SSL certificate is a small data file that helps in binding cryptographic key to details of an organization. SSL certificate establishes an encrypted link in an online communication between the server and the browser. To create SSL connection, SSL certificates is mandatory.
If any web address is not secured using SSL certificate, upon transferring information (which is in readable form) through the Internet, the data can be seen and misused by anyone.
What Is Encryption Technology
Encryption is a procedure of changing over information to make it incoherent to every single unapproved party aside from the person who is a planned beneficiary. Along these lines, information integrity and data security can be kept up which has turned out to be basic for web online business. In simple words, we can state that encryption is utilized to change over information into a non-readable form and secure it from unapproved parties and is gotten by the expected beneficiary in intelligible form.
What SSL Certificate Encrypted Security Provides?
Authenticity:
This can be explained in two parts. The first part is server authentication and another is client authentication. Let’s discuss them one by one in detail.
• Server authentication: Server along with data transfers public key, which is used by the client to encrypt data used to compute the secret key. The server can decrypt data and generate a secret key only if it has a valid private key.
• Client authentication: In this, the server uses the public key, provided in client’s certificate, to decrypt data sent by the client. If the exchange of message is complete by using a secret key to encrypt, it confirms the authentication.
If in any case authentication step fails or is not complete, the session is terminated between the browser and the server.
Confidentiality:
To ensure message privacy, SSL uses a combination of symmetric and asymmetric encryption. For every session, a unique set of encryption algorithm and a shared secret key is used, ensuring the privacy of message even in case of interception.
