dwm_enc_key_clear

Clears the encryption key and disables the encryption option if enabled. It does nothing if the key is not set.

Caution

Normally, this call writes to internal flash when setting a new value. Hence, it should not be used frequently and can take hundreds of milliseconds in the worst case! It requires a reset for the new configuration to take effect.
