Was this code written by you, Alloy Bacon?

[AS3.0]

Yes. Its free. And I wouldnt be able to do it without the developer guides because thats like knowing your way through someones house without asking them. I didnt invent ftp i just released a simpler version for myself to use on this NAS device I have so multiple as3 servers on various local computers can read and write files to store as a database. Its like 1 server goes down and the other one still has all the same data for the clients connecting.

For sftp which is a whole different modern secure version I have as3 libraries like Blowfish symmetric-key block cipher to handle the data but only thing I stopped writing it because I cant tell where the first 14 bytes are coming from when recording the data with a tcp packet capture, sftp is good to communicate with modern webservers sftp like lamp to transfer from as3 to lamp etc. I dont think i will finish sftp because its for the NAS which is modern device that still uses plain ftp

I have written an as3 ftp like above that can do more like handle a queue of multiple files you need made with unique data per file. I tested it to create 50k different files and they were all in the queue and eventually made pretty fast. ill sell the ftp version thats multithreaded for like $5 paypal if someone wants

[AS3.0]

$5 for my multithreaded as3 ftp read/write script and ill buy something off you later on of around the same value that you made and want to sell.
