Renaming results for a demonstration assembly in Babel Desktop

Enterprise

A single-developer license for the developer's own Windows computer, with Babel Desktop for Windows, the command-line tools and the MSBuild task. Build servers, macOS and Linux need Ultimate.

Ultimate

A site license for Windows, macOS and Linux. Includes Desktop, NuGet packages, build server integration, Babel Encrypt and the additional Ultimate protections.

Maintenance that follows your builds

A perpetual license keeps working for builds released while its maintenance was active. Renew maintenance to cover newer builds; your covered version continues to work.

01 / BABEL OBFUSCATOR 12

Keep the behavior. Change the names.

Rename types, methods, properties and fields while preserving the references your application needs. Use exclusion rules for public APIs, reflection and serialization, and keep map files for diagnosing production issues.

02 / BABEL OBFUSCATOR 12

Make the execution path harder to follow.

Chain: Ultimate

Transform method bodies without changing their intended behavior. Ultimate adds chain control flow in Babel 12, with chained-state dispatch and runtime state that complicates reconstruction of the original flow.

03 / BABEL OBFUSCATOR 12

Protect strings, resources and method bodies.

Stream strings: Ultimate

Encrypt strings, values, resources and MSIL code with controls that let you balance protection and runtime cost. Ultimate adds stream string encryption. Dynamic proxy introduces indirection around selected method calls.

04 / BABEL OBFUSCATOR 12

Verify the application that runs.

Mobile integrity: Ultimate

Add anti-tampering checks to detect changed assemblies. Ultimate can also validate Android signing information and iOS bundle or team identity. These protections add checks to your application; they do not make reverse engineering impossible.

05 / BABEL OBFUSCATOR 12

Keep assemblies and rules together.

Merge or embed dependencies and configure cross-assembly references on the project canvas. Keep the project and its XML rules in source control, then use the CLI or MSBuild task in your build pipeline.

06 / BABEL OBFUSCATOR 12

Make sense of an obfuscated stack trace.

Use the original map file to decode a stack trace back to the names you know. Inspect warnings before shipping and review protection statistics after each run.
