Day 2: Stream Ciphers

What are Stream Ciphers

Stream ciphers are a type of encryption algorithm that encrypts plaintext one bit or byte at a time, rather than in large blocks. They are particularly useful in scenarios where the data comes in a continuous stream, such as in real-time communications.
