To uninstall radare2, run the following command from the command line or from PowerShell:


Deployment Method:


This applies to both open source and commercial editions of Chocolatey.

1. Enter Your Internal Repository Url

(this should look similar to https://community.chocolatey.org/api/v2/)

2. Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Copy Your Script

choco upgrade radare2 -y --source="'INTERNAL REPO URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade radare2 -y --source="'INTERNAL REPO URL'" 

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

Radare2: Unix-Like Reverse Engineering Framework

Next release will be 5.5.0, current git is 5.4.3 and the latest packaged version(s) See the Release downloads page.

r2 is a rewrite from scratch of radare. It provies a set of libraries, tools and
plugins to ease reverse engineering tasks.

The radare project started as a simple command-line hexadecimal editor focused on
forensics, over time more features were added to support a scriptable command-line
low level tool to edit from local hard drives, kernel memory, programs, remote gdb
servers and be able to analyze, emulate, debug, modify and disassemble any binary.

Some of the most installed packages are:

  • r2ghidra the native ghidra decompiler plugin: pdg command
  • esilsolve symbolic execution r2 plugin based on esil and z3
  • r2dec decompiler based on r2 written in js pdd
  • r2frida the frida io plugin r2 frida://0
  • iaito - official graphical interface (Qt)

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).
