Key Cryptographic Concepts

This course explores the core principles of cryptography, focusing on two main types of systems:

• Symmetric Key Cryptosystems: Utilize a single secret key for both encryption and decryption.
• Asymmetric Key Cryptosystems: Employ a pair of keys – a public key for encryption and a private key for decryption. This offers enhanced security and key management.

Encryption is the process of transforming readable data (plaintext) into an unreadable format (ciphertext). Decryption reverses this process, converting ciphertext back into plaintext. Encryption typically occurs at the sender's end, while decryption happens at the receiver's end.
