Obfuscate Go builds (moved to burrowers/garble)
GO111MODULE=on go get mvdan.cc/garble
Obfuscate Go code by wrapping the Go toolchain. Requires Go 1.15 or later, since Go 1.14 uses an entirely different object format.
garble build [build flags] [packages]
garble -hfor up to date usage information.
Produce a binary that works as well as a regular build, but that has as little information about the original source code as possible.
The tool is designed to be:
cmd/go, to support modules and build caching
The tool wraps calls to the Go compiler and linker to transform the Go build, in order to:
-literalsflag is given
-tinyflag is given
By default, the tool garbles the packages under the current module. If not running in module mode, then only the main package is garbled. To specify what packages to garble, set
GOPRIVATE, documented at
go help module-private.
Most of these can improve with time and effort. The purpose of this section is to document the current shortcomings of this tool.
Exported methods are never garbled at the moment, since they could be required by interfaces and reflection. This area is a work in progress.
Functions implemented outside Go, such as assembly, aren't garbled since we currently only transform the input Go source.
Go plugins are not currently supported; see #87.
-tinyflag is passed, extra information is stripped from the resulting Go binary. This includes line numbers, filenames, and code in the runtime the prints panics, fatal errors, and trace/debug info. All in all this can make binaries 6-10% smaller in our testing.
-tinyis passed, no panics, fatal errors will ever be printed, but they can still be handled internally with
recoveras normal. In addition, the
GODEBUGenvironmental variable will be ignored.
