You need a key for both generating and parsing tokens. Create a `JwtDerivedKey`
or a `JwtPlaintextKey` and pass it to the `JwtToken` constructor:
use NoccyLabs\SimpleJwt\Key\{JwtDerivedKey,JwtPlaintextKey}
```php
use NoccyLabs\SimpleJwt\Key\{JwtDerivedKey,JwtPlaintextKey}
// Derive a key using secret and salt...
$key = new JwtDerivedKey("secret", "salt");
// ...or use a prepared plaintext key
$key = new JwtPlaintextKey("This Should Be Binary Data..");
// Derive a key using secret and salt...
$key = new JwtDerivedKey("secret", "salt");
// ...or use a prepared plaintext key
$key = new JwtPlaintextKey("This Should Be Binary Data..");
```
### Generating tokens
```php
use NoccyLabs\SimpleJwt\JwtToken;
$tok = new JwtToken($key);
$tok->setExpiry("1h");
$tok->claims->add("some/claim/MaxItems", 8);
use NoccyLabs\SimpleJwt\JwtToken;
$tok = new JwtToken($key);
$tok->setExpiry("1h");
$tok->claims->add("some/claim/MaxItems", 8);
$str = $tok->getSignedToken();
$str = $tok->getSignedToken();
```
### Parsing tokens
Parsing is done by passing the raw token as the 2nd parameter
use NoccyLabs\SimpleJwt\JwtToken;
```php
use NoccyLabs\SimpleJwt\JwtToken;
$str = "...received token...";
$str = "...received token...";
$tok = new JwtToken($key, $str);
$tok = new JwtToken($key, $str);
if (!$tok->isValid()) {
// This check works, but using the validator might be better
}
if (!$tok->isValid()) {
// This check works, but using the validator might be better
}
// Using ->has() follwed by ->get() is one way
if ($tok->claims->has("some/claim/MaxItems")) {
// The claim exists, we can get the value (if any)
$val = $tok->claims->get("some/claim/MaxItems");
}
// Using ->has() follwed by ->get() is one way
if ($tok->claims->has("some/claim/MaxItems")) {
// The claim exists, we can get the value (if any)
$val = $tok->claims->get("some/claim/MaxItems");
}
// You can also use valueOf() to return a default value if needed
$val = $tok->claims->valueOf("some/claim/MaxItems", 64);
// You can also use valueOf() to return a default value if needed
$val = $tok->claims->valueOf("some/claim/MaxItems", 64);
```
### Validating tokens
use NoccyLabs\SimpleJwt\Validator\JwtValidator;
```php
use NoccyLabs\SimpleJwt\Validator\JwtValidator;
$validator = new JwtValidator();
// Require that some claim exists
$validator
->requireIssuer("api.issuer.tld")
->requireAudience(["api.issuer.tld", "foo.issuer.tld"])
->addRequiredClaim("some/required/Claim");
$validator = new JwtValidator();
// Require that some claim exists
$validator
->requireIssuer("api.issuer.tld")
->requireAudience(["api.issuer.tld", "foo.issuer.tld"])
->addRequiredClaim("some/required/Claim");
try {
// Pass a JwtToken to validateToken()...
$valid = $validator->validateToken($tok);
// ...or pass a JwtKeyInterface and the raw string to validate()
$valid = $validator->validate($key, $tokenstr);
}
catch (JwtValidatorException $e) {
// validation failed
}
try {
// Pass a JwtToken to validateToken()...
$valid = $validator->validateToken($tok);
// ...or pass a JwtKeyInterface and the raw string to validate()
$valid = $validator->validate($key, $tokenstr);
}
catch (JwtValidatorException $e) {
// validation failed
}
```
