- [Instructor] Asymmetric cryptography solves issues of scalability by giving each user a pair of keys for use in encryption and decryption operations. The RSA algorithm was one of the earliest asymmetric cryptographic algorithms and it's still used today. The RSA algorithm gains its name from the initials of the three creators of the algorithm, considered three of the pioneers of cryptography. Ron Rivest, the creator of the RC4 cipher, Adi Shamir, and Len Adleman first published their invention of the algorithm in 1977. It's pretty impressive that an algorithm created four decades ago is still in use today. When a new user wants to use RSA cryptography to communicate with others, they create a new key pair. Now there's a lot of complex math involved in creating the keys, but the underlying principle that you really need to understand is that the user selects two very large prime numbers, and those prime numbers are used…
