Cryptography
Cryptography is defined as the art or science of secret writing with the use of techniques such as encryption. Encryption is the process of converting data into unreadable code so it cannot be accessed or read by unauthorized people. This unreadable data can again be converted into a readable form by the process of decryption. Different types of algorithms are available for encryption and decryption.
Symmetric Encryption vis-à-vis Asymmetric Encryption
Encryption can be of two types, that is, symmetric encryption and asymmetric encryption. The following table will help you understand the differences between the two:
Symmetric Encryption |
Asymmetric Encryption |
A single key is used to encrypt and decrypt messages |
Two keys are used: one for encryption and another for decryption. |
It is known as symmetric... |
