About this video
Day 25 of my 100-Day Cybersecurity Challenge π
π₯ Public Key Cryptography Basics (Hinglish)! π
Aaj hum samjhenge β RSA ka simple numeric example, Diffie-Hellman key exchange step-by-step, SSH server/client auth, digital signatures & certificates, aur PGP/GPG ka practical use. Ye video beginners ke liye simple hai aur real CTF/pentest scenarios ke liye useful hai.
π What youβll learn (quick):
β’ Why asymmetric keys exist vs symmetric keys
β’ RSA β step-by-step numeric example (use these exact numbers)
β’ Diffie-Hellman β simple walkthrough with p=29, g=3, a=13, b=15 (calculate shared secret)
β’ SSH host authentication & key auth (how ssh-keygen works)
β’ Digital signatures & certificates β what they actually prove
β’ PGP / GPG β generate key, share public key, decrypt example
