Free SSL
Insiders: We’ll get basic idea about SSL and cover all possible free SSL certificates providers that will help you to choose the better provider that is perfect for your needs validation through pros and cons.
SSL (Secure Socket Layers) is basically a protocol which establishes encrypted link between web server and browser. It ensures secure web browsing via HTTPS protocol. A public HTTPS website contains SSL certificate signed by publically trusted certified authority. SSL works on the principle of cryptology where identities of websites and companies are bound by key pairs via digital X.509 certificates. Each pair consists of private and public key where private key is kept secured and public key is distributed via a certificate. Public key encrypts the message into cypher text which is send to receiver. And now the receiver decrypts it using private key. The holder of the private key can use it to sign other digital documents (such as web pages), and anyone with the public key can verify this signature. In this manner complete communication remains private and data is secured from theft and hacking.
All SSL certified websites’ address starts with “https://” and non-secured websites’ address starts with “http://”. We then can easily identify whether our channel is SSL secured or not. According to recent reports Google will wave off and remove all the non-secured websites which involve credit card or debit card or any sort of confidential transactions or form filling to prevent the stakeholders from attacks of intermediates or hackers. Hence whenever you enter into secure SSL certified website, you are assured of
- Authenticity
The server presenting the certificate is in possession of the private key that matches the public key in the certificate.
- Integrity
Documents signed by the certificate (e.g. web pages) have not been altered in transit by a man in the middle.
- Encryption
Communications between the client and server are encrypted.
By now you must have understood the importance of SSL certificate. If you are thinking to have a website of your own then you must generate a pair of public and private keys, preferably on the server to be protected. The public key, along with the domain name(s) to be protected and (for OV and EV certificates) organizational information about your company is used to generate a certificate signing request (CSR). The CSR is sent to a publicly trusted CA (such as SSL.com). The CA will validate the information in the CSR and generate a signed certificate that can be installed on your web server.
The cost of SSL certificate varies. There are some domains who offer free or low cost certificate but the duration of that certificate is short and needs to be updated as when required. More the duration, more is the cost. We’ll now talk about forums where you can get free SSL of your choice to get started.
