From golangci-lint: > SA1019: rand.Read has been deprecated since Go 1.20 because it >shouldn't be used: For almost all use cases, crypto/rand.Read is more >appropriate. (staticcheck) > SA1019: rand.Seed has been deprecated since Go 1.20 and an alternative >has been available since Go 1.0: Programs that call Seed and then expect >a specific sequence of results from the global random source (using >functions such as Int) can be broken when a dependency changes how >much it consumes from the global random source. To avoid such breakages, >programs that need a specific result sequence should use >NewRand(NewSource(seed)) to obtain a random generator that other >packages cannot access.
