Hi all,
I'm trying to verify the signature of a FIT image in barebox.
I created the FIT image with the following .its file:
...
configurations {
default = "config@1";
config@1 {
description = "Boot Raspian kernel";
kernel = "kernel";
fdt = "fdt-1";
signature@1 {
algo = "sha256,rsa2048";
key-name-hint = "dev";
sign-images = "fdt", "kernel";
...
Verifying the Hashes for the kernel and fdt-1 works fine ("hash OK" for both
images) , but when I try to verify the signature I get the follwoing error:
ERROR: FIT: hashed-strings start not found in
/configurations/config@1/signature@1
I could follow the error back to the fit_verify_signature function in
/common/image-fit.c file, but I don't understand what is causing the error.
Is the function looking for a string called "hashed-strings" in the FIT image
file? I checked the .fit file (with hexdump) and I could only find the string
"hash@1" which barebox uses to verify the signature.
Best regards
Kai
