Here in this blog i am explaining the basic Key points of cryptography.
Cryptography
Cryptography is an art of protecting the information by transforming it into a codable format.it is a word taken from Greek language which means Hidden Secret.it is also said to be a way of secret Writting.we can secure our information through Crytography.

Types of Cryptography

Public key Crytography:- public key cryptography uses two keys as one key for Encrytion and another key for Decryption.
Secret Key Cryptography:- Secret key Crytography uses a single key for both Encryption and Decryption.

PlainText
PlainText is a simple Text Entered by the user.which is in a simple language form.
CipherText
cipherText is a Message which is in a Encrypted form.and a person having Secret key only change it into a Language form.
HashFunction
HashFunction uses a mathmatical Transformation irreversibly to Encrypt Information.
Encryption
encryption is a process for converting the plainText into cipherText.
Decryption
Decryption is a process for back conversion from CipherText to plainText.
