/*
 * This program does 5 separate functions.  By default, it does them all.
 * It can be told to do any subset of them.
 * It does them in this order:
 *
 * 1. Generate file of CRMF cert requests.
 *     Generates 2 keys pairs, one for signing, one for encryption.
 *     Can generate RSA or DSA (XXX - DSA is only useful for signing).
 *     Generate a cert request for each of the two public keys.
 *     Generate a single CRMF cert request message that requests both certs.
 *     Leave the generated CRMF request message in file
 *         configdir/CertReqMessages.der
 *
 * 2. Decode CRMF Request(s) Message.
 *    Reads in the file   configdir/CertReqMessages.der
 *    (either generated by step 1 above, or user supplied).
 *    Decodes it.  NOTHING MORE.  Drops these decoded results on the floor.
 *    The CMMF response (below) contains a completely unrelated cert.  :-(
 *
 * 3. CMMF "Stuff".
 *  a)  Generates a CMMF response, containing a single cert chain, as if 
 *    it was a response to a received CRMF request.  But the cert is 
 *    simply a user cert from the user's local soft token, whose 
 *    nickname is given in the -p option.  The CMMF response has no
 *    relationship to the request generated above.  The CMMF message
 *    is placed in configdir/CertRepContent.der.
 *  b)  Decodes the newly generated CMMF response found in file
 *    configdir/CertRepContent.der and discards the result.  8-/
 *  c)  Generate a CMMF Key Escrow message
 *      needs 2 nicknames: 
 *      It takes the public and private keys for the cert identified
 *      by -p nickname, and wraps them with a sym key that is in turn
 *      wrapped with the pubkey in the CA cert, whose nickname is 
 *      given with the -s option.
 *      Store the message in configdir/KeyRecRepContent.der
 *  d)  Decode the CMMF Key Escrow message generated just above.
 *      Get it from file configdir/KeyRecRepContent.der
 *      This is just a decoder test.  Results are discarded.
 *
 * 4. Key Recovery
 *    This code does not yet compile, and what it was intended to do
 *    has not been fully determined.
 *
 * 5. Challenge/Response.
 *    Haven't analyzed this code yet.
 *

/* KNOWN BUGS:
** 1. generates BOTH signing and encryption cert requests, even for DSA keys.
**
** 2. Does not verify the siganture in the "Proof of Posession" in the
**    decoded cert requests.  It only checks syntax of the POP.
** 3. CMMF "Stuff" should be broken up into separate steps, each of 
**    which may be optionally selected.
