This question already has an answer here:
So I was reading some comments on a popular forum about SSL encryption and how some websites pass their login form data as plaintext and don't use SSL or TLS. I understand that using an encryption method allows data to pass to the server securely and stops a 3rd party from eavesdropping, and then allows decryption on the server-side.
But lets say there isn't a 3rd party sniffing the packets - is there any benefits to using SSL in that case? Or is SSL's sole purpose to encrypt packets to stop sniffers?
Thanks in advance.
