Data security is not full-filled without knowing cryptography concept, even if u can see in social networking software like whats app,viber you can see end to end encryption are all falls in cryptography only.
Now let us look what is cryptography, its a secret writing. Its a type of secure communication whose meaning is kept secret, crypto-analysis is the process of breaking secure communication and reading the secret message.
Below are the some of the definition,which we are going to use in cryptographic technique. Plain text is the term refer to readable message before applying cryptographic algorithm. chipper is the encrypted message after applying Cryptographic algorithm.
Encryption steps in cryptography :
- Plain text –> Encryption Key–> chipper text
Decryption Steps in cryptography :
- Chipper text –> Decryption key –> Plain text
A good encryption will contain a strong cryptographic, which cannot be easily break it, crypto graphic concept is not a new technology, its has be rooted back to old ages its concept is used during medieval period also. but the technology and algorithm is changed over period of time
It has been differentiated into two categories
- Classical Cryptography
- Computer era cryptography
We will look on deep into above two cryptography on upcoming posts
