Jan 2, 2025 · Data encryption is the process of converting readable information (plaintext) into an unreadable format (ciphertext) to protect it from unauthorized access.

Apr 22, 2025 · Data Encryption Standard (DES) is a symmetric block cipher. By ‘symmetric’, we mean that the size of input text and output text (ciphertext) is same (64-bits). The ‘block’ here means that it takes group of bits together as input instead of encrypting the text bit by bit.

What is a Data Flow Diagram? A data flow diagram illustrates how data flows throughout the system. It answers the questions: How does data enter the system? How and where does data travel within the system? How does data exit the system? How is data changed or transformed throughout the system? Where is data stored?
