Encryption is the process of encoding data in such a way that only authorized parties can access and understand it. It transforms plaintext data into ciphertext using cryptographic algorithms and keys.
In the context of securing network traffic, encryption is essential to protect sensitive information from unauthorized access. By encrypting data before transmitting it over a network, even if intercepted, it remains unreadable to unauthorized users. Only those with the appropriate decryption key can access and decipher the data.
