Speaking on general terms,

Conversion of plain text into cipher text using an algorithm and a key is called as Encryption and Conversion of cipher text back to plain text using algorithm and key is called as Decryption.

Encryption assures the information is accessed by the authorized users only.

There are two main types of encryption

1. Symmetric Encryption/ Public-key encryption

2. Asymmetric Encryption/ Private-key encryption

Symmetric Encryption uses same key for the encryption and decryption.

Asymmetric Encryption uses different keys for encryption and decryption.
