KVoD [Key/Value on Disk], a simple, encrypted key/value storage for Go (now using Generics)

Just a sample:

type User struct {
	Name  string
	Email string
}

func main() {
	store := kvod.Init("./db/", "secret")
	userContainer := kvod.CreateContainer[User](db, "users")

	userContainer.Put("1", User{"a username", "user@memorya.org"})

	user, _ := userContainer.Get("1")
	fmt.Println(user)

	userContainer.Delete("1")
}

The idea is to save each value to a file, under the specified path. The value is serialized using gob and encrypted (with AES256 in GCM mode, with PBKDF2 as key derivation function with 10000 iterations).

The key is always a string. The value can be any type gob supports (https://blog.golang.org/gobs-of-data), so structs, strings, slices and more, using Generics.
