|
### How to enrol a new token
|
||
|
|
|
||
|
|
```go
|
||
|
|
app_id := "http://localhost"
|
||
|
|
|
||
|
|
// Send registration request to the browser.
|
||
|
|
c, _ := NewChallenge(app_id, []string{app_id})
|
||
|
|
req, _ := c.RegisterRequest()
|
||
|
|
|
||
|
|
// Read response from the browser.
|
||
|
|
var resp RegisterResponse
|
||
|
|
reg, err := Register(resp, c, nil)
|
||
|
|
if err != nil {
|
||
|
|
// Registration failed.
|
||
|
|
}
|
||
|
|
|
||
|
|
// Store registration in the database.
|
||
|
|
```
|
||
|
|
|
||
|
|
### How to perform an authentication
|
||
|
|
|
||
|
|
```go
|
||
|
|
// Fetch registration and counter from the database.
|
||
|
|
var reg Registration
|
||
|
|
var counter uint32
|
||
|
|
|
||
|
|
// Send authentication request to the browser.
|
||
|
|
c, _ := NewChallenge(app_id, []string{app_id})
|
||
|
|
req, _ := c.SignRequest(reg)
|
||
|
|
|
||
|
|
// Read response from the browser.
|
||
|
|
var resp SignResponse
|
||
|
|
newCounter, err := reg.Authenticate(resp, c, counter)
|
||
|
|
if err != nil {
|
||
|
|
// Authentication failed.
|
||
|
|
}
|
||
|
|
|
||
|
|
// Store updated counter in the database.
|
||
|
|
```
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
```
|
||
|
|
$ go get github.com/tstranex/u2f
|
||
|
|
```
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
See u2fdemo/main.go for an full example server. To run it:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ go install github.com/tstranex/u2f/u2fdemo
|
||
|
|
$ ./bin/u2fdemo
|
||
|
|
```
|
||
|
|
|
||
|
|
Open https://localhost:3483 in Chrome.
|
||
|
|
Ignore the SSL warning (due to the self-signed certificate for localhost).
|
||
|
|
You can then test registering and authenticating using your token.

||
|

|
## Changelog
|
||
|
|
|
||
|
|
- 2016-12-18: The package has been updated to work with the new
|
||
|
|
U2F Javascript 1.1 API specification. This causes some breaking changes.
|
||
|
|
|
||
|
|
`SignRequest` has been replaced by `WebSignRequest` which now includes
|
||
|
|
multiple registrations. This is useful when the user has multiple devices
|
||
|
|
registered since you can now authenticate against any of them with a single
|
||
|
|
request.
|
||
|
|
|
||
|
|
`WebRegisterRequest` has been introduced, which should generally be used
|
||
|
|
instead of using `RegisterRequest` directly. It includes the list of existing
|
||
|
|
registrations with the new registration request. If the user's device already
|
||
|
|
matches one of the existing registrations, it will refuse to re-register.
|
||
|
|
|
||
|
|
`Challenge.RegisterRequest` has been replaced by `NewWebRegisterRequest`.
