convert string to private and public key (RSA)

Question

The two strings that are the private and public keys are :

    static String Public =          
       "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDH+wPrKYG1KVlzQUVtBghR8n9d" + "/n" +
     "zcShSZo0+3KgyVdOea7Ei7vQ1U4wRn1zlI5rSqHDzFitblmqnB2anzVvdQxLQ3Uq" + "/n" +
    "EBKBfMihnLgCSW8Xf7MCH+DSGHNvBg2xSNhcfEmnbLPLnbuz4ySn1UB0lH2eqxy5" + "/n"+
     "0zstxhTY0binD9Y+rwIDAQAB"+ "/n";
    static String Private = 
        "MIICxjBABgkqhkiG9w0BBQ0wMzAbBgkqhkiG9w0BBQwwDgQIr5NQ/LYPG/UCAggA" +"/n"+
      "MBQGCCqGSIb3DQMHBAiLh89iGSkmoASCAoBCpAo9/IzDE3yGhvWr9RgozE7revOo" +"/n"+
          "V2OXmU+d0+WYAAx2GYVaUCbFVrmgiVmrbiTgLUMXAGIpvxQ2rzyIvRHW/RN3Gcky" +"/n"+
        "qR/AwBatzixqrnoS4aD1/Ovjr4hwde4XHYbPEilZZuVAJFiznhy73qm/So4XghSY........." ;

I have read the other questions and tried their solutions but nothing worked....I have a public and private key both as strings.. I need to convert them to 'Key' but i keep getting java.security.spec.InvalidKeySpecException: java.security.InvalidKeyException ..at generatePublic and generatePrivate functions.. also the keys are just for testing therefore, it is ok if they are known to others...

      public static Key loadPublicKey(String stored) throws GeneralSecurityException, IOException 
       {
      byte[] data = Base64.getDecoder().decode((stored.getBytes()));
      X509EncodedKeySpec spec = new X509EncodedKeySpec(data);
      KeyFactory fact = KeyFactory.getInstance("RSA");
      return fact.generatePublic(spec);

        }


public static Key loadPrivateKey(String key64) throws     GeneralSecurityException, IOException {
        byte[] clear = Base64.getDecoder().decode(key64.getBytes());
        PKCS8EncodedKeySpec keySpec = new PKCS8EncodedKeySpec(clear);
        KeyFactory fact = KeyFactory.getInstance("RSA");
        PrivateKey priv = fact.generatePrivate(keySpec);
        Arrays.fill(clear, (byte) 0);
        return priv;

   }

Answer 1

Remove the line Feeds in the string declaration. That is not part of the key:

static String Public =          
       "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDH+wPrKYG1KVlzQUVtBghR8n9d" +
     "zcShSZo0+3KgyVdOea7Ei7vQ1U4wRn1zlI5rSqHDzFitblmqnB2anzVvdQxLQ3Uq" + 
    "EBKBfMihnLgCSW8Xf7MCH+DSGHNvBg2xSNhcfEmnbLPLnbuz4ySn1UB0lH2eqxy5" +
     "0zstxhTY0binD9Y+rwIDAQAB";
static String Private = 
        "MIICxjBABgkqhkiG9w0BBQ0wMzAbBgkqhkiG9w0BBQwwDgQIr5NQ/LYPG/UCAggA" +
      "MBQGCCqGSIb3DQMHBAiLh89iGSkmoASCAoBCpAo9/IzDE3yGhvWr9RgozE7revOo" +
          "V2OXmU+d0+WYAAx2GYVaUCbFVrmgiVmrbiTgLUMXAGIpvxQ2rzyIvRHW/RN3Gcky" +
        "qR/AwBatzixqrnoS4aD1/Ovjr4hwde4XHYbPEilZZuVAJFiznhy73qm/So4XghSY........." ;

I have tried it with the following code:

  public static void main(String[] args) throws GeneralSecurityException, IOException {
      System.out.println(loadPublicKey(Public));

  }

  public static Key loadPublicKey(String stored) throws GeneralSecurityException, IOException 
  {
 byte[] data = Base64.getDecoder().decode((stored.getBytes()));
 X509EncodedKeySpec spec = new X509EncodedKeySpec(data);
 KeyFactory fact = KeyFactory.getInstance("RSA");
 return fact.generatePublic(spec);

   }

And Output is:
