The Java Binary Enhancement Tool (JBET) is a general Java program analysis and manipulation tool. Existing class files can be disassembled, reassembled, or edited programmatically through the JBET API. JBET can also be used to create new Java class files from scratch. JBET uses a convenient internal representation of all the contents of Java binary (.class) files, allowing the user to edit the classes easily, in a structured manner.

JBET was developed as part of the DARPA Self-Protecting Mobile Agents project under the OASIS and Active Networks programs (contract number N66001-00-C-8602) in order to study automated software obfuscation.

The Java language was chosen for this project because of the (relative) ease of constructing binary editing tools provided by the large amount of type information present in the class files. Our two reports, the Obfuscation Techniques Evaluation Report, and the Obfuscation Report, are available from the download area. The obfuscation tool developed is not part of this release.

JBET was also used in the DARPA/AFRL Survivable Server project (contract number F30602-00-C-0183) to add additional security checks to the Java Standard Library. (The Java SecurityManager API does not support many desirable security checks, such as continued authorization of file accesses after opening.)

JBET was used to replace the native method references in the Java standard library with stubs that call a pluggable security policy. This tool, called Jpolicy, is also available for download at this website. Jpolicy is very incomplete at this time, but may be interesting to those working in Java security or changing the standard library themselves.

The internal representation of Java class files used by JBET is intented to make it easy for programmers to write Java binary code transforms. Each element of Java class files has a corresponding internal data structure: ClassInfo for entire classes, MethodInfo for methods, FieldInfo for fields, Snippit for code blocks, and Instruction for individual instructions. Snippit and Instruction understand Java opcode syntax and semantics, allowing automated creation of valid Java programs. A Java-compatible class verifier is also included.

Some code transforms are difficult to program directly by manipulating Java instructions. For those transforms, a directed acyclic graph (DAG) representation of code is available. In the DAG representation, each basic block has a corresponding DAG, with a set of input and output nodes. Edges in the graph connect "producer" nodes (such as constants, or the result of calculations) to "user" nodes (such as method calls or other calculations). Methods are divided into basic blocks and control flow is stored at the basic block level (possible because Java has only fixed jump targets)

JBET requires a Java 1.4 virtual machine to run, although it can operate on class files from earlier Java versions. The packaging and build environment supplied supports Linux and Windows with Cygwin; however, the build process is simple and could be performed manually on other platforms. Perl is required for regression testing.

Jpolicy requires a Java 1.4 virtual machine to build, either Linux or Windows NT/XP with Cygwin. gcc is required for building on Windows (supplied with Cygwin). The runtime system can be either Java 1.3 or 1.4 (with Suns JVM only), running on Linux or Windows NT/XP. Windows 9x and Windows 2000 may work as well, but have not been tested.

Installation

1. Install jdk 1.4.1.
2. Set CLASSPATH to jdk1.4.1/jre/lib/rt.jar
3. cd src; make
4. If that didnt work, examine the makefile. java or javac may not be in the path.
5. To build a jar file that can be used with "java -jar jbet.jar", run "make jar".
6. If you have perl installed, run the tests with "make test".
Optionally, run "make regen; make test".

Make a symbolic link from jbet3/bin/jbet to somewhere in your path.

Usage

JBET uses the JNI format for class names, and JNI type and method descriptors. For a summary of this syntax, use jbet help syntax. Suns JVM specification may also be helpful.

To look at a class disassembly, use jbet print. Try disassembling a class you have source for, and was built with debug info (-g): jbet -P < classpath > print < classname >. Suns JVM specification has an instruction reference.

LDAP Mailing Lists Access Policy Daemon (MLAPD) is a mailing list manager that uses LDAP (instead of BDB or GDBM) to control list access. Its designed to work in conjunction with Postfix as an access policy delegation daemon. It manages electronic mail discussion and e-newsletter lists. Its goal is to store/read list data on/from LDAP.
It works as a Postfix access policy delegation agent, so it can be installed one time and used by multiple Postfix instances, or installed multiple times and not suffer database access concurrency issues (because it uses LDAP).
Enhancements:
- This can be considered the first stable and usable release.

Nowadays computers and internet are part of our everyday life: work, school, home. Nevertheless we have our private sphere and we are guarding it with restricted areas accessible with passwords. The better the password, the secure your information is. Therefore we need tools to test and to create better, nontrivial passwords.
- the analyser (shows the "strength" of your pass phrase regarding some rules) and the generator (generates a "strong" pass phrase regarding some rules).
More specific information (rules for creating secure passwords, how to use the tool etc.) can be found by following the above links.
Enhancements:
- A MIDLET version for Java-capable mobile devices is now also available.

Java GetOpt library implements option parsing and a common online help behaviour, including an XML format for topics, command, and options (which can be queried with --help --xml) and support for online browsing with --help --browse.

Whats New in This Release:

ï¿1⁄2 The getopt library can now choose the pluggable look and feel of an application with a standard option "--plaf".
ï¿1⁄2 A new file of default options (.prefs/default.options) can specify a set of common default options for all programs using the getopt library, such as the PLAF.

Folder Extension Wizard provides a small extension that Loads extensions from folders (unpacked xpi files).

A wizard is a user interface element where the user is led through a sequence of dialogs. Unlike most modern user interface paradigms, the user is forced to perform the task in a specific sequence.

However, for complex or infrequently performed tasks where the user is unfamiliar with the steps involved, it may make it easier for them to perform the task. In some open source software, wizards are called Druids.

ffmpeg-php is an extension for PHP that adds an easy to use object-oriented API for retrieving information from movies and audio files.
It has methods for returning frames from movie files as images that can be manipulated using PHPs image functions.
This works well for automatically creating thumbnail images from movie files. ffmpeg-php is also useful for reporting the duration and bitrate of audio files (mp3, wma...). ffmpeg-php can access many of the formats supported by ffmpeg.
Main features:
- Simple object oriented interface.
- Has methods to grab frames from movie files and return them as images that can be manipulated using PHPs built-in image functions. This is great for automatically creating thumbnails for movie files.
- Has the ability to use ffmpegs excellent resampling and cropping features on returned images.
- Provides access to data from mp3 files such as duration, bitrate and track meta information.
