The 2nd parameter to fread() namely "size" specifies the size, in
bytes of each element to be read, and the 3rd parameter namely "count"
specifies the number of elements, each one with a size of "size" bytes.
size_t fread ( void * ptr, size_t size, size_t count, FILE * stream );
But in the function file2bin() the values passed to "size" and "count"
are reversed causing the function to return an error eventhough the file
was sucdessfully read.
Pass the right values to "size" and "count" parameters for fread() in
the function file2bin().

Wasn't this problem addressed by Vitaly's patch. Please look at commit
c89e8508864b ("ima-evm-utils: Fix reading of sigfile").
You are right Mimi. I missed the patch posted by Vitaly. Sorry for the
duplicate one.
Looks like Vitaly's change hasn't been merged to "master" branch yet in
https://github.com/pevik/ima-evm-utils
Only after the release would it be in master. Until then it would be
in next, which it isn't either. Can I add your Reviewed-by tag on
this patched?
Sure.
