What are secure websites and what are SSL certificates?

A secure connection on website makes you feel comfortable and your client will feel free in making purchases.  It is always an important component of web business to create secure atmosphere where customers feel confident in making purchases. To establish a secure connection you need to buy SSL certificate.

Secure Socket Layers (SSL) small data files combined on cryptographic key where sites information is kept. When it is installed customers feel secured in making purchases. It is an internet server it activates padlock and the https protocol which allows secure connections from web host to our browser. During transactions SSL plays an important role to safeguard credit, data transfer and log in etc. It is becoming standard while surfing on social networking sites. To make sure visitors have their connection secure, browsers offer visual cues, like being a lock icon along with a bar.

SSL certificates have 2 keys; public key and private key. For encrypted connection both keys work together. Further it has contained the information of the ‘subject’ which is the identity of the website owner. It is very simple to make your own SSL certificate and encryption keys with free software tools. These keys and certificates are more secure just like the commercial ones because they will be typically viewed more secure. Those certificates which are commercial you will need them when you require wide spread support for your own certificate. Commercial certification is built into many web browsers and operating system because of its significant commercial certification authority.

If I installed my own self-generated certification on the site when you will open the site you’d see a note letting you know that the site isn’t trusted. The most important part of SSL certification is digitally signed by a trusted CA like DigiCert. It is easy to create your own certification but customers will only feel secure while using browsers that have set of trusted CAs. Browsers have pre-installed collection of trusted CAs, known as Trusted Root CA store. You must be added to the Trusted Root CA store to become a certificate authority. A business must be protected and comply against security and authentication standards established by browsers.

A company needs to install the SSL Certificate onto its web host to begin a secure session with browsers. Once a secure connection is created, all internet traffic between your webserver and the browser will soon be secure. When you successfully installed a certification into your server, the application HTTP will change into HTTPs, in fact the ‘S’ means secure here. The type of certificate you buy and the browser that you are surfing on the internet it will show a padlock on bar which means this site has a SSL certificate installed.

Domain validation is affected with certain structural security limits. Specifically, it is always exposed to attacks which allow an adversary to observe the domain validation probes that CAs sent. A CA issues digital certificates which contain a public-key and the identity of their operator. The matching private key is not offered publicly, but kept confidential by the consumer who generated the key pair. The certificate can be an affirmation or analysis from the CA that the general public key contained in the certificate is owned by anyone, organization, server or different person noted in the certification.

CA’s duty is to verify a candidate’s credentials to make sure that user or relying parties may trust the information of CA certificate. It has variety of standards and tests to do so.

When a SSL certificate is issued by CA to an organization and its domain or website it will verify the authentication of a reputable third party. The browser now trusts the CA and because of it now trusts the organization’s identity too. When a browser makes the site secure the user may feel safe browsing the website and even input his confidential info.

Every time a browser attempts to access a website that is secure by SSL, then the browser and webserver will make a connection between them known as SSL Handshake. SSL Handshake is not visible to the consumer and occurs instantly. Basically three keys are used to make the SSL connection; public, private and session keys. Anything encrypted with the public key can only be decrypted with the private key and vice versa.

To create a symmetric session with the help of SSL handshake all encrypting and decrypting with private and public key happens and subsequently secure connection is developed. The session key can be used to encrypt all transmitted data.

There are many companies like Global Sign are known as trusted certificate authorities. Many operating systems like Microsoft, Mozilla, Opera, Blackberry and Java etc., hope that GlobalSign can be trusted. Further SSL Certificate will provide higher recognition to software, browsers and devices.
