I hve ported tpm2_tools to windows and and am able to run tpm2_getrandom,
tpm2_createprimary etc. I am using the ctx file generated by
tpm2_createprimary to run tpm2_create.
HEre are the commands i used:
tpm2_createprimary -c primary.ctx (works)tpm2_create -C primary.ctx -u
obj.pub -r obj.priv (fails)
This is the error i get:
ERROR: Found magic 0x40000001 did not match expected magic of 0xbadcc0de!
WARN: The loaded tpm context does not appear to be in the proper format,
assuming old format, this will be converted on the next save.
ERROR: Could not load tpm context file
ERROR: Failed to load_tpm_context_file()
ERROR: Unable to run
C:\Users\arunsu\source\repos\tpm2-tools-4.0\vstudio\x64\Debug\tpm2-create.exe
I see from files.c that the magic is hardcoded.
/**
* This is the magic for the file header. The header is organized
* as a big endian U32 (BEU32) of MAGIC followed by a BEU32 of the
* version number. Tools can define their own, individual file
* formats as they make sense, but they should always have the header.
*/
static const UINT32 MAGIC = 0xBADCC0DE;
Is this a windows vs Linux issue? Should i change the magic value?
