Re: Is LC encryption different for Mac than for Windows??
Thanks. I still have to test outside the network. If I have issues I will definitely check the socketTimeoutInterval. Currently it is 1. I take it that is milliseconds.

Re: Is LC encryption different for Mac than for Windows??
OIC. Well I am using the non-blocking method using with message. I don't read from until. All the data should come through then send the message. It may be that there is some kind of limit on the length of the data, but that would suck. Also it doesn't explain why when the client and the server are both running on the Mac, it works flawlessly. A socket is a socket.

Re: Is LC encryption different for Mac than for Windows??
I don't know about newer LC versions, but some older ones don't do "read from socket until EOF" correctly. Because of that, I added a data header containing the length of the data in bytes. On the receiving end, something like this happens: read from socket for 1 line put it into tLength read from socket for tLength put it into tData close socket I add error-checking of course.

Re: Is LC encryption different for Mac than for Windows??
I do. The server agent was written in LC and I am running it in a community version. Just to eliminate the possibility that things are different between Community 9.5 and Pro 9.6.8, I am DL'ing the latest (which I am running on the Mac). I'll try with that. Basically I encrypt and decrypt using aes256 and a key and salt value I store as constants in both the client and the server. I'm really stumped. This should work as advertised.

Re: Is LC encryption different for Mac than for Windows??
I was about to suggest that - you beat me to it. My client/server apps use base64 encode/decode as the final "envelope" for the data before network transfer. But I have LC on both ends of the transfer, and you may not. But ultimately it shouldn't matter.

Re: Is LC encryption different for Mac than for Windows??
Okay so I base64Encoded the encrypted string before sending over the wire, and base64Decoded on the receiving end. Same thing coming back. I am still getting the error.

Also when I was running it on my Mac, the client in the server we’re running on the same Macintosh. On the windows machine however I’m going over the wire. Should I buy Ineri encoded or something?

Re: Is LC encryption different for Mac than for Windows??
Hmmm... I think I see what is happening. I compared the encrypted string from the server to the string from the client after it received it via the socket connection. I am only getting the last part of the encrypted string! So it looks like the socket connections using with message is losing data somehow.
