wg set private-key does not give any output with wg show

[mvesin]

When running wg set wg0 private-key <(wg genkey), no error is received but wg show wg0 or wg showconf wg0 does not show output for the private-key or the public-key (or maybe own-public-key is the public-key, but then it is not displayer in wg

Am I missing something or is there an issue ?
