The industry's most trusted decompilers. ⏎

pseudocode-1

High-quality, readable, and maintainable pseudocode.

IDA decompilers focus on delivering code that is readable, maintainable, and semantically similar to the original source code thanks to high-level abstractions, semantic preservation, readability, type inference, structure recovery and more.

Metadata about well-known functions. At your fingertips.

The Public Lumina server, maintained by Hex-Rays, tracks metadata for well-known functions, such as names, or operand types. Your IDA instance exchanges only hash values and metadata with the Public Lumina server, avoiding the transfer of sensitive byte patterns through the network.

If you prefer to keep control over your metadata, enable our Private Lumina add-on to use your own self-hosted Lumina server.

Deobfuscation ⏎

Make sense of obfuscated binaries with gooMBA

IDA Pro greatly simplifies the workflow of reverse-engineers dealing with obfuscated binaries, especially those involving Mixed Boolean-Arithmetic (MBA) expressions. The gooMBA plug-in ships with IDA Pro and combines algebraic and program synthesis techniques with smart heuristics for best-in-class deobfuscation performance. It integrates directly into the Hex-Rays decompilers and provides a bridge to an SMT-solver that can prove the correctness of simplifications.

    FAQs

    Frequently asked questions

    You’ve got questions. We have answers!

    Can I change the selected decompilers after the license activation?

    No. Once the decompilers are assigned to your license before activation, they cannot be changed during your subscription period. If you upgrade to a higher plan during your subscription period, you will be then prompted to select additional decompilers according to the chosen plan.

    Check more details about the decompilers assignment in our FAQ.

     

    Is there a free trial version of IDA Pro?

    Although we currently do not offer the trial version of IDA Pro, we encourage you to try IDA Free to check the basic IDA capabilities.

    I currently have IDA Pro 8.x, what are my options to get to IDA 9?

    You have two options:

    • If your perpetual license is in active support, you do not need to purchase a subscription to access IDA 9 under the new subscription model. Your active license allows you to receive a free subscription to IDA 9! To start using IDA 9 today you can access the installer in the new customer portal at my.hex-rays.com. There you can request a license key for your free subscription. Please note that the license key for your free IDA 9 subscription will expire at the end of your active support period. You can find detailed instructions on how to upgrade to IDA 9 here. 
    • If your perpetual license has run out of support, or your support period is about to end, you can select a plan here and upgrade within our customer portal, my.hex-rays.com. For any questions or doubt, do not hesitate to contact sales@hex-rays.com

    What types of licenses are available?

    With IDA Pro plans, we offer three types of licenses to choose from: Named, Computer, or Floating (additional cost).

    License availability depends on the plan. For IDA Home and IDA Free plans, only Named licenses are available.

    Please refer to the license type details for comparison.
