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.

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. It's not a problem with sending data over the wire.

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.

Is LC encryption different for Mac than for Windows??
Hi all. As I may have mentioned I wrote an SQL Server agent that uses sockets to listen for data from a client. The client first arrayEncodes an array, then encrypts the result using an encryption library I wrote. Then it sends the data to the Server Agent. The Agent receives the encrypted stream, decrypts it using the exact same library, arrayDecodes the data, then performs a query against the database and retrieves th data as an array. All that works. The agent then arrayEncodes the array and re-encrypts it using THE SAME LIBRARY. It then sends the data back to the client which of course, decrypts it and arrayDecodes it producing the resultant array. All fine and good. But wait there's more! When I run the Server Agent on my Macintosh all works as expected. I get an array of the queried data. When I run it on a Windows desktop however, the data coming back is corrupted somehow! The decryption command produces an error: ERROR: (SSL error: wrong final block length) How can that be? It's the same file I just copy it to the windows machine from the Mac along with the encryption library. Everything should be exactly the same!
