Gary Ching-Pang Lin 7dc45398d6 Request a password to verify the key list 
The password must contain 8 characters at least and 16 characters
at most and will be hashed with the key list altogether. The keys
in MokNew won't be allowed to be enrolled unless the user provides
the correct password.

README 

shim is a trivial EFI application that, when run, attempts to open and
execute another application. It will initially attempt to do this via the
standard EFI LoadImage() and StartImage() calls. If these fail (because secure
boot is enabled and the binary is not signed with an appropriate key, for
instance) it will then validate the binary against a built-in certificate. If
this succeeds and if the binary or signing key are not blacklisted then shim
will relocate and execute the binary.

shim will also install a protocol which permits the second-stage bootloader
to perform similar binary validation. This protocol has a GUID as described
in the shim.h header file and provides a single entry point. On 64-bit systems
this entry point expects to be called with SysV ABI rather than MSABI, and
so calls to it should not be wrapped.

To use shim, simply place a hex dump of the public certificate in cert.h
and build it with make.
