Encrypted Data over Sockets

[Alex Tweedly]

But, an encoded array is STILL binary data. So any issues with "read 
until linefeed" will still exist.

Try sending a header with number of bytes, followed by the bytes.

If you really wanted, you could do:

    write  (the number of bytes in tSocketData) & linefeed to socket tSocket
    write tSocketData & linefeed to socket tSocket

and then when you read,

    read from socket tSocket until linefeed
    put it into tNumBytes
    read from socket tSocket until linefeed
    put it into tData

and compare tNumbytes with the number of bytes in tData

Or, just do

    read tnumbytes form socket tSocket

They is just something wrong with the data. Curiously, if I just send and receive plain text it works every time.
