Mathematical analysis of data was a well-established process in science when Kepler began studying Tycho's data.

Cryptography is basically the process of hiding information in order to protect the sensitive information, data or message from unknown attacks for any reasons. Cryptography actually consists of two terms encryption and decryption. The process in which message is ciphered or encrypted is known as encryption and the process in which message is deciphered at recipients end is known as decryption. And this whole process is known as cryptography. Public keys and private keys are used in the process of cryptography. Cryptography can be seen as symmetric and asymmetric. In symmetric cryptography same key is used for both encryption and decryption while in asymmetric different keys are used for both encryption and decryption. Today Cryptography is used in various fields like ATM, e-banking, IT security, Maths etc.
Theory.
data means good grasoius what does it mean.
There are two general types of modern cryptography; symmetric cryptography and asymetric (also known as public key) cryptography. Symetric crypto is where both sides have the same shared encryption key, and that key is used to both encrypt and also decrypt any encrypted information. Symmetric crypto is more efficient (faster) than asymmetric crypto, but asymetric crypto works without having to share a key.
How data encrypt and decrypt from PC to PC using micro controller?
main diff is cryptography in change the code format of original data & image stenography hide the data behind other file not change the data code this is main diff b/w image stenography & cryptography.
to provide the security for data

To encrypt data
From my recolection you cannot encrypt a single worksheet. You can password the sheet, and you can hide the data There is a small programme that's does encrypt called NCrypt XL
For privacy and security. The data is personal and private.

SSH and HTTPS
Someone can encrypt their email address through a number of methods such as using encoders that are available on the net that encrypt and hide the email address of individuals. Another method would be to encrypt the data packet so that no one can see it except the recipient.
