JDK 1.1 Source Code Directory
JDK 1.1 source code directory contains Java source code for JDK 1.1 core classes:
"C:\fyicenter\jdk-1.1.8\src".
Here is the list of Java classes of the JDK 1.1 source code:

/* * @(#)KeyPairGenerator.java 1.12 01/12/10 * * Copyright 2002 Sun Microsystems, Inc. All rights reserved. * SUN PROPRIETARY/CONFIDENTIAL. Use is subject to license terms. */ package java.security; /** * The KeyPairGenerator class is used to generate pairs of * public and private keys. Key generators are constructed using the * <code>getInstance</code> factory methods (static methods that * return instances of a given class). * * <p>Key generation is an area that sometimes * does not lend itself well to algorithm independence. For example, * it is possible to generate a DSA key pair specifying key family * parameters (p, q and g), while it is not possible to do so for * an RSA key pair. That is, those parameters are applicable to DSA * but not to RSA. * * <P>There are therefore two ways to generate a key pair: in an * algorithm-independent * manner, and in an algorithm-specific manner. The only difference * between the two is the initialization of the object. * * <p>All key pair generators share the concepts of a "strength" and a * source of randomness. The measure of strength is universally shared * by all algorithms, * though it is interpreted differently for different algorithms. * The <a href = "#initialize ">initialize</a> method in this * KeyPairGenerator class * takes these two universally shared * types of arguments. * * <p>Since no other parameters are specified when you call this * algorithm-independent <code>initialize</code> * method, all other values, such as algorithm parameters, public * exponent, etc., are defaulted to standard values. * * <P> * It is sometimes desirable to initialize a key pair generator object * using algorithm-specific semantics. For example, you may want to * initialize a DSA key generator for a given set of parameters * <code>p</code>, <code>q</code> and <code>g</code>, * or an RSA key generator for a given public exponent. * * <P> * This is done through algorithm-specific standard interfaces. Rather than * calling the algorithm-independent KeyPairGenerator <code>initialize</code> * method, the key pair generator is cast to an algorithm-specific interface * so that one of its specialized parameter initialization methods can be * called. An example is the DSAKeyPairGenerator interface (from * <code>java.security.interfaces</code>). * * <p>See <a href = * "../guide/security/CryptoSpec.html#KPG">The KeyPairGenerator Class</a> * in the "Java Cryptography Architecture API Specification & Reference" * for more information and examples. * * @see java.security.interfaces.DSAKeyPairGenerator */ public abstract class KeyPairGenerator { private String algorithm; /** * Creates a KeyPairGenerator object for the specified algorithm. * * @param algorithm the standard string name of the algorithm. * See Appendix A in the <a href= * "../guide/security/CryptoSpec.html#AppA"> * Java Cryptography Architecture API Specification & Reference </a> * for information about standard algorithm names. */ protected KeyPairGenerator(String algorithm) { this.algorithm = algorithm; } /** * Returns the standard name of the algorithm for this key generator. * See Appendix A in the <a href= * "../guide/security/CryptoSpec.html#AppA"> * Java Cryptography Architecture API Specification & Reference </a> * for information about standard algorithm names. * * @return the standard string name of the algorithm. */ public String getAlgorithm() { return algorithm; } /** * Generates a KeyPairGenerator object that implements the algorithm * requested, as available in the environment. * * @param algorithm the standard string name of the algorithm. * See Appendix A in the <a href= * "../guide/security/CryptoSpec.html#AppA"> * Java Cryptography Architecture API Specification & Reference </a> * for information about standard algorithm names. * * @return the new KeyPairGenerator object. * * @exception NoSuchAlgorithmException if the algorithm is * not available in the environment. */ public static KeyPairGenerator getInstance(String algorithm) throws NoSuchAlgorithmException { try { return (KeyPairGenerator)Security.getImpl(algorithm, "KeyPairGenerator", null); } catch(NoSuchProviderException e) { throw new InternalError("please send a bug report via " + System.getProperty("java.vendor.url.bug")); } } /** * Generates a KeyPairGenerator object implementing the specified * algorithm, as supplied from the specified provider, * if such an algorithm is available from the provider. * * @param algorithm the standard string name of the algorithm. * See Appendix A in the <a href= * "../guide/security/CryptoSpec.html#AppA"> * Java Cryptography Architecture API Specification & Reference </a> * for information about standard algorithm names. * * @param provider the string name of the provider. * * @return the new KeyPairGenerator object. * * @exception NoSuchAlgorithmException if the algorithm is * not available from the provider. * * @exception NoSuchProviderException if the provider is not * available in the environment. * * @see Provider */ public static KeyPairGenerator getInstance(String algorithm, String provider) throws NoSuchAlgorithmException, NoSuchProviderException { return (KeyPairGenerator)Security.getImpl(algorithm, "KeyPairGenerator", provider); } /** * Initializes the key pair generator for a certain strength. * * @param strength the strength of the key.
