In the Name field, enter a name that you can remember. It will default to the name of the Web site for which you're generating the CSR. When you generate the CSR, you need to specify a bit length. The bit length of the encryption key determines the strength of the encrypted certificate which you send to the third-party CA. The higher the bit length, the stronger the encryption.
Most third-party CAs prefer a minimum of bits. In the Organization Information section, enter your organization and organizational unit information. This must be accurate, because you are presenting these credentials to a third-party CA and you must comply with their licensing of the certificate.
For SSL certificates, enter the host computer name with the domain name. Select Next to access geographical information. Enter your country, state or province, and country or region information. Completely spell out your state or province and country or region; don't use abbreviations.
Confirm your request details. There are different methods of submitting your request. Contact the certificate provider of your choice for the method to use and to determine the best certificate level for your needs.
Depending on the method that is chosen for sending your request to the CA, you may send the CSR file from step 10 in the Generate the CSR section, or you may have to paste the contents of this file into the request. This file will be encrypted and will contain a header and a footer for the contents. You must include both the header and the footer when you request the certificate. Your CSR should resemble the following:. Once the third-party CA has completed your request for a server certificate, you will receive it by email or download site.
The certificate must be installed on the Web site on which you want to provide secure communications.
Now that the server certificate is installed, you can enforce SSL secure channel communications with clients of the Web server. First, you need to enable port for secure communications with the Web site. To do this, follow these steps:. In regular communication over a network, a client contacts a server with a request. The server replies with a response. Under SSL, only the client needed to present authentication.
With TLS, both the client and server must prove their identity. The identification procedure includes an encryption key, which is used to protect all transmissions once the connection has been established.
The SSL system relies on the user holding a valid certificate. The certificate validates the client or the server by showing their address, a validity period and a digital signature.
Certificates are issued by Certificate Authorities. When a client first contacts the server, it presents its certificate. The server sends its certificate details to the client and checks the clients certificate with the issuing authority.
Encryption Process of transforming readable plaintext data into an unintelligible form ciphertext so that the original data either cannot be recovered one-way encryption or cannot be recovered without using an inverse decryption process two-way encryption.
Extended Validation EV SSL Certificates The most comprehensive form of secure certificate which validates domain, require very strict authentication of the company and highlights it in the address bar. Key exchange This is the way users and server securely establish a pre-master secret for a session. Master secret The key material used for generation of encryption keys, MAC secrets and initialization vectors. Pre-master secret The key material used for the master secret derivation.
Public key infrastructure PKI Architecture, organization, techniques, practices, and procedures that collectively support the implementation and operation of a certificate-based public key cryptographic system.
The PKI consists of systems that collaborate to provide and implement the public key cryptographic system, and possibly other related services. When a secure server is in use, the server is authenticated to the user.
In addition, user information is encrypted by the user's web browser's SSL protocol before being sent across the Internet. Information can only be decrypted by the host site that requested it.
SSL Stands for secure sockets layer. Protocol for web browsers and servers that allows for the authentication, encryption and decryption of data sent over the Internet.
SSL certificate Server certificate that enables authentication of the server to the user, as well as enabling encryption of data transferred between the server and the user. Symmetric encryption Encryption method that imply the same key is used both during the encryption and decryption processes. Wildcard SSL certificates Type of certificate used to secure multiple subdomains. Security Topics. We have updated our Privacy Policy which can be found here.

Levels of business authentication As well as encryption, Certificate Authorities CAs can also authenticate the identity of the owner of a website, adding another layer of security. Organization Validation SSL Certificates This requires the applicant to not only prove they own the domain name they wish secure, but also prove that their company is registered and legally accountable as a business.
Compare SSL Certificates. How does an SSL certificate work? The user then checks the validity of the certificate, and selects the highest level of encryption that can be supported by both parties and starts a secure session using these methods. There are a good number of sets of methods available with various strengths - they are called cipher suites. To guarantee the integrity and authenticity of all messages transferred, SSL and TLS protocols also include an authentication process using message authentication codes MAC.
All of this sounds lengthy and complicated but in reality it's achieved almost instantaneously. Offering memberships If sites offer membership or anything that involves collecting email addresses and other sensitive information, then SSL is a good idea. If forms are used The same applies if they use any kind of form where users will be submitting information, documents, or images.
Does SSL work across all devices? Devices and operating systems Again all of the big operating systems for computers, tablets and mobile phones are supported. Browser compatibility People use a range of different browsers Chrome, Firefox, Safari etc to access web content.
Servers Thanks to the way SSL works, servers don't really need to have root certificates embedded but you will need to install the corresponding intermediate certificate s. What are the visual implications of SSL?
How to implement an SSL certificate on a site Depending on how a site is hosted and where, there are various ways of adding an SSL certificate. Click Here for full installation instructions. SSL Summary SSL is an important security tool for business and one that is playing an increasing role in the success of online transactions.
