RC4 Stream Cipher Explained in Hindi | KSA & PRGA with Example

In this video, we explain the RC4 Algorithm in Hindi with a complete step-by-step example. RC4 (Rivest Cipher 4) is a stream cipher used earlier in SSL/TLS, WEP, WPA, and file encryption. We cover the complete working of RC4 including: - Stream Cipher vs Block Cipher recap - RC4 Algorithm overview - Key Scheduling Algorithm (KSA) - Pseudo-Random Generation Algorithm (PRGA) - RC4 Encryption and Decryption with example - Why RC4 is insecure today This video is very useful for: - Computer Science students - Cryptography beginners - Cyber Security learners - Exam & interview preparation 📌 Topics Covered: ✔ Stream Cipher ✔ Block Cipher ✔ RC4 Algorithm ✔ KSA and PRGA ✔ RC4 Example ✔ RC4 Weaknesses 👍 Like | 🔔 Subscribe | 🔁 Share Comment below if you want the next video on AES, DES, or ChaCha20. #RC4 #Cryptography #StreamCipher #CyberSecurity #ComputerScience
