#39 fixes the majority of the build warnings in xori. There are a couple outstanding warnings that need further investigation. I see these warnings when building on macos 10.15.3, ubuntu 19.10, and windows server 2019.

Since your program is embeddable and written in Rust, your project (and radeco of course, haha) might benefit from reusing the crate:
https://github.com/radareorg/radeco and https://github.com/radareorg/radeco-lib
It is not yet finished, but should be ready for its first release in about a month.

Running the command line analysis
xori -f [file]
results in following exception:

trying to read this is super annoying right now
failed to run custom build command for
openssl v0.9.24 process didn't exit successfully:

As of now, CFG is displayed in GUI.
It would be of great help if that graph is outputted along with other output files. A lot of papers talk about malware detection using CFG analysis, so providing CFG (which you are generating anyway) is much helpful.
Along with disasm, functions and import files, you can output cfg file which has cfg in form of adjacency matrix or adjacency list.
I've attempted to install Xori on two versions of Windows 10; both the latest and greatest v 1803 as well as the previous version (1709 I believe). Per the requirements:
-Installed Rust from https://static.rust-lang.org/dist/rust-1.28.0-x86_64-pc-windows-gnu.msi
-Downloaded the zip from https://github.com/endgameinc/xori
-Tried installing in CMD window, both with and without Admin privileges using "cargo build --release".
-Also tried installing with the same command in a PowerShell window.
In all cases, I got the attached error message.
It would be nice to provide pre-built binaries and make them available using releases, so users didn't have to install Rust and build it themselves.
Just a friendly suggestion :)
Rather than having a react app why don't you just have a WASM app!!!

The first phrase from README should go as a descritpion:
Xori is an automation-ready disassembly and static analysis library that consumes shellcode or PE binaries and provides triage analysis data.
On modern Linux distros (Ubuntu 18.04, 19.10) that ship with openssl 1.1.x, cargo build
produces this error:

I'm pretty sure this is related to the version of the reqwest
crate we're currently using.
$ grep reqwest Cargo.toml
reqwest = "0.8.5"
For production use, itβs best not to allow all origins. Instead, create a white list of allowed domains, and check each request against the white list.
I noticed yesterday that much of Xori's instruction decoding maps pretty directly to chunks of Capstone's decoding logic. Since that appears to be the case for so much of xori's decoder, does it make sense to use capstone-rs directly?
I noticed in your slides that you mention fixing a few capstone bugs in the process of rewriting, so maybe those fixes could be upstreamed? If the motivator for decoding in rust is avoiding memory bugs another thought might be to see about parcelling out Xori's x86 decoder and seeing about replacing the capstone decoder upstream?
Barring any of that, it would be good to know that Xori's x86 decoding very closely derives from Capstone's implementation, much like Capstone does in indicating its LLVM origins, especially if bugs were found in Xori's decoder to know that they should be upstreamed - even the disassembly mapping tables are the same as Capstone's and those do change from time to time!
(a nice part of capstone-rs as a backend means the bar for supporting any other Capstone-backed arch is a lot easier!)
