Encryption and decryption are the heart of the SSL security algorithm in which information traverse between browser and server is converted into complex text which is called encryption & the receiver side, the complex text again converted into original information which is called decryption.
This was the simple explanation of the terminology. Let’s dig deeper to understand the technical explanation of this complex process.
Encryption is a ciphertext that is hard to decode and the data sender and receiver can only encrypt the information. To recover the content of an encrypted text, there should have a correct algorithm key.
The more compound the encryption algorithm, the harder it turns to eavesdrop on the communications.
Encryption can be applied to keep the intruder away from getting the content of the transmitted data. Complex ciphers or encryption works in line with sophisticated computer algorithms that arrange data bits in digital signals.
To decrypt the encryption, a data receiver needs decryption key. Encryption keys are of two types: Symmetric encryption and Public key encryption.
Symmetric encryption carries the same two keys being used for communication while in public key encryption; the key is distributed publicly for anyone to encrypt the message. Only the receiver has the access to the decryption key.
Encryption is used in securing data transition done through networks, wireless microphones, mobile, wireless intercom, Bluetooth device, automatic teller machine.
Encryption is extremely important where data like credit card or debit card information is transferred between the user’s browser and the website server. To make your data stronger and encrypted, a person or organization has to take a legitimate SSL certificate from a reputed certificate authority.
