The rand package — utilities for generating random values in Go using only the Go standard library.

It offers three main functions:

• 🔐 RandomInt(min, max) — cryptographically secure random integer
• 🧬 TraceID() — pseudo-random alphanumeric string (16 characters)
• 🔢 AlgoDefault(start, end) — secure random number returned as a string

Generates a secure random integer in the range [min, max).

package main

import (
	"fmt"
	"log"

	"github.com/jeffotoni/quick/rand"
)

func main() {
	n, err := rand.RandomInt(10, 20)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println("Random number generated:", n)
}

Generates a 16-character alphanumeric ID for tracing or temporary identification.

package main

import (
	"fmt"

	"github.com/jeffotoni/quick/rand"
)

func main() {
	id := rand.TraceID()
	fmt.Println("Trace ID generated:", id)
}

Generates a secure random number between start and end (as a string).

package main

import (
	"fmt"

	"github.com/jeffotoni/quick/rand"
)

func main() {
	msgID := rand.AlgoDefault(1000, 9999)
	fmt.Println("Msg ID generated:", msgID)
}
