Esp32 Flash Encryption

Hi ,
Trying to implement flash encryption with pre-generated key on esp32.
Does the first boot after enabling flash encryption always need to be plaintext ?( this worked for me)
Can I increment FLASH_CRYPT_CNT by one and directly flash encrypted binaires?( this did not work)

Reading Efuse Block 1

Hi,
Is it possible to read the value of flash enc key from efuse block using following api:

esp_efuse_read_block(EFUSE_BLK1,enc_key_256,0x0000, 256);

Currently I am getting all values as zero , since read protect is enable. Is there a way to disable it?

Thanks,
Dhiraj
