What is Encryption and Decryption? Explained in Urdu/Hindi

what is encryption and decryption? explained in Urdu/Hindi ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~- In this video, I will tell about Encryption and Decryption: Encryption is the process of encoding message and data in such a way that only authorized parties access it and who those are not authorized cannot access it. simply we can say that we encode our messages or data or information with the help of an algorithm. Decryption is the process of transforming encrypted information so that it is intelligible again. or simply we can say that the process of decoding an encoded data and make its original form by using the algorithm is called decryption. so, the question is arise why we use encryption simply with the help of encrypting data we create a security layer in our data or messages to avoid hackers and intruders. there are many encrypting algorithm you don't need to follow them you also make your own but there are some popular algorithms are as follows: SHA-256 (use in crypto currency to make it secure) IPsec (use by the vpn servers) and there are two types of encryption are as follows: Symmetric-key Asymmetric-key Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext. Asymmetric cryptography, also known as public key cryptography, uses public and private keys to encrypt and decrypt data. and these public and private key both are not same without private key you will not decode any encrypted message. ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~- LINKS SECTION: ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~- What is VPN? link: https://goo.gl/djeoLV ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~- Fb page link: https://goo.gl/qYTku4 ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~- I hope you enjoyed this video if you think this video is best so please give it a thumbs up and if you have any query related to my channel so put in the comment section below and share it with your friends for increasing their knowledge. -~-~~-~~~-~~-~- Please watch: "How To Get TCS Jobs In Pakistan [2019] || TCS Job Programme" https://www.youtube.com/watch?v=IrwQqGrU0JE -~-~~-~~~-~~-~-
