gnupg: Agent GENKEY

 
 2.6.3 Generating a Key
 ----------------------
 
 This is used to create a new keypair and store the secret key inside the
 active PSE -- which is in most cases a Soft-PSE. A not-yet-defined
 option allows choosing the storage location.  To get the secret key out
 of the PSE, a special export tool has to be used.
 
         GENKEY [--no-protection] [--preset] [<cache_nonce>]
 
    Invokes the key generation process and the server will then inquire
 on the generation parameters, like:
 
         S: INQUIRE KEYPARM
         C: D (genkey (rsa (nbits  1024)))
         C: END
 
    The format of the key parameters which depends on the algorithm is of
 the form:
 
          (genkey
            (algo
              (parameter_name_1 ....)
                ....
              (parameter_name_n ....)))
 
    If everything succeeds, the server returns the *public key* in a SPKI
 like S-Expression like this:
 
           (public-key
             (rsa
       	 (n <mpi>)
       	 (e <mpi>)))
 
    Here is an example session:
         C: GENKEY
         S: INQUIRE KEYPARM
         C: D (genkey (rsa (nbits  1024)))
         C: END
         S: D (public-key
         S: D   (rsa (n 326487324683264) (e 10001)))
         S  OK key created
 
    The '--no-protection' option may be used to prevent prompting for a
 passphrase to protect the secret key while leaving the secret key
 unprotected.  The '--preset' option may be used to add the passphrase to
 the cache using the default cache parameters.
 
    The '--inq-passwd' option may be used to create the key with a
 supplied passphrase.  When used the agent does an inquiry with the
 keyword 'NEWPASSWD' to retrieve that passphrase.  This option takes
 precedence over '--no-protection'; however if the client sends a empty
 (zero-length) passphrase, this is identical to '--no-protection'.
