Resum

DescripcióPublic key making.svg	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.

Altres versions	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.

actual	04:26, 19 maig 2007	426 × 384 (14 Ko)	Davidgothberg	One more try, now using "Arial, Bold, 24" instead of "Arial Black, 22".
	04:22, 19 maig 2007	426 × 384 (13 Ko)	Davidgothberg	Trying with new font like Geni suggested. Now with the new terminology too.
	03:44, 19 maig 2007	409 × 384 (15 Ko)	Geni	again
	03:41, 19 maig 2007	409 × 384 (14 Ko)	Geni	attempt to fix 2 all this still PD
	03:36, 19 maig 2007	409 × 384 (13 Ko)	Geni	trying to fix
	03:08, 19 maig 2007	409 × 384 (13 Ko)	Davidgothberg	Reverted to earlier revision
	03:06, 19 maig 2007	426 × 384 (10 Ko)	Davidgothberg	Argh! Previous image did not render right on Wikipedia. Trying new version saved in slightly different way...
	03:02, 19 maig 2007	426 × 384 (13 Ko)	Davidgothberg	Slight change of terminology. User Birkett pointed it out and the Google test confirms it. "Key making function" -> "Key generation function"
	20:43, 21 ago 2006	409 × 384 (13 Ko)	Davidgothberg	Slightly improved image. (Damn, this non-wysiwyg!)
	20:39, 21 ago 2006	409 × 384 (13 Ko)	Davidgothberg	Slightly improved image.
