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() 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 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() 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 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;
