256-Bit Encryption

Encryption is the process of changing data into a form that can be read only by the intended receiver. 256 Bit SSL is referred to as strong SSL security. The 256 Bit Encryption tells users that the size of the encryption key used to encrypt the data being passed between a Web browser and Web server is 256 Bits in size. Because the size of the 256 Bit key is large it is computationally unfeasible to crack and hence is known as strong SSL security.

Browser Compatibility

Web.com UK SSL Certificates are compatible with over 99% of Web browsers which means that most existing browsers recognize a given Certificate and thus secure transactions can take place on those browsers. This ensures that your nsProtect™ Secure SSL Certificate will work on most browsers being used to view your site.

Certification Authority

Certification Authorities (CA) are third-party verifiers that authorize and endorse the legitimacy of websites. Browsers inherently trust an SSL Certificate if it is current and is issued by a reputable CA since trusted CAs will only issue Certificates to websites after validating the legitimacy of that site.

Data Encryption

Encryption is the process of changing data into a form that can be read only by the intended receiver. To decipher the message, the receiver of the encrypted data must have the proper decryption key. In traditional encryption schemes, the sender and the receiver use the same key to encrypt and decrypt data. Public-key encryption schemes use two keys: a public key, which anyone may use, and a corresponding private key, which is possessed only by the person who created it. With this method, anyone may send a message encrypted with the owner's public key, but only the owner has the private key necessary to decrypt it. The 256 Bit tells users that the size of the encryption key used to encrypt the data being passed between a Web browser and Web server is 256 Bits in size. Because the size of the 256 Bit key is large it is computationally unfeasible to crack and hence is known as strong SSL security.

Domain Validation (DV) Certificates

DV Certificates are issued only after verifying/ confirming the registrant or person who registered the domain name originally. This is done by using currently established and accepted vetting process, such as an email based communication to confirm the information. Essential SSL Certificates are validated and issued within minutes after completion of verification process and base on system availability. See Issuance Time for more information.

Extended Validation (EV) Certificates

EV Certificates provide a higher level of validation and are available to all business and government entities, but are not available to individuals. The EV process is more rigorous and detailed than for any other Certificate and will require additional steps, which may include obtaining signatures from several people within the applying company, legal verification of the business's existence, etc. EV Certificates provide additional visual assurance by turning your browser address bar green (when using modern browsers like IE7).
