Java program to demonstrate
// getInfo() method

import 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 info
            String info = provider.getInfo();

            // printing the string info
            System.out.println("info : " + info);
        }

        catch (NoSuchAlgorithmException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output:

info : 
SUN (DSA key/parameter generation;
    DSA signing; SHA-1, MD5 digests; 
    SecureRandom; X.509 certificates; 
    JKS & DKS keystores; 
    PKIX CertPathValidator; 
    PKIX CertPathBuilder; 
    LDAP, Collection CertStores, JavaPolicy Policy; 
    JavaLoginConfig Configuration)

Example 2:

Java

// Java program to demonstrate
// getInfo() method

import 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 info
            String info = provider.getInfo();

            // printing the string info
            System.out.println("info : " + info);
        }

        catch (NoSuchAlgorithmException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output:

info : 
SUN (DSA key/parameter generation; 
    DSA signing; SHA-1, MD5 digests; 
    SecureRandom; X.509 certificates; 
    JKS & DKS keystores; 
    PKIX CertPathValidator; 
    PKIX CertPathBuilder; 
    LDAP, Collection CertStores, JavaPolicy Policy; 
    JavaLoginConfig Configuration)
