After completing this video, the learner will understand the use of the Rivest, Shamir, Adelman (RSA) cryptographic algorithm.
- [Voiceover] 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 is 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 Leonard Adelman 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, he or she…creates a new key pair.…There's a lot of complex math involved in…creating that key pair,…but the underlying principle that you need…to understand is that the user selects…two very large prime numbers that are used…to create the encryption keys.…After going through some mathematical computation,…RSA uses these prime numbers to create a…
