Hi there,
I'm writing the code for a pool but I am sure that some informations need to transfer in a secure connection with the server. Most pools use an SSL certificate to make the connection secure: how much could it cost? Initially I thought that I could use javacript to encrypt with sha2 the password field in the form before sending it to the server, but there are other informations that I can't send in encrypted form, as the bitcoin address of every user. So I found this but I am not very convinced about that. There other ways? Which is the best?

Thanks,
turlando.
