Description
The path to the user keyfile. The keyfile contains user keys used to encrypt the partitions. The size of user key can be 128 or 256 bits. The 128-bit key can be used only for run-time loaded partitions.
Example
In the following example, FPD partition uses the key source as
user_key2, so the .nky file for this
partition must have the user_key2 from the
userkeys file as the key0. This
key0 from the .nky file is then used by
Bootgen for encryption. The PLM uses the user_key2 programmed by
pmc_data during decryption.
