Can you example for Cipher getInstance()?

Cipher.getInstance("RSA/ECB/PKCS1Padding") Creates a Cipher object (specifying the algorithm, mode, and padding).

Can JDK 1.4 supports RSA (Assymetric cryptography)algoritm?

RSA. This algorithm is the most popular public key cipher, but it's not supported in JDK 1.4.
You must use a third-party library like BouncyCastle to get this support.

How can you add BouncyCastle Provider to to JCE providers list?

public final class BouncyCastleProvider
extends java.security.Provider
implements org.bouncycastle.jcajce.provider.config.ConfigurableProvider

To add the provider at runtime use:

 import java.security.Security;
 import org.bouncycastle.jce.provider.BouncyCastleProvider;

 Security.addProvider(new BouncyCastleProvider());

The provider can also be configured as part of your environment via static registration by adding an entry to the java.security properties file (found in $JAVA_HOME/jre/lib/security/java.security, where $JAVA_HOME is the location of your JDK/JRE distribution). You'll find detailed instructions in the file but basically it comes down to adding a line:

 
    security.provider.=org.bouncycastle.jce.provider.BouncyCastleProvider

Where is the preference you want the provider at (1 being the most preferred).

Program to display Provider services

package com.suresh.security;

import java.security.Provider;
import java.security.Provider.Service;
import java.security.Security;
import java.util.Iterator;
import java.util.Set;

public class ListSecurityProviders {


    public static void main(String[] args) {
        Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
        Provider[] providers = Security.getProviders();
        for(Provider p:providers){
            System.out.println("Provider Name: "+ p.getName());
            System.out.println("services provided are :");
            Set service = p.getServices();
            Iterator itr = service.iterator();
            while(itr.hasNext()){
                Service s = (Service) itr.next();
                System.out.println(s.getAlgorithm());
            }

            System.out.println("\n\n\n");
        }

    }
}

Output:

what is JCA and JCE?

Java Cryptography Architecture (JCA)

Java Cryptographic Extensions (JCE)

The JCE is essentially a framework under the JCA and extends the JCA by simply exposing
more engines and including an additional provider, the SUNJCE provider, that includes one or
more implementations for each engine

The JCE framework places its classes in a different package, javax.crypto. Some of the
JCE specific aspects are Cipher Class (for performing encryption and decryption operations),
KeyGenerator (for producing secret keys used by ciphers), SecretKeyFactory (that operate
exclusively on SecretKey instances), KeyAgreement, and MAC

The term provider refers to a package or set of packages that implement one or more cryptographic services, such as digital signature algorithms, message digest algorithms, and key conversion services

Explain SHA Algorithm?

The secure hash algorithm (SHA) is the set of hash functions designed by the NSA. There are
three SHA algorithms known as SHA-0, SHA-1, and SHA-2, respectively. SHA-1 is the most
popular hash function among the SHA algorithms and is the most widely adopted in commercial
products. There have been some weaknesses discovered in SHA-1, which prompted the creation
of a much stronger SHA-2, and a SHA-3 is also under development and will be chosen based on
a competition somewhere between 2008 and 2012.

The SHA-0 was published as a specification by NIST in the year 1993. This was superseded
in 1995, by SHA-1, which corrected some of the flaws of SHA-0. SHA-1 and SHA-0 generated a
160-bit hash value (message digest) from a variable-length message or file.
SHA-2 was created to overcome of the weaknesses of SHA-1. This consists of the SHA-224,
SHA-256, SHA-384, and SHA-512 algorithms, where the lengths of the message digests are
expressed in the numbers succeeding the word SHA. The NSA has recommended that the use of
SHA-1 be discontinued because of a known flaw in the algorith

Can you give one example of one way hash function?

MD5 is one of the most popular one-way hash functions in the world. The MD5 generates
a 128-bit hash value. The hash function generates a fixed-length hash value after a cleartext
message or file is passed through an encryption algorithm

What is RSA Encryption Algorithm?

The RSA is the first algorithm in the world that can be used for digital signatures as well as encryption

RSA creates a public key and a private key, called a keypair, using its key generation method, from a function of large prime numbers. Data encrypted with the public key can only be decrypted with its corresponding private key and vice versa

RSA is a very popular algorithm in software implementations and is used in operating systems. RSA is also used for key exchange, where symmetric keys are encrypted with the recipient’s public key and sent to the recipient, who can only decrypt the symmetric key with the corresponding private key.

The recommended key length for RSA is 1024 bits and above. Key lengths of 512 bits are not considered secure for current-day implementations. The Java Cryptographic Extensions provide the capability to generate an RSA keypair and perform operations with the generated keys

what are the web service runtime environments available in IBM WAS Server?

Web services runtime environments

Three runtime environments are available in which Web services can run. Each environment supports different servers and standards.

The following runtime environments are supported for Web service generation:

The IBM WebSphere JAX-WS runtime environment is the strategic Web services runtime supported by IBM. The IBM WebSphere JAX-RPC runtime is a legacy environment which is still supported, however new applications should use JAX-WS whenever possible. The Apache Axis 1.4 runtime is an open source runtime supported by the tools, however it is not recommended for use in a production environment.

IBM WebSphere JAX-RPC: WebSphere Application Server v5.0, v5.1, v6.0, v6.1.
Apache Axis 1.3: Apache Tomcat v4.0,.v4.1,.v5.0, v5.5. WebSphere Application Server v5.0, v5.1, v6.0, v6.1.

The following runtime/server configurations are supported:

IBM WebSphere JAX-WS: WebSphere Application Server v6.1.1.3 or later with the Feature Pack for Web Services installed, or WebSphere Application Server v7.0 or v8.0.
IBM WebSphere JAX-RPC: WebSphere Application Server v6.0, v6.1, v7.0, v8.0.
Apache Axis 1.4: Supported on all servers supporting servlet API 2.3 or higher. This includes but is not limited to: Apache Tomcat v4.x,.v5.x, v6.0. WebSphere Application Server v6.0, v6.1, v7.0.

How DWR sends engin.js & Util.js to clent browser?

1. When We are using DWR framework we include engine.js , Util.js and our application specific js files in JSPs like this

Ex:
<%-- DWR script : added in center tile as these scripts are generated at run time--%>



<%-- DWR script --%>

2. if you look at our WEB-INF folder or WAR file we dont see engine.js or utils.js

3. These files are inside dwr.jar file which we calls DWR frawework. DWRServlet serves these JS files from JAR when request comes from browser

4. when browser requested engins.js , request goes into DWR Servlet

Web.xml

dwr-invoker

/dwr/*

Browser Request:

https://www.mysite.com/MYWEBAPP/dwr/engine.js

5. We can look at src code of DWR Frawework

    public BaseEngineHandler()
    {
        super(DwrConstants.PACKAGE_PATH + "/engine.js", DwrConstants.PACKAGE_PATH + "/copyright.txt");
