Encryption is a security process to convert data into an unreadable code. The purpose is to ensure that sensitive data is protected from unauthorized access. Encryption happens when data is being transmitted or stored to keep it secure. The process uses complex mathematical algorithms, to convert readable data (plaintext) into unreadable data (ciphertext). Only those with the decryption key is able to reverse the encryption process to access the original data. Encryption is widely used in online transactions, communication, and data storage, to protect against unauthorized access and cyber threats.

Decryption is the reverse process. It converts encrypted data back to its readable form (plaintext) using the correct decryption key. Decryption takes place when the intended recipient receives the encrypted data and uses the proper key to restore the original message.

These two processes work together to safeguard data from unauthorized access and tampering.
