The issue with this is that station_config::password is exactly 64 chars so you will have no ending zero... IMHO the correct fix would be to declare uint8 password[65]; in esp_sta.h, and signal a bug to espressif.

WPA passphrases are 8-63 ASCII characters by 802.11 spec so this is not a bug.

strcpy((char*)config.password, password.c_str());
