1d2f86949b crypto: Various crypto fixes for quickstart guide 2018-10-14 21:57:52 -04:00

18db0f1107 partition_data_manager: Reserve and insert data within output vector in DecryptPackage2() 
We can just reserve the memory then perform successive insertions
instead of needing to use memcpy. This also avoids the need to zero out
the output vector's memory before performing the insertions.

We can also std::move the output std::vector into the destination so
that we don't need to make a completely new copy of the vector, getting
rid of an unnecessary allocation.

Additionally, we can use iterators to determine the beginning and end
ranges of the std::vector instances that comprise the output vector, as
the end of one range just becomes the beginning for the next successive
range, and since std::vector's iterator constructor copies data within
the range [begin, end), this is more straightforward and gets rid of the
need to have an offset variable that keeps getting incremented to
determine where to do the next std::memcpy.

20a95f7e90 partition_data_manager: Remove unused std::map instance within DecryptPackage2() 
Aside from emplacing elements into the map, the map itself is never
actually queried for contained data.

283f111f7d partition_data_manager: Take package2_keys by const reference 
These are only ever read from, so we don't need to make a copy of all
the keys here.

461cd4b81c partition_data_manager: Move IV data to where it's needed in DecryptPackage2() 
Given it's only used in one spot and has a fairly generic name, we can
just specify it directly in the function call. This also the benefit of
automatically moving it.

8e8fbbc19b partition_data_manager: Dehardcode array bounds 
Instead, we can make it part of the type and make named variables for
them, so they only require one definition (and if they ever change for
whatever reason, they only need to be changed in one spot).

49f255e0b5 partition_data_manager: Take VirtualFile by const reference in constructor 
Given the VirtualFile instance isn't stored into the class as a data
member, or written to, this can just be turned into a const reference,
as the constructor doesn't need to make a copy of it.

0581db975a partition_data_manager: Amend constructor initializer list order

also prevents compiler warnings about this sort of thing.

f50401aa7f key_manager: Use std::vector's insert() instead of std::copy with a back_inserter 
If the data is unconditionally being appended to the back of a
std::vector, we can just directly insert it there without the need to
insert all of the elements one-by-one with a std::back_inserter.

5323ae4af4 key_manager: Brace long conditional body

214d206020 key_manager: Don't assume file seeks and reads will always succeed 
Given the filesystem should always be assumed to be volatile, we should
check and bail out if a seek operation isn't successful. This'll prevent
potentially writing/returning garbage data from the function in rare
cases.

This also allows removing a check to see if an offset is within the
bounds of a file before perfoming a seek operation. If a seek is
attempted beyond the end of a file, it will fail, so this essentially
combines two checks into one in one place.

b7c947fed3 key_manager: Remove unnecessary seek in DeriveSDSeed() 
Given the file is opened a few lines above and no operations are done,
other than check if the file is in a valid state, the read/write pointer
will always be at the beginning of the file.
