can I transfer some data securely... for example.. I retrieve some data from Systm A database... and send those data to System B to process something using that data. ( the System B cannot connect to System A database)
So in between, what are the best ways to send data securely... ?
I did one experiment with get database data to an array and encode to json and then again encrypt with md5 and post/get data to other system. Sometimes it takes little time to post when large amount of data to process. So I'm not sure that's the correct way to do... Any suggestions would be helpful... Thanks
VPN, ssh
Use Rsync with key authentication to the server it would be secure enough, you may need vpn in a highly extremely secure environment, there are good php wrappers for rsync if you like
