Description
Encryption is the process of scrambling data to protect personal files, secure communication, hide identities and much more.
In this video we will learn about the different type of encryptions we will talk about symmetric encryption, asymmetrical encryption, where they are used for and the pros and cons of each one.
Symmetric encryption
Asymmetrical encrypt
Pros and cons of sym va asym
Symmetric encryption
Might as well just call it classic encryption I would argue and i think this is the first encryption known to us. I have some thing I dont want anyone to see I use a lock key to lock it. Only I can open it unless I have a lock.
The same key you use to encrypt is the same key to Decrypt.
Examples
Examples of popular symmetric-key algorithms include
AES
Twofish
Serpent
DES
Twofish, Serpent, AES (Rijndael), Blowfish
CAST5, Kuznyechik, RC4, DES, 3DES, Skipjack, Safer+/++ (Bluetooth), and IDEA
Asymmetrical encryptions
We had symmetric encryptions for a long time, then internet came and networking and we needed to encrypt messages going back and forth. We said cool lets use AES. Then we said wait a second.. the other computer doesnt really have my key so we need to encrypt it..
Also called Public key encryption
1977
Rivest–Shamir–Adleman (RSA)
Diffie–Hellman key exchange protocol
DSS (Digital Signature Standard), which incorporates the Digital Signature Algorithm
ElGamal
Various elliptic curve techniques
Various password-authenticated key agreement techniques
Paillier cryptosystem
RSA encryption algorithm (PKCS#1)
Cramer–Shoup cryptosystem
YAK authenticated key agreement protocol
