How can you hide by the help of cryptography

How can you bear when you are sending a confidential quote or any secret email to your client without encryption?

It is really irritating when you are trying to hide certain things and other people easily notice those. It is too risky when you are making any transaction on internet and you don't have any security.

Thanks to modern development, we have the facility of cryptography.

• Through cryptography, internet can easily be navigated with the help of extra security.

• Threats of securities are increasing day by day with the expansion of internet. So here we have the art of transforming the text by cryptography in to different incomprehensible forms, it can be with proper algorithm (encryption) or if we go against it then is (decryption)

• During Julius Caesar's reign, cryptography had its own value, to communicate with his generals, Caesar use ciphered messages. It is a very simple process, you just have to replace a text with another variable or you can add authentication or any digital signature.

• This process requires the key system used in encryption and decryption.

• In the past, cryptographic equations which were older could easily be broken.

• With the discovery of frequency analysis, scientists are able to develop stronger cryptography.

• Running symmetric key can be algorithmic stream cipher

• Block cipher can be another form of running symmetric key.

• Encrypting the bits of information stream cipher is done.

• Block cipher can be done by encrypting the blocked information.

In modern days, asymmetric key cryptography is going at faster pace which includes both a private and public key. As compare to symmetric key algorithm, there are many new things; the main notion in the modern one is that public key is available to every one. Here private key for decryption remain in secret.
