func GenerateRandomToken(length int) string

GenerateRandomToken generates a token of the specified length

func GenerateSHA1

func GenerateSHA1(reader io.Reader) string

GenerateSHA1 generates a sha1 hash for the specified reader

func ObjectIDIntersect

func ObjectIDIntersect(a []primitive.ObjectID, b []primitive.ObjectID) bool

ObjectIDIntersect checks whether slice a contains any element of slice b vice versa
