What is the full form of SSL?
The full form of SSL is Secure Socket Layer which is considered to be a standard security technology used for establishing the encrypted link present among the server as well as clients which are mostly the web server and that of the browser or that of the mail server and clients.
It is designed to make use of TCP to provide a consistent end-to-end secure service. Every browser might contain the capacity for interacting with that of the secure web server with the use of SSL protocol. With the use of the session keys, right after the handshaking has been done the SSL gets to use symmetric cryptography.
This mostly uses the symmetric algorithm which would be AES-128, or 256 or etc. Every browser that you check would mostly have the capability for interacting with that of the secured web server with the use of SSL protocol. It is a standard security protocol which is used to establish an encrypted link between a web server and client.
It is mainly used to provide privacy and integrity. It converts the data which is to be exchanged between two systems impossible to read. The two systems may be server and server or client and server.
A SSL certificate is required to make a secure channel between two systems which have a key pair of public and private key. It allows sensitive information like credit card numbers, social security numbers, and login credentials to be transmitted securely. It works on the transport layer.
Types of SSL Certificates
The types of SSL certificates are given below −
Wildcard SSL
Intranet SSL
Multi Domain SSL
Domain SSL
Extended SSL
Organization SSL
SSL certificates are being provided to the one who follows SSL safety measures which enables the websites which are secured such as HTTP will be changed with HTTPS, which is a more secure layer.
SSL certificates make the encryption layer which consists of the encryption key i.e public key with the identity of the website and private key is kept secret throughout the process.
A SSL certificate includes information other than just the domain name. The information included is as follows −
Domain name
Organization or device -to which the certificate was issued to
Associated sub domain
Digital signatures of the authorities
Details of the certificate authority who issued the certificate
public key
Issue date
expiration date
SSL follows the cryptographic concept of securing the data by the help of the encryption techniques used by the help of the encrypted keys which might be as follows −
Symmetric Encryption Key Cryptography
Asymmetric Encryption Key Cryptography
Secure Socket Layer Protocol Stack
The SSL protocols are as follows −
Handshake protocol
Alert Protocol
SSL record protocol
Change cipher spec protocol
| Handshake protocol | Change Cipher spec protocol | SSL record protocol | Alert Protocol |
