Functions

func GenerateAlphanumericCode

func GenerateAlphanumericCode(length uint) (string, error)

GenerateAlphanumericCode will generate an alpha numberic code. It uses the length to estimate how many bytes of randomness will base64 encode to that length string. For example 16 character string requires 12 bytes.

func GenerateCode

func GenerateCode(length uint) (string, error)

GenerateCode creates a new OTP code.

Types

type Request

type Request struct {
	DB             *database.Database
	RealmID        uint
	ShortLength    uint
	ShortExpiresAt time.Time
	LongLength     uint
	LongExpiresAt  time.Time
	TestType       string
	SymptomDate    *time.Time
	MaxSymptomAge  time.Duration
	IssuingUser    *database.User
	IssuingApp     *database.AuthorizedApp
}

Request represents the parameters of a verification code request.

func (*Request) Issue

func (o *Request) Issue(ctx context.Context, retryCount uint) (string, string, string, error)

Issue will generate a verification code and save it to the database, based on the paremters provided. It returns the short code, long code, a UUID for accessing the code, and any errors.
