gotopt: A basic package to generate/validate TOPT (RFC6238)
Usage
package main
import(
"fmt"
"github.com/sheepkiller/gotopt"
"os"
"time"
)
func main() {
token, remain, err := gotopt.GetTOPT("AAAAAAAAAAAAAAAA", 6, "sha1")
if err != nil {
fmt.Printf("Error: %s\n", err.Error())
os.Exit(1)
}
fmt.Printf("TOPT: %s will expire in %d seconds\n", token, remain)
valid, err:= gotopt.ValidateTOPT("AAAAAAAAAAAAAAAA", 6, "sha1", token, 0)
if valid {
fmt.Println("token is valid")
}
time.Sleep(30 * time.Second)
valid, err= gotopt.ValidateTOPT("AAAAAAAAAAAAAAAA", 6, "sha1", token, 0)
if valid {
fmt.Println("token is valid")
} else {
fmt.Println("token is invalid")
}
valid, err= gotopt.ValidateTOPT("AAAAAAAAAAAAAAAA", 6, "sha1", token, 1)
if valid {
fmt.Println("token is valid")
} else {
fmt.Println("token is invalid")
}
}

Functions ¶
func GetTOPT ¶
func GetTOPT(str_secret string, digits int, shaX string) (str_token string, remain uint64, err error)
Generate a TOPT
str_secret: secret key (strict base32) digits: number of digits (from 4 to 8) shaX: hash function (SHA1, SHA256, or SHA512)
returns:
str_token: string representation of token (type string) remain: remaining validity time (type uint64) err: error
func ValidateTOPT ¶
func ValidateTOPT(str_secret string, digits int, shaX string, topt string, interval int) (valid_token bool, err error)
Validate a TOPT
str_secret: secret key (strict base32) digits: number of digits (from 4 to 8) shaX: hash function (SHA1, SHA256, or SHA512) topt: token to validate (type string) interval: validate against previous interval window (30s)
returns
valid_token: boolean : true if valid, false if not err: error
XXX: need test
