Subject: [PATCH 2/2] Extend the password hash format

Several new fields were added to support hash from /etc/shadow.
Affected variables: MokAuth, MokDelAuth, MokPW, MokPWStore

[Hash Method][Interation Count][Salt Size][Salt][hash]

Besides, the password is converted to a 8-bit char array before
hashing with salt.
