I have code signed everything on my computer. python, the arduino IDE, the ota script. in every case the output from codesign -dvvv is this
Executable=/Users/amelvin/Arduino/esp8266/tools/espota.py
Identifier=espota
Format=generic
CodeDirectory v=20100 size=115 flags=x0(none) hashes=1+2 location=embedded
Hash type=sha1 size=20
CDHash=c6c79c6ddb2ddc59f050130c279bff6e82f63da7
Signature size=1501
Authority=mycodesigning
Signed Time=3 Nov 2015, 14:28:47
Info.plist=not bound
TeamIdentifier=not set
Sealed Resources=none
Internal requirements count=2 size=136
none of it makes any difference. the cert mycodesigning is trusted for everything. i've restarted my machine.. from what i can see this should work...
Unpack the tool into `tools` directory (the path will look like `<home_dir>/Arduino/tools/ESP8266FS/tool/esp8266fs.jar`)
