licensing: fix license info for Crypto/{bn,ec}
This code was part of Dolphin's relicensing from v2 to v2+ a while back,
we just never updated these copyright headers. I double-checked that
segher gave us permission to relicense this code to v2+ on 2015-05-16.

treewide: convert GPLv2+ license info to SPDX tags
SPDX standardizes how source code conveys its copyright and licensing
information. See https://spdx.github.io/spdx-spec/1-rationale/ . SPDX
tags are adopted in many large projects, including things like the Linux
kernel.

JosJuice 2137fb7813 Externals: Add zstd
I had to rename Source/Common/Compiler.h because the VS build
confuses it with Externals/zstd/lib/common/compiler.h otherwise.

Lioncash d8f6d60189 Compiler: Rename UNUSED macro to DOLPHIN_UNUSED
UNUSED is quite a generic macro name and has potential to clash with
other libraries, so rename it to DOLPHIN_UNUSED to prevent that, as well
as make its naming consistent with the force inline macro

Lioncash 03414e8e84 Common: Add header for compiler-specifics
Instead of globbing things under an ambiguous Common.h header, move
compiler-specifics over to Compiler.h. This gives us a dedicated home
for anything related to compilers that we want to make functional across
all compilers that we support.

This moves us a little closer to eliminating Common.h entirely.

Léo Lam fff1db9730 Common: Add Random utilities
This makes it easier to generate random numbers or fill a buffer with
random data in a cryptographically secure way.

This also replaces existing usages of RNG functions in the codebase:

* <random> is pretty hard to use correctly, and std::random_device does
  not give enough guarantees about its results (it's
  implementation-defined, non cryptographically secure and could be
  deterministic on some platforms).
  Doing things correctly is error prone and verbose.

* rand() is terrible and should not be used especially in crypto code.

Léo Lam 355b1b5d5b ec: Improve readability and clarity
- Move all of the ec functions into the Common::ec namespace.

- Give the public functions better names and some usage information.

- Move all of the "elt" related functions into an "elt" class including
  all of the arithmetic operations, so that the logic becomes clearer
  and feels less like assembly.

  This also makes it much more obvious what the parameters are, instead
  of only using unsigned char* (which doesn't tell anything about what
  the pointer is used for or the size).

- Similarly, add a new "Point" class and move point functions there.
  Overload the arithmetic operators to make calculations easier to read

Léo Lam e83591f188 ec: Avoid exposing internal function 2018-05-20 19:59:26 +02:00
Léo Lam b9dd94b9b2 bn: Use int instead of u32 for sizes
The loops relied on unsigned integer overflow, which is not immediately
obvious. Replace them with less clever variants that are clearer.

Also implement bn_compare using std::memcmp.

Léo Lam f8fb9e2d03 IOS: Implement IOSC-like API
This prevents the IOS crypto code and keys from being spread over
the codebase. Things only have to be implemented once, and can be
used everywhere from the IOS code.

Additionally, since ES exposes some IOSC calls directly (DeleteObject
and Encrypt/Decrypt), we need this for proper emulation.

Currently, this only supports AES key objects.

IOS unpersonalises device-specific ("personalised") tickets prior to
storing them on the NAND.
