How to use json privatekey

[lovearthhome]

my private key is in such a format, which cannot tobe read by keychain->getPriateKey(*)

how to deal with this private key

{"kty":"RSA","kid":"88483727556929xxxxxxxx9904351185815489","alg":"ES256","n":"ie0IKvKLd7Y3izHcZemdDsVVXg5QtWtGF7XEkILnn66R2\_3a30DikqV409OVL7Hv0ElACgCaBLEgZeGHTcdLE1xxDTna8MMBnBNuMVghvFERCKh8uzpxlQsfcnFd5IFdJWj1x5Tscetrow6lA3h5zYx0rF5TkZzC4DclxgDmITRam0dsHBxr3uk9m9YYBz2mX0ehjY0xxxxlaA4P9OFAO4au9-zcVQop9vLirxdwDedk2p-F9GP6UiQC9V2LTWqkVw\_oPBf9Rlh8Qdi19jA8SeCfzAxJZYlbOTK8dYAFAVEFsvXCFvdaxQefwWFw","e":"AQAB"}

is there any way to put the privatekey json as php constant?

@lovearthhome you're trying to use a JWK, which currently not supported #32. So for now, if you want to use this lib, you'd need to convert the JWK into private/public keys. There're other libraries that support it.

Hi,

No need for another library, you can use that application (PHAR format).

# Download the application
curl -OL https://github.com/web-token/jwt-app/raw/gh-pages/jose.phar
curl -OL https://github.com/web-token/jwt-app/raw/gh-pages/jose.phar.pubkey

# Convert your key
php jose.phar key:convert:pkcs1 '<YOUR JWK HERE>' > your.key

@lcobucci @Spomky
thankyou for your answers, the jwk->pem solved. however, go further, error happens!

when use ECDSA, Error happens as follows:

PHP Fatal error: Uncaught Error: Class 'Mdanter\Ecc\EccFactory' not found in jwt_lcobucci/jwt/vendor/lcobucci/jwt/src/Signer/Ecdsa.php:48

[Ocramius]

For that you will need

jwt/composer.json

Line 32 in 2c2c77f

"mdanter/ecc": "Required to use Elliptic Curves based algorithms."

[lovearthhome]

@Ocramius
use composer require mdanter/ecc and then move the files to where?

[Ocramius]

@lovearthhome no need to move anything

[lovearthhome]

is this right?
[u1@EevX vendor]$ ls autoload.php composer fgrosse lcobucci mdanter

[Ocramius]

Yeap, that should be it 👍

[lovearthhome]

Error happens on:
@Ocramius

PHP Fatal error: Uncaught TypeError: Argument 1 passed to Lcobucci\JWT\Signer\Ecdsa\KeyParser::__construct() must be an instance of Mdanter\Ecc\Math\MathAdapterInterface, instance of Mdanter\Ecc\Math\GmpMath given, called in /jwt_lcobucci/jwt/vendor/lcobucci/jwt/src/Signer/Ecdsa.php on line 50 and defined in /var/www/html/agi.xdua.com/jwt_lcobucci/jwt/vendor/lcobucci/jwt/src/Signer/Ecdsa/KeyParser.php:43 Stack trace: #0 /jwt_lcobucci/jwt/vendor/lcobucci/jwt/src/Signer/Ecdsa.php(50): Lcobucci\JWT\Signer\Ecdsa\KeyParser->__construct(Object(Mdanter\Ecc\Math\GmpMath)) #1 /jwt_lcobucci/test_jwt2.php(9): Lcobucci\JWT\Signer\Ecdsa->__construct() #2 {main} thrown in /jwt_lcobucci/jwt/vendor/lcobucci/jwt/src/Signer/Ecdsa/KeyParser.php on line 43

[Ocramius]

Hmm... @lcobucci do yo remember which version of mdanter/ecc was needed?

Btw, we should probably get rid of the optional dependency, even if it removes Ecdsa support.

[Spomky]

Hi @lovearthhome,

As explained in the issue to opened (see web-token/jwt-framework#122), the problem is that you are using an RSA key with an EC algorithm

"kty":"RSA" with "alg":"ES256" are incompatible.

If you want to use your RSA key, then you have to use a RSA based algorithm (RSxxx or PSxxx).
If you absolutely need to use the ES256 algorithm, then you have to use an EC key on the P-256 curve.

[lcobucci]

@Ocramius once you review #247 I can port it back to v3.3.x and then we'll get rid of it 🎉

[lcobucci]

#288 just backported PHP 7.1-7.3 support, can you please change your requirements to 3.3.x-dev and check if things are working fine for you? Important: this is still a development version and shouldn't be used in production yet.

[lcobucci]

Stable v3.3.x has already been released and we can safely close this.
