2. Types, Tools and Its Algorithms

Applications of Cryptography

Applications for cryptography as below.

Conventionally, cryptography was in implementation only for securing purposes. Wax seals, hand signatures and few other kinds of security methods were generally utilized to make sure of reliability and accuracy of the transmitter. And with the arrival of digital transmissions, security becomes more essential and then cryptography mechanisms began to outstrip its utilization for maintaining utmost secrecy. A few of the applications of cryptography are discussed below.

To Maintain Secrecy in Storage

Cryptography allows storing the encrypted data permitting users to stay back from the major hole of circumvention by hackers.

Reliability in Transmission

A conventional approach that allows reliability is to carry out a checksum of the communicated information and then communicate the corresponding checksum in an encrypted format. When both the checksum and encrypted data is received, the data is again checksummed and compared to the communicated checksum after the process of decryption. Thus, effective cryptographic mechanisms are more crucial to assure reliability in message transmission.

Authentication of Identity

Cryptography is strongly linked to the approach of using passwords, and innovative systems probably make use of strong cryptographic methods together with the physical methods of individuals and collective secrets offering highly reliable verification of identity.


The examples of cryptography include the following.

One of the prominent examples of cryptography encryption these days is end-to-end encryption in WhatsApp. This feature is included in WhatsApp through the asymmetry model or via public key methods. Here only the destined member knows about the actual message. Once after the installation of WhatsApp is finished, public keys are registered with the server and then messages are transmitted.

The next real-time application of cryptography is digital signatures. In the situation that when two clients are necessary to sign documents for a business transaction. But when two clients never come across each other they might not believe each other. Then encryption in the digital signatures ensures enhanced authentication and security.

As cyber-attacks are constantly progressing, security needs to be more necessary and thus cryptography methodologies also become more prominent. These cryptographic algorithms not only let down the hacking activities but shows no scope for these activities to emerge. Get the idea of what are the other tools and technologies available in cryptographic scenarios?
