java - Socket Programming - CipherStream -

-

I am doing file transfer (socket-java) programs where I am sending an encrypted version of the file to the customer. The customer will decrypt it and store it in its drive.

I am using the CipherOutputStream ANF cipher inputstream for encryption and decryption. When my problem is encrypted, I have to close seeperoptrast and the file is not getting to the client. I need to get the receipt from the customer after sending the file, because I am closing the cipher output stream in the server, this message from the client Is not receiving Its throwing socket closure exception.

Is there another way to send a file in an encrypted format to the client so that the client will decrypt it and store it in its repository.

Please require some advice.

Once the stream is closed, you can not send

as My comment has been written, You can send the length of the file first to the customer, so that the customer will know how much byte he has to read. Once the client reads this amount of data, then the client can send them back because the stream is not closed. After the server receives a receipt, it can close the stream or start another transfer.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
