From b0fa81eea9a270f23d6ad67ca7a6d25c18d20da1 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sat, 16 Jul 2005 01:27:14 +0000 Subject: Major merge with Classpath. Removed many duplicate files. * HACKING: Updated.x * classpath: Imported new directory. * standard.omit: New file. * Makefile.in, aclocal.m4, configure: Rebuilt. * sources.am: New file. * configure.ac: Run Classpath configure script. Moved code around to support. Disable xlib AWT peers (temporarily). * Makefile.am (SUBDIRS): Added 'classpath' (JAVAC): Removed. (AM_CPPFLAGS): Added more -I options. (BOOTCLASSPATH): Simplified. Completely redid how sources are built. Include sources.am. * include/Makefile.am (tool_include__HEADERS): Removed jni.h. * include/jni.h: Removed (in Classpath). * scripts/classes.pl: Updated to look at built classes. * scripts/makemake.tcl: New file. * testsuite/libjava.jni/jni.exp (gcj_jni_compile_c_to_so): Added -I options. (gcj_jni_invocation_compile_c_to_binary): Likewise.

Key factories are used to convert keys (opaque cryptographic keys of type - * {@link Key}) into key specifications (transparent representations of the - * underlying key material), and vice versa.

- * - *

Key factories are bi-directional. That is, they allow you to build an - * opaque key object from a given key specification (key material), or to - * retrieve the underlying key material of a key object in a suitable format.

- * - *

Multiple compatible key specifications may exist for the same key. For - * example, a DSA public key may be specified using {@link - * java.security.spec.DSAPublicKeySpec} or {@link - * java.security.spec.X509EncodedKeySpec}. A key factory can be used to - * translate between compatible key specifications.

- * - *

The following is an example of how to use a key factory in order to - * instantiate a DSA public key from its encoding. Assume Alice has - * received a digital signature from Bob. Bob also sent her his public key (in - * encoded format) to verify his signature. Alice then performs the following - * actions: - * - * 

- *  X509EncodedKeySpec bobPubKeySpec = new X509EncodedKeySpec(bobEncodedPubKey);
- *  KeyFactory keyFactory = KeyFactory.getInstance("DSA");
- *  PublicKey bobPubKey = keyFactory.generatePublic(bobPubKeySpec);
- *  Signature sig = Signature.getInstance("DSA");
- *  sig.initVerify(bobPubKey);
- *  sig.update(data);
- *  sig.verify(signature);
