Encryption is a critical cybersecurity technology used to protect sensitive data during transmission and storage by converting it into an unreadable format, which can only be decoded with a decryption key. It ensures confidentiality, integrity, and security for data in transit (such as over networks) and at rest (such as stored in databases). Below is an overview of key encryption documents and concepts:

1. Encryption Overview and Purpose

• Definition of Encryption: Encryption involves converting plaintext (readable data) into ciphertext (unreadable data) using an algorithm and a key. This ensures that even if data is intercepted or accessed by unauthorized parties, it cannot be understood or used.​

2. Types of Encryption

• Symmetric Encryption:

  • Description: In symmetric encryption, the same key is used for both encryption and decryption. It is faster than asymmetric encryption but requires secure key management.

3. Encryption Algorithms

• AES (Advanced Encryption Standard): One of the most widely used symmetric encryption algorithms, which encrypts data in fixed-size blocks (128-bit blocks) with key lengths of 128, 192, or 256 bits.​

• Document Required: ECC implementation standards, key size recommendations, and usage guidelines for secure communication.

4. Encryption Key Management

• Key Generation and Exchange: This document covers the process of securely generating encryption keys and sharing them between communicating parties.​
