import "github.com/ory-am/common/rand/numeric"
import "fmt"

func main() {
    fmt.Printf("%d", numeric.Int64())
    fmt.Printf("%d", numeric.UInt64())
    fmt.Printf("%d", numeric.Int32())
    fmt.Printf("%d", numeric.UInt32())
}

Create a random rune sequence / string

Create a random string using crypto/rand.Read:

import "github.com/ory-am/common/rand/sequence"
import "fmt"

func main() {
    allowed := []rune("abcdefghijklmnopqrstuvwxyz")
    length := 10
    seq, err := sequence.RuneSequence(length, allowed)

    fmt.Printf("%s", seq)
    fmt.Printf("%s", string(seq))
