In [[symmetric key cryptography]], both parties must possess a secret key which they must exchange prior to using any encryption. Distribution of secret keys has been problematic until recently, because it involved face-to-face meeting, use of a trusted courier, or sending the key through an existing encryption channel. The first two are often impractical and unsafe, while the third depends on the security of a previous key exchange. |
