Strength	Pros and Cons
40-bit	Most browsers support it, but it’s relatively easy to break the encryption code.
56-bit	It’s thousands of times stronger than 40-bit strength and most browsers support it, but it’s still possible to break the encryption code.
128-bit	It’s over a trillion times a trillion times stronger than 40-bit strength, which makes it extremely difficult to break the encryption code, but it’s more expensive and not all browsers support it.
256-bit	It’s virtually impossible to break the encryption code, but it’s more expensive and not all browsers support it.

Description

• To use SSL in your web applications, you must first purchase a digital secure certificate from a trusted certification authority (CA). Once you obtain the certifi-cate, you send it to the people who host your website so they can install it on the server.
• A CA is a company that issues and manages security credentials. To verify infor-mation provided by the requestor of the secure certificate, a CA must check with a registration authority (RA). Once the RA verifies the requestor’s information, the CA can issue a digital secure certificate.
• Since SSL is built into all major browsers and web servers, installing a digital secure certificate enables SSL.
• SSL strength refers to the length of the generated key that is created during the encryption process. The longer the key, the more difficult to break the encryption code.
• The SSL strength that’s used depends on the strength provided by the certificate, the strength supported by the web server, and the strength supported by the browser. If a web server or browser isn’t able to support the strength provided by the certificate, a lesser strength is used.
• It’s considered a best practice to use 128-bit or better SSL strength if you process payments or collect personal information such as social security number, address, date of birth, and so on.
