the name and location of the file that contains the encrypted data

the name and location of the of the file that contains the encrypted DES key

the name and location of the of the file that contains the IV

the name of the file where the decrypted content should be stored. To print the content to the screen instead, use a hyphen (-) as the file name.

the recipient’s user number

3.BDEMO uses the recipient’s private key to recover the DES key. It then uses the DES key to decrypt the data and saves it to the specified file. If a hyphen was entered as the output file name, it prints the decrypted data to the screen instead of saving it to a file.

Generate a Key Pair

Use BDEMO to generate a new RSA key pair. However, this is only for demonstration purposes, and does not generate cryptographically secure RSA keys. BDEMO will generate an RSA public/private key pair, but the keys are lost when you exit BDEMO.

To generate a key pair:

1.Enter “g” at the top-level menu.

2.You will be prompted in succession for:

the key size in bits

some seed information

3.BDEMO generates the key pair and keeps it as the key pair for User 3. Once a keypair has been generated, you may not generate another during the same BDEMO session.

Depending on the key size and the speed of the computer, key pair generation may take from a few seconds to several minutes.
