Summary
| Description |
Public-key cryptography / asymmetric cryptography, signing. A message that is signed (encrypted) with the private key can be verified (decrypted) with the public key. Since the public key is public, anyone can verify the signature. The public key cannot create such signatures. Security depends on the secrecy of the private key. Original illustration by David Göthberg, Sweden. Released by David as public domain. |

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. |
