Symmetric and asymmetric encryption differ in how they use cryptographic keys. In this video, Mike Chapple explains the differences between the two approaches.
- [Instructor] There are many different kinds … of encryption algorithm, … and there are different ways … that we can categorize those algorithms. … Two of the major categories … are symmetric and asymmetric algorithms. … You're probably already familiar … with the concept of symmetry, … meaning that two things are the same. … Symmetric shapes have two sides … that when divided along an axis, are identical. … Similarly, the structure of the human face is symmetric. … In cryptography, … symmetry relates to keys rather than shapes, … and we have two categories of encryption algorithms. … In symmetric encryption algorithms, … also known as shared secret encryption algorithms, … the encryption and decryption operations … use the same key. … If one user encrypts a message using the secret key apple, … a second user would have to decrypt the message … using that same key. … It's a shared secret. … Asymmetric encryption algorithms, on the other hand, … use different keys for encryption and decryption. …
