//
// When the go command downloads a module zip file or go.mod file into the
// module cache, it computes a cryptographic hash and compares it with a known
// value to verify the file hasn't changed since it was first downloaded. Known
// hashes are stored in a file in the module root directory named go.sum. Hashes
// may also be downloaded from the checksum database depending on the values of
// GOSUMDB, GOPRIVATE, and GONOSUMDB.
