Provider elements() method in Java
An enumeration of the values in the hash table can be obtained using the method elements() in the class java.security.Provider. This method requires no parameters and it returns the enumeration of the values in the hash table.
A program that demonstrates this is given as follows −
Example
import java.security.*;
import java.util.*;
public class Demo {
public static void main(String[] argv) {
try {
SecureRandom sRandom = SecureRandom.getInstance("SHA1PRNG");
Provider p = sRandom.getProvider();
Enumeration<Object> enumeration;
enumeration = p.elements();
System.out.println("The Enumeration of the values is:
");
while (enumeration.hasMoreElements()) {
System.out.println(enumeration.nextElement());
}
} catch (NoSuchAlgorithmException e) {
System.out.println("Error!!! NoSuchAlgorithmException");
}
}
}Output
The Enumeration of the values is: SHA1withDSA SHA1withDSA SHA1withDSA Software sun.security.provider.JavaKeyStore$DualFormatJKS SHA sun.security.provider.SHA sun.security.provider.JavaKeyStore$CaseExactJKS Software sun.security.provider.DSA$SHA256withDSA SHA SHA1withDSA Software Software Software sun.security.provider.DSA$RawDSA X.509 java.security.interfaces.DSAPublicKey|java.security.interfaces.DSAPrivateKey sun.security.provider.certpath.IndexedCollectionCertStore sun.security.provider.Sun SHA SHA1withDSA sun.security.provider.DomainKeyStore$DKS Software SHA256withDSA SHA224withDSA 1024 1024 Software sun.security.provider.DSAKeyFactory sun.security.provider.ConfigFile$Spi SHA1withDSA SHA-224 DSA Software SHA-512 SHA-384 SHA-256 NONEwithDSA SUN DSA RFC3280 sun.security.provider.PolicySpiFile 2048 DSA DSA SHA1withDSA DSA sun.security.provider.SHA5$SHA384 sun.security.provider.SHA2$SHA224 Software sun.security.provider.DSAParameterGenerator java.security.interfaces.DSAPublicKey|java.security.interfaces.DSAPrivateKey sun.security.provider.NativePRNG$Blocking sun.security.provider.SHA5$SHA512 DSA sun.security.provider.certpath.SunCertPathBuilder SHA1withDSA SHA-224 Software SHA-512 1.8 SHA-384 2048 SHA-256 sun.security.provider.DSAParameters java.security.interfaces.DSAPublicKey|java.security.interfaces.DSAPrivateKey sun.security.provider.certpath.CollectionCertStore Software sun.security.provider.NativePRNG$NonBlocking 2048 sun.security.provider.certpath.ldap.LDAPCertStore sun.security.provider.X509Factory SHA256withDSA SHA224withDSA sun.security.provider.NativePRNG RFC2587 Software Software RFC3280 Software sun.security.provider.DSA$SHA224withDSA SHA1withDSA sun.security.provider.certpath.PKIXCertPathValidator SHA 2048 sun.security.provider.SecureRandom sun.security.provider.DSA$SHA1withDSA DSA Software sun.security.provider.DSAKeyPairGenerator SUN (DSA key/parameter generation; DSA signing; SHA-1, MD5 digests; SecureRandom; X.509 certificates; JKS & DKS keystores; PKIX CertPathValidator; PKIX CertPathBuilder; LDAP, Collection CertStores, JavaPolicy Policy; JavaLoginConfig Configuration) DSA SHA1withDSA sun.security.provider.MD5 SHA1withDSA sun.security.provider.SHA2$SHA256 DSA java.security.interfaces.DSAPublicKey|java.security.interfaces.DSAPrivateKey sun.security.provider.MD2
