For reference: The following GPGME fucntion can be used:

 -- Function: gpgme_error_t gpgme_op_import_keys (gpgme_ctx_t CTX,
          gpgme_key_t *KEYS)
     The function ‘gpgme_op_import_keys’ adds the keys described by the
     ‘NULL’ terminated array KEYS to the key ring of the crypto engine
     used by CTX.  This function is the general interface to move a key
     from one crypto engine to another as long as they are compatible.
     In particular it is used to actually import and make keys permanent
     which have been retrieved from an external source (i.e.  using
     ‘GPGME_KEYLIST_MODE_EXTERN’).  (1)

     Only keys of the the currently selected protocol of CTX are
     considered for import.  Other keys specified by the KEYS are
     ignored.  As of now all considered keys must have been retrieved
     using the same method, that is the used key listing mode must be
     identical.

     After the operation completed successfully, the result can be
     retrieved with ‘gpgme_op_import_result’.

     The function returns the error code ‘GPG_ERR_NO_ERROR’ if the
     import was completed successfully, ‘GPG_ERR_INV_VALUE’ if KEYDATA
     if CTX or KEYDATA is not a valid pointer, ‘GPG_ERR_CONFLICT’ if the
     key listing mode does not match, and ‘GPG_ERR_NO_DATA’ if no keys
     are considered for export.

Note that this works only for GPGSM (GPGME_PROTOCOL_CMS) because there
is no need for this with GPG (GPGME_PROTOCOL_OPENPGP).


Shalom-Salam,
