internal/scan: add binary extract mode

The extract mode spits out a json blob representing the minimal
representation of a Go binary needed for govulncheck vulnerability
detection. binary mode accepts both a Go binary and this representation
as an input.

The contents of extract should be regarded as a blob. The users of this
flag should not rely on its representation. It might change in the

Go Vulnerability Management

Go Reference

Go's support for vulnerability management includes tooling for analyzing your codebase and binaries to surface known vulnerabilities in your dependencies. This tooling is backed by the Go vulnerability database, which is curated by the Go security team. Go’s tooling reduces noise in your results by only surfacing vulnerabilities in functions that your code is actually calling.

You can install the latest version of govulncheck using go install

go install

Then, run govulncheck inside your module:

govulncheck ./...

See the govulncheck tutorial to get started, and for more information about Go's support for vulnerability management. The API documentation can be found at
