I feel the way this sentence is written provides us with the wrong impression of cryptographic keys.
I believe cryptographic keys are made up of zeros and ones which are represented in hexadecimal format to make it more easily read by people.
But, the official online curriculum says “strings of numbers”.
MHOO you are correct at the machine level they are ones and zeros but when most folk discuss keys, they talk about them ad numbers of letters. Also presenting the keys as letters or numbers is more efficient than presenting them as ones and zeros.
Others?
