Special Characters in WiFi PW #21

Closed Blueforcer closed 1 year ago

Blueforcer commented 1 year ago

It seems that special characters in wifi password are not saved correctly. i have a "&-" at the end of my password.

If i print out my PW in console https://github.com/cotestatnt/esp-fs-webserver/blob/4022ff91751d7ea3f218fccfa80a2e408c2ba93f/src/esp-fs-webserver.cpp#L158 its not there anymore.

It looks like the saving function has maybe an encoding problem. Like mentioned here? https://github.com/tzapu/WiFiManager/issues/804#issuecomment-453546791

Hi @Blueforcer and thanks for your advice. I need to to investigate deeper

Just for research purposes: each password will be cut at an & e.g. 3EZeF!&tU_rB0-6vy8$T7ghlS5P1&- only 3EZeF! is left

Just for research purposes:

This is a very useful information indeed... I suspect the & character causes the POST request handler to interpret the following as if it were a new parameter passed in the request body.

I have to change the way ssid and password are passed to the microcontroller (if possible also avoiding that the password is visible in clear text)
