…n updating config.yml
during first boot, if there is no salt or key in the board, the key derivation creation flow will start. During this flow, the User has to enter a password with length between 8 and 12 characters, which is then used to generate a key. This key is stored in SPIFFS, and it is used to encrypt and decrypt services secrets during boot.

During boot, if there is no encryption key stored in SPIFFS, users are prompted to provide a password to create a new encryption key. If a salt is available in
config.ymlit will be used to generate the key, otherwise a new one will be created.For more details, see Key derivation function.
After submiting the password form, the encryption key is created and stored in SPIFFS, and the salt is written as a Base32 encoded string to
config.yml, which is stored in the SD card.
