Prepare & Upload File System

• Create cert.der and key.der (RSA or ECC) for HTTPS

  • RSA: openssl req -x509 -subj "/CN=ESP32-CAM" -nodes -days 9999 -keyout data/key.pem -out data/cert.pem -newkey rsa:2048
  • ECC: openssl req -x509 -subj "/CN=ESP32-CAM" -nodes -days 9999 -keyout data/key.pem -out data/cert.pem -newkey ec:<(openssl ecparam -name prime256v1)
  • Convert to DER:
    • openssl x509 -in data/cert.pem -outform DER -out data/cert.der
    • openssl rsa -in data/key.pem -outform DER -out data/key.der
    • openssl ec -in data/key.pem -outform DER -out data/key.der

• Copy data/settings.template.txt to data/settings.txt and edit

  • esp.name: display name
  • camera.*: camera settings

• Copy data/secret.template.txt to data/secret.txt and edit

  • esp.salt: random value (eg dd if=/dev/random bs=50 count=1 | base64)
  • esp.pwdHash: sha256 hash of concatination of salt and user password ((echo -n ${esp_salt} ; echo -n 'mypassword') | sha256sum)
  • wlan.ap-*: settings for wifi soft access point
  • wlan.st-*: settings for wifi station mode

pio run -t uploadfs
