SPL requires key hash to verify and flash it to OTP/EFUSE.
- hash@c: n, e, c
- hash@np: n, e, np
/ {
signature {
key-dev {
required = "conf";
algo = "sha256,rsa2048";
rsa,np = <...>;
rsa,c = <...>;
rsa,modulus = <...>;
rsa,exponent-BN = <...>;
...
key-name-hint = "dev";
hash@np {
algo = "sha256";
value = <0x0934bc4d 0xfbc31ffe 0x9224d6c2 0x1a3aa280 0x881d881e 0xe2006246 0x01b9e724 0x35c03428>;
};
hash@c {
algo = "sha256";
value = <0x08962385 0x34585e06 0x0b73a496 0x374b148d 0xa2700a75 0x4aae08ad 0xb2a324a3 0x95ee6b52>;
};
};
};
...
};
But after processed by scripts/fit.sh, only one of "hash@c" and "hash@np" would be left.
