Facebook is now rolling out encryption technology to all users.

"As announced last year, we are moving to HTTPS for all users," Facebook's Shireesh Asthana wrote in a blog post. "This week, we're starting to roll out HTTPS for all North America users and will be soon rolling out to the rest of the world."

HTTPS keeps data encrypted as it travels between your Web browser and servers and is mostly used for things like banks and credit card company Web sites.

Initially, Facebook used HTTPS whenever your password was sent to the social-networking site. In an effort "to keep your data even more secure," Facebook that it would provide the option to encrypt an account at all times. At the time, the company said it hoped "to offer HTTPS as a default whenever you are using Facebook sometime in the future."

Facebook gave app developers until Oct. 1, 2011 to support HTTPS. "We feel that HTTPS is an essential option to protect the security of Facebook accounts, and since Apps on Facebook are an important part of the site, support for HTTPS in your app is critical to ensure user security," Facebook said last year.

A similar option is available for , , and .

As Facebook noted last year, enabling HTTPS might make the social network a tad sluggish. "Encrypted pages take longer to load, so you may notice that Facebook is slower using HTTPS," Facebook said.
