BDEMOEC
BDEMOEC provides the same functionality as BDEMO, but uses elliptic curve for its
algorithms. The algorithm used for sealing and opening digital envelopes is ECAES to
encrypt the DES symmetric key. Digital signatures are created and verified using
ECDSA with SHA1.
A set of elliptic curve parameters are hard-coded in the demo along with two key
pairs generated with that curve. A new key pair can be generated, but since the size of
the key pair is dependent on the elliptic curve parameters used, the user cannot
specify the desired key size.

Running BDEMOEC

Command Line mode
To start BDEMOEC, enter the following after the system prompt:
> bdemoec
Input Redirection mode
You may also run BDEMOEC in input redirection mode where your responses to the
menu prompts are read from a file. For example, to read commands from a file named
testin, enter the following after the system prompt:
> bdemoec -s < testec
Notice that this uses < to redirect testin as the input to BDEMOEC. The -s option to
BDEMOEC eliminates the menu prompts when BDEMOEC is taking input from a file.
Any line that is blank or begins with ’#’ is ignored. This means that the file used in
response file mode may contain blank lines and comment lines that begin with ’#’.

Using BDEMOEC

The menu options and procedures for BDEMOEC are identical for those for BDEMO.
See “Using BDEMO” on page 329 for a description of the menu commands.
