  <p>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...</p>
  
  <pre><code>      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;
  
     }
