_pppp_uuuu_bbbb_llll_iiii_cccc_kkkk_eeee_yyyy: _gggg_eeee_tttt_pppp_uuuu_bbbb_llll_iiii_cccc_kkkk_eeee_yyyy, _gggg_eeee_tttt_ssss_eeee_cccc_rrrr_eeee_tttt_kkkk_eeee_yyyy - retrieve public or secret key
_gggg_eeee_tttt_pppp_uuuu_bbbb_llll_iiii_cccc_kkkk_eeee_yyyy and _gggg_eeee_tttt_ssss_eeee_cccc_rrrr_eeee_tttt_kkkk_eeee_yyyy get public and secret keys for _n_e_t_n_a_m_e from
the _pppp_uuuu_bbbb_llll_iiii_cccc_kkkk_eeee_yyyy(4) database.
_gggg_eeee_tttt_ssss_eeee_cccc_rrrr_eeee_tttt_kkkk_eeee_yyyy has an extra argument, _p_a_s_s_w_d, used to decrypt the encrypted
secret key stored in the database.
Both routines return _1111 if they are successful in finding the key, _0000
otherwise. The keys are returned as NULL-terminated, hexadecimal
strings. If the password supplied to _gggg_eeee_tttt_ssss_eeee_cccc_rrrr_eeee_tttt_kkkk_eeee_yyyy fails to decrypt the
secret key, the routine will return _1111 but the _s_e_c_r_e_t_k_e_y argument will be
a NULL string.
