Fast, dependable universally unique ids

Gouid

Use Gouid to create cryptographically secure random IDs. IDs can be byte slices or strings, both generated with just one allocation (see benchmarks below).

Documentation

For full documentation see pkg.go.dev.

Example

package main

import (
	"fmt"
	
	"github.com/twharmon/gouid"
)

func main() {
	a := gouid.String(8, gouid.Secure32Char)
	fmt.Println(a) // mp1nq34p

	b := gouid.String(16, gouid.Secure64Char)
	fmt.Println(b) // h-SoemLKa_QtoXgh

	c := gouid.Bytes(16)
	fmt.Println(c) // [244 188 217 137 122 245 94 126 80 119 87 170 6 178 228 179]
}
