Summary

Description

Public-key cryptography / asymmetric cryptography, creating a key pair. A big random number is used to create a key pair. When the keys have been made the big random number is thrown away. Without knowledge of the random number it should be "impossible" to create the private key from the public key. (In many algorithms it is also "impossible" to create the public key from the private key once the random number has been thrown away.) The public key can be freely published to the world.

Note that most key making functions internally need more than one random number. To handle this the "big random number" usually is fed as a seed to a cryptographically secure random number generator that then produces many pseudo random numbers for the key making function.

This image is part in a series of images showing the four basic public-key cryptography operations: Creating a key pair, encrypting, signing, and creating a shared secret. Note that no single cryptosystem can do all three operations: For instance RSA can do encryption and signing, while Diffie–Hellman can create shared secrets.
