uses a 256 bit Encryption certificate known as a Secure Sockets Layer or SSL

     A Secure Sockets Layer or SSL certificate is a digital certificate that authenticates the identity of a website and encrypts information sent to the server using SSL technology. Encryption is the process of scrambling data into an undecipherable format that can only be returned to a readable format with the proper decryption key.
 A certificate serves as an electronic "passport" that establishes an online entity’s credentials when doing business on the Web. When an Internet user attempts to send confidential information to a Web server, the user’s browser accesses the server’s digital certificate and establishes a secure connection.
 An SSL certificate contains the following information:
     • The certificate holder’s name
     • The certificate’s serial number and expiration date
     • A copy of the certificate holder’s public key
     • The digital signature of the certificate-issuing authority

 To verify the certificate is valid and the information you enter into the is safe just find the lock in your browser usually located to the right of your address bar and click on it or simply click the seal below.
