Summary

DescriptionPublic key encryption.svg	Public-key cryptography / asymmetric cryptography, encryption. Anyone can encrypt using the public key, but only the holder of the private key can decrypt. Security depends on the secrecy of the private key. Original illustration by David Göthberg, Sweden. Released by David as public domain.

Other 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.

A message that is encrypted with the public key can only be decrypted with the secret key. The public key can NOT decrypt the message. This means any one can send encrypted messages to the ow
