6.2. Generating a Private Key Warning

Warning: The specified password is considered insecure. Intel recommends that at least 13 characters of password be used. You are recommended to change the password by using the OpenSSL executable.
openssl ec -in <input PEM> -out <output PEM> -aes256


This warning is related to the password strength and displays when trying to generate a private key by issuing the following commands:

quartus_sign --family=agilex --operation=make_private_pem \
--curve=secp3841 root.pem


Use the openssl executable to specify a longer and thus stronger password.
