CFB - Cipher Feedback - Security+

Cipher Feedback (CFB) is a mode of operation for block ciphers that allows for the encryption of data in units smaller than the block size of the cipher. It turns a block cipher into a stream cipher, allowing the encryption of individual bits or bytes rather than fixed-size blocks. CFB is commonly used in cryptographic applications to provide confidentiality for streaming data. For the Security+ exam, understanding Cipher Feedback is relevant in the context of symmetric key encryption, block cipher modes of operation, and the secure transmission of data.   **🔥 Join the Geekus Maximus Elite! 🔥** If this video saved your day (or just made it brighter), smash that **Like** button and **Subscribe**!
