Load RSA Keys from Modulus and Exponent in Java

See below.

// Hardcode the RSA key
String modulusString = "00d56047acf652298e3fcdbb8cecbc32214722aa1625f88480cf570cee373ada932b140c29b00dc44f6e59e7018dddca66b2f1c645dacb9d4a45459cfa8f7e33df";
String exponentString = "18bc01730656bde47476f7cfbd3d8f9e15ede9c389814672dc161e349b08627fc885fe9d2442ae92f0214c7e97cf0b9a9fc876df4f53517ab63d710f997b2779";
String publicExponentString = "65537";
		
// Load the key into BigIntegers
BigInteger modulus = new BigInteger(modulusString, 16);
BigInteger exponent = new BigInteger(exponentString, 16);
BigInteger pubExponent = new BigInteger(publicExponentString);
		
// Create private and public key specs
RSAPrivateKeySpec privateSpec = new RSAPrivateKeySpec(modulus, exponent);
RSAPublicKeySpec publicSpec = new RSAPublicKeySpec(modulus, pubExponent);
		
// Create a key factory
KeyFactory factory = KeyFactory.getInstance("RSA");
		
// Create the RSA private and public keys
PrivateKey priv = factory.generatePrivate(privateSpec);
PublicKey pub = factory.generatePublic(publicSpec);
