This library supports the parsing and verification as well as the generation and signing of JWTs. Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.
|
||||
|
||||
## Parse and Verify
|
||||
## Examples
|
||||
|
||||
Parsing and verifying tokens is pretty straight forward. You pass in the token and a function for looking up the key. This is done as a callback since you may need to parse the token to find out what signing method and key was used.
|
||||
See [the project documentation](https://godoc.org/github.com/dgrijalva/jwt-go) for examples of usage:
|
||||
|
||||
```go
|
||||
token, err := jwt.Parse(myToken, func(token *jwt.Token) (interface{}, error) {
|
||||
// Don't forget to validate the alg is what you expect:
|
||||
if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok {
|
||||
return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"])
|
||||
}
|
||||
return myLookupKey(token.Header["kid"]), nil
|
||||
})
|
||||
|
||||
if err == nil && token.Valid {
|
||||
deliverGoodness("!")
|
||||
} else {
|
||||
deliverUtterRejection(":(")
|
||||
}
|
||||
```
|
||||
|
||||
## Create a token
|
||||
|
||||
```go
|
||||
// Create the token
|
||||
token := jwt.NewWithClaims(jwt.SigningMethodHS256, jwt.MapClaims{
|
||||
"foo": "bar",
|
||||
"exp": time.Now().Add(time.Hour * 72).Unix(),
|
||||
})
|
||||
// Sign and get the complete encoded token as a string
|
||||
tokenString, err := token.SignedString(mySigningKey)
|
||||
```
