What is Proxy SSL Encryption?
Any website that collects information from clients must consider how to keep that data safe and secure. A proxy is one way to do just that. A proxy can be set up to run on a host. SSL comes into the picture because it secures traffic or ‘data in motion’ and it’s used to secure traffic in the proxy operation. Those are the basics and a Proxy SSL Encryption setup that is run on a host is basically a dedicated computer or application that is designed to function either in between two servers or in the case of a web proxy, a server or client and the internet. If you need to secure data, an SSL proxy system is a great way to do it. You can not only protect data, you can control usage, control and improve access to resources and to data.
At the root of the system is the Secure Sockets Layer (SSL) protocol, which is an application-level encryption technology designed for the Internet. The SSL project came out of Netscape back in 1994 and was designed to answer the security needs that the coming wave of e-commerce was about to bring.
SSL comes in different levels of encryption strength, which varies by the algorithm and length of key used. When an SSL transaction takes place, private and public key pairs are exchanged, then validated which provides authentication, identity, privacy, data integrity, and confidentiality. Proxy. SSL. Encryption.
To the client, whether it’s a server or a workstation, the transaction is completely transparent. Both SSL encryption and decryption is going on between the client and the server at all times, but neither system can detect its presence, whether server or client. Some advanced Proxy SSL software can increase the security even more by implementing stronger keys and enforcing their usage throughout the transaction process.
You might be wondering how these security benefits play out in a web transaction. In a basic SSL encrypted proxy, web browsers are able to validate the identity of a web server. Everything that happens once the identity is validate happens under the secure transmission parameters of the prescribed SSL key. As far as the server is concerned, the SSL proxy acts as a client and the SSL proxy generates the shared pre-master key, it determines the keys to encrypt and decrypt. Once again, the SSL proxy at this point is acting as a server. And for the original server is authenticated by the SSL proxy, replacing the public key in the original server certificate with a key that it knows. The proxy generates a new certificate as it replaces the original certificate issuer with its own identity. The new certificate is then signed by a public key.
Proxies make it so that in the case that anyone was listening nearby, perhaps with the ability to read network packets going from a target system, the only thing that woudl be visible is nothing but static. Absolutely everything is encrypted, including which target sites and connections are being requested. Proxies go beyond SSL on their own even because in SSL, traffic headers are still visible. Combine proxy and SSL and you have a powerful combination.
Web hosts may offer Secure Sockets Layer (SSL) certificates to help you protect the personal information of your clients. For example, if you ask your clients to supply personal data to sign up for special offers on your website, the form should be secure to guard against theft, alteration, or page spoofing. This is why some software will ask if you’d like to continue sending information via Web form through a non-secure website.
Single SSL proxies prevent the need for SSL certificates from each host, but that usually requires every host behind the proxy to have the same Domain Name Server (DNS) or Internet Protocol (IP) address.
When it comes to Web hosting, many hosting providers offer simple installation of shared or private SSL certificates. Typically, adding one to your plan will incur an additional fee. The certificate will carry an expiration date, at which time you must purchase and install a new certificate.
Some hosts will even handle the installation for you. If your site collects personal or payment data from clients, protecting their sensitive information with SSL is a smart investment.
Here's What Your Proxy SSL Encryption Hosting Needs To Offer
If you need to use SSL certificates for security reasons, but are in a situation where sharing server keys isn’t possible, a SSL proxy can help. Setting up an SSL proxy is an advanced hosting arrangement, and you’ll want to select a host with specific expertise to manage this type of authentication arrangement. We found HostPapa to be a good options for SSL proxy hosting.
