Functions

func GenerateResponseCode

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

GenerateResponseCode 生成密码

func GetChallenge

func GetChallenge() int64

GetChallenge 获取时间token

func GetTotpCode

func GetTotpCode(secret string, codeLength int) []string

GetTotpCode 获取totpcode, 这里会生成3个code，当前时间，前30s,后30s 为了预防客户端跟服务端的时间差太大

func NewTotpToken

func NewTotpToken(length int) string

NewTotpToken 新生成token

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 base32 解码

func DefaultNewBase32Decode

func DefaultNewBase32Decode() *Base32Decode

DefaultNewBase32Decode 默认base32解码器

func NewBase32Decode

func NewBase32Decode(encode string) *Base32Decode

NewBase32Decode 新建base32解码器

func (*Base32Decode) Decode

func (dec *Base32Decode) Decode(encoded string) ([]byte, error)

Decode 解码
