http://www.retrologic.com/ Retrologic provides custom software solutions, and is the home of the Open Source RetroGuard Obfuscator for Java. en-us Copyright 1998-2007 Retrologic Systems Fri, 9 Mar 2007 00:00:00 GMT http://www.retrologic.com/capture-main.html RetroCapture is a CAPTCHA generator, written in 100% Java. RetroCapture Pro can be integrated with your web-application in several ways: batch image generation; server-mode generation; or direct Java library integration. RetroCapture has no dependence on the Java AWT, making it suitable for use in 'headless' server-side environments. Fri, 9 Mar 2007 00:00:00 GMT http://retrologic.com/newsletter_20070228.html Support added for Java SE 6, including the new code attribute StackMapTable. Unsupported versions of the class file format now gives a warning instead of stopping the obfuscation process. Trim bug-fix: methods could be incorrectly trimmed if accessed only through base class references. Readme.txt now includes 'Quick Start' documentation. Wed, 28 Feb 2007 00:00:00 GMT http://www.retrologic.com/capture-main.html Fixed bug relating to resource loading on certain systems. Various image quality and speed improvements. Mon, 26 Jun 2006 00:00:00 GMT http://www.retrologic.com/capture-main.html RetroCapture Lite is a CAPTCHA generator, written in 100% Java and with absolutely no dependence on the Java AWT. This makes it suitable for use in 'headless' server-side environments. Wed, 17 May 2006 00:00:00 GMT http://retrologic.com/newsletter_20060331.html '.option Repackage' safe repackaging of classes into top-level packages, reducing obfuscated size. '.option Trim' available in both GPL and commercial versions. '.option Generic' added, currently equivalent to '.attribute Signature'. RGdefault utility added, outputs internal default script. '.nowarn <class>' added to script format, suppression of reflection warnings from log. '.option MapClassString' bug-fix for certain inner classes. Error-handling improved when duplicate classfiles are detected in the input jar. Documentation updates. Fri, 31 Mar 2006 00:00:00 GMT http://retrologic.com/newsletter_20050825.html Fixed an interaction between negation commands (!class / !method / !field) and certain multiple inheritance graphs that caused a non-fatal failure to rename some methods and fields, when renaming should be possible. Added display of version number to RetroGuard usage message. Thu, 25 Aug 2005 00:00:00 GMT http://retrologic.com/newsletter_20050727.html Additional checks to prevent RetroGuard terminating with a warning on certain JDK1.4.2 classfiles. Tue, 19 Jul 2005 00:00:00 GMT http://retrologic.com/newsletter_20050615.html '.option Trim' added enabling unused methods, fields, and even whole classes to be trimmed by RetroGuard. This can lead to significant reduction in jar size, particularly in cases where only a few classes are being used from a larger library. Wed, 15 Jun 2005 00:00:00 GMT http://retrologic.com/newsletter_20050615.html 'RGtrace' tool added, helping to interpret obfuscated stack traces. '.option LineNumberDebug' added, allowing line number information to be preserved for stack traces without exposing unobfuscated class names within the 'SourceFile' attribute. Wed, 1 Jun 2005 00:00:00 GMT http://retrologic.com/rg-docs-examplergs.html RetroGuard scripting language examples have been extended to cover new features such as: class, method, and field access flags; use of the 'extends' clause; the 'and_class' modifier; use of the wildcards '*' and '**'. Fri, 27 May 2005 00:00:00 GMT http://retrologic.com/newsletter_20050331.html Explicit array bounds checking added to Code attribute parser. Behavior of script entries '!class', '!method' and '!field' changed. These statements no longer force obfuscation of package level identifiers, which in v2.0.1 could lead to unexpected behavior such as the obfuscation of package level identifiers while classes in those packages were preserved from obfuscation. Wed, 30 Mar 2005 00:00:00 GMT http://retrologic.com/newsletter_20050208.html RetroGuard is now available in a dual-licensed format: GPL for non-commercial users, and an annual commercial license for commercial users. Feature upgrades include: Apache Ant tasks; automatic Class.forName()/.class handling; improved script wildcarding; full support for JDK-1.5/JDK-5 Generics, Enumerations, and Annotations; improved handling of serialization and RMI; many other script language improvements. Fri, 4 Feb 2005 00:00:00 GMT http://retrologic.com/retroguard-download.html RetroGuard now compiles under JDK1.5/JDK5. Updated classfile version checking to accept MAJOR_VERSION = 0x31 (49) as used in JDK1.5/JDK5 with default compilation option -source 1.5 Fri, 10 Dec 2004 00:00:00 GMT http://retrologic.com/retroguard-main.html Thank you to everyone who has taken the time to donate to the RetroGuard project. Your contributions help make the RetroGuard for Java obfuscator a high priority and enable further development of RetroGuard. Mon, 29 Nov 2004 00:00:00 GMT http://retrologic.com/retroguard-download.html Added 'Deprecated' to the list of classfile attributes which can be preserved during obfuscation. Use script file syntax: .attribute Deprecated Tue, 23 Nov 2004 00:00:00 GMT http://retrologic.com/jargon-file.html A local mirror of The Jargon File has been added to the Retrologic site. Features specific to this mirror include a no-frames alphabetic index at the top of each page, a 'Random Entry' link, and an RSS feed of random Jargon File entries. Thu, 11 Nov 2004 00:00:00 GMT http://retrologic.com/retroguard-download.html Fixed long-standing bug in handling of manifest file continuation lines. Thanks to Grant Gould for reporting this. Thu, 26 Feb 2004 00:00:00 GMT http://retrologic.com/retroguard-download.html Addition to major bugfix in v1.1.12 regarding JDK1.4-compiled code: implemented interfaces as well as the superclass are now traversed to resolve obfuscated method and field names. Also, System.exit(0) in RetroGuard (removed in v1.1.10) has been added back. For Ant integration (pre-JDK1.4 only), spawn a separate VM for RetroGuard. Sat, 2 Nov 2002 00:00:00 GMT http://retrologic.com/retroguard-download.html Major fix from v1.1.11 regarding JDK1.4-compiled code: Changes to the JDK1.4 compiler from prior versions broke RetroGuard's ability to obfuscate any non-trivial inheritance structure in the code. The symptom was methods and fields defined in superclasses not being found at runtime in obfuscated code. The RetroGuard renaming mechanism has been updated to cope with these JDK1.4 compiler changes. The bug only affected code compiled with JDK1.4 which was only supported recently in RetroGuard v1.1.11, exposing the bug. Tue, 29 Oct 2002 00:00:00 GMT http://retrologic.com/retroguard-download.html Updated classfile version checking to accept MAJOR_VERSION = 0x30 (48) as used in JDK1.4 with compilation option "-source 1.4" Tue, 8 Oct 2002 00:00:00 GMT http://retrologic.com/retroguard-download.html Updated classfile version checking to accept MAJOR_VERSION = 0x2E (46) as used in JDK1.4. Classfile integrity checking now provides more detailed error messages. Removed error check that invalidly triggered on valid (but unusual) identifiers like "XX$$71". System.exit(0) is no longer called on normal termination, to ease integration with tools like Ant. Mon, 7 Oct 2002 00:00:00 GMT
