What Principles are Important When You're Developing a Cipher? The key difference between the two is that symmetric algorithms use the same key for encryption and decryption, while asymmetric algorithms use different keys for encryption and decryption.įor a general overview of cryptography and the difference between symmetric and asymmetric ciphers, check out this article. Symmetric algorithms are also known as ‘secret key’ algorithms, and asymmetric algorithms are known as ‘public key’ algorithms. Today, there are two basic types of algorithms - symmetric and asymmetric. It's often used to protect data in transit.Įncryption is a two way function – that is, you need to be able to undo whatever scrambling you’ve done to the message. And encryption involves encoding messages so that only the intended recipient can understand the meaning of the message. Cryptography is the science of using codes and ciphers to protect messages. ![]()
