Version 6.1.4

RSA Keys without primes can be used as any other keys. Primes are computed by the library.

Such keys SHOULD NOT be used as pure PHP computation are performed before the key is used.

We highly recomment you to pre-compute primes and save the new key:

use Jose\KeyConverter\RSAKey;
use Jose\Factory\JWKFactory;

$values = [
    'kty' => 'RSA',
    'n' => 'gVf-iyhwLn2J2Up4EKjwdLYmk5n24gjGk4oQkCHVcE7j8wkS1iSzcu0ApVcMPLklEp_PWycZE12vL90gPeVjF2IPL_MKFL0b6Wy7A1f4kCDkKv7TDDjt1IIwbS-Jdp-2pG7bPb3tWjJUu6QZBLoXfRtW3cMDkQjXaVGixENORLAZs6qdu2MMKV94jetCiFd0JYCjxGVC0HW2OKnM21B_2R1NubOvMlWA7gypdpvmBYDGpkw4mjV3walWlCZObG7IH84Ovl7wOP8XLzqi2un4e6fNzy3rdp4OUSPYItF4ZX5qThWYY2R47Z5sbrZxHjNeDECKUeio0KPQNrgr6FSKSw',
