    Open source obfuscation tool for .NET assemblies

    Obfuscar is an open-source .NET obfuscator released under MIT license. It provides basic obfuscation features that help secure secrets in a .NET assembly. An obfuscation tool designed for most .NET developers. Hide everything private, while keep everything public. You can achieve such simply via default settings. Hide class/method/property/event names that you don't want to expose. This is irreversible. String contents can be compressed so that end users won't easily learn them. However, this is reversible by certain tools.

    JS Beautifier

    JS Beautifier

    Beautifier for javascript

    This little beautifier will reformat and re-indent bookmarklets, ugly JavaScript, unpack scripts packed by Dean Edward’s popular packer, as well as partly deobfuscate scripts processed by the npm package javascript-obfuscator. All of the source code is completely free and open, available on GitHub under MIT licence, and we have a command-line version, python library and a node package as well. You may install the NPM package js-beautify. When installed globally, it provides an executable js-beautify script. As with the Python script, the beautified result is sent to stdout unless otherwise configured. You can also use js-beautify as a node library (install locally, the npm default). The beautifier can be added on your page as web library. JS Beautifier is hosted on two CDN services: cdnjs and rawgit. You can beautify javascript using JS Beautifier in your web browser, or on the command-line using node.js or python.

    Mixin

    Mixin

    Mixin is a trait/mixin and bytecode weaving framework for Java

    Mixin is a trait/mixin framework for Java using ASM and hooking into the runtime classloading process via a set of pluggable built-in or user-provided services. Built-in services currently support Mojang's LegacyLauncher system, though this is deprecated in favor of ModLauncher by cpw, which has greater extensibility and has support for Java 8 and later. Additional documentation for individual features and annotations can be found in the extensive Javadoc. For additional help use the channel #mixin on the Sponge Discord Server. For handling obfuscation tasks, Mixin provides an Annotation Processor which works at compile time to generate obfuscation mappings for your toolchain to apply. If using Gradle 5 or later, annotation processors are no longer automatically loaded from compile configurations and must be specified explicitly via annotationProcessor configurations.

    Hikari

    Hikari

    LLVM Obfuscator

    All releases prior to and including LLVM8 are signed using this PGP Key from Naville. Verifiable on his Keybase. Security is not now, and will never be based purely on Obscurity. The "Security Companies" might say so to sell more of their products. But no, binary obfuscation won't magically fix all your exploits and bugs, (If not introducing more). Designing an Obfuscator is hard, and keeping the source open definitely leaks the pattern to crackers which could potentially make the crackers' life easier if they have the right skillset. While every reasonable attempt has been made in Hikari to reduce such patterns from appearing, however, with overkill weapons like symbolic execution, binary obfuscation can still be defeated much easier, even so-called VM-based obfuscation. DOI 10.1145/2991079.2991114 explained this in great detail. I would implement a few anti-SE mechanisms in the future in an attempt to cause (even) more trouble to attackers, though.

    Simplify

    Simplify

    Android virtual machine and deobfuscator

    Simplify virtually executes an app to understand its behavior and then tries to optimize the code so that it behaves identically but is easier for a human to understand. Each optimization type is simple and generic, so it doesn't matter what specific type of obfuscation is used. Provides a virtual machine sandbox for executing Dalvik methods. After executing a method, it returns a graph containing all possible register and class values for every execution path. It works even if some values are unknown, such as file and network I/O. For example, any if or switch conditional with an unknown value results in both branches being taken. Analyzes the execution graphs from smalivm and applies optimizations such as constant propagation, dead code removal, unreflection, and some peephole optimizations. These are fairly simple, but when applied together repeatedly, they'll decrypt strings, remove reflection, and greatly simplify code. It does not rename methods and classes.

    AntiLVL Reloaded

    AntiLVL Reloaded

    AntiLVL Android LVL Hack Remove License verification of Android

    AntiLVL Reloaded. Major update to AntiLVL antilvl 1.4.0.How to Remove License verification of Android Apps AntiLVL's purpose is to subvert standard license protection methods such as the Android License Verification Library (LVL), Amazon Appstore DRM and Verizon DRM. It also disables many anti-cracking and anti-tampering protection methods. Because every implementation of the LVL is potentially (and often is) quite different, it's not possible to automate patching in every case. It will not always work. However, it has been designed to get around obfuscation and to apply many variations. AntiLVL is a configurable Smali code patcher with rules defined in user-modifiable XML files stored inside the jar called fingerprints. Brief summary of how it works: Decompiles the Apk Perform regular expression matching Carrie out defined modifications Recompile, update classes.dex Resign and zipalign Remove Google Play Store Check
