An asymmetric key (the so-called public-private key pair) is often used in an electronic signature. The private key is known only to the user and its confidentiality is one of the most important elements of signature security. The public key is open and an electronic signature is created with its use. In asymmetric encryption methods, both the sender and receiver have a separate pair of keys. The sender uses the recipient’s public key to encrypt the message. The addressee can read it using his secret private key. The asymmetry results from the fact that data encrypted with the mentioned pair of the public keys can only be decrypted using the private key of the pair. When a user wants to receive confidential messages in encrypted form via e-mail, he creates a key pair with special software. Then it reveals the public key or sends it to people who intend to send it encrypted messages. The other activities are performed by the sender and the recipient as described below.
