Module lockfile 

go.sum lock file parsing.

Parses go.sum files to extract resolved dependency versions. go.sum contains checksums for all modules used in a build, including transitive dependencies and multiple versions.

go.sum Format

Each line in go.sum has the format:

module_path version hash

Example:

github.com/gin-gonic/gin v1.9.1 h1:4idEAncQnU5cB7BeOkPtxjfCSye0AAm1R0RVIqJ+Jmg=
github.com/gin-gonic/gin v1.9.1/go.mod h1:hPrL9t9/HBtKc7e/Q7Nb2nqKqTW8mHZy6E7k8m4dLvs=
golang.org/x/sync v0.5.0 h1:60k92dhOjHxJkrq...
golang.org/x/sync v0.5.0/go.mod h1:RxMgew5V...

Line Types

• Lines ending with /go.mod are module file checksums (skipped for version resolution)
• Lines with h1:hash are actual module content checksums (used for version resolution)
• A module may appear multiple times with different versions
