Functions ¶

func GenerateResponseCode ¶

func GenerateResponseCode(secret string, challenge int64, codeLength int) (string, error)

GenerateResponseCode 生成密码

func GetChallenge ¶

func GetChallenge() int64

func ValidTotpCode ¶

func ValidTotpCode(totpToken, totpCode string) bool

ValidTotpCode 验证totp code

Types ¶

type Base32Decode ¶

type Base32Decode struct {
	// contains filtered or unexported fields
}

Base32Decode struct

func DefaultNewBase32Decode ¶

func DefaultNewBase32Decode() *Base32Decode
