What is Encryption and How Does It Work?

Encryption is the process of converting data into a code to prevent unauthorized access. It involves using an algorithm to scramble the data and a key to decrypt it back into its original form. This ensures that only authorized parties can access and understand the information being transmitted.

Encryption works by taking plaintext data and running it through an encryption algorithm along with a key, producing ciphertext. The ciphertext can only be decrypted back into the original plaintext by using the same algorithm and key. This process helps protect sensitive data such as personal information, financial details, and communication from being intercepted or tampered with by malicious actors.

Overall, encryption is a crucial component of cybersecurity and data protection, ensuring the confidentiality and integrity of information in various online transactions and communications.
