About
-----

Kore (https://kore.io) is a web application platform for writing scalable,
concurrent web based processes in C or Python.

It is built with a "secure by default" approach. It is fully privilege
separated while using strong security features at the operating system level
such as seccomp, pledge, unveil and more.

Today Kore is used in a variety of applications ranging from high assurance
cryptographic devices, machine-learning stacks and even in the aerospace
industry.

From embedded platforms all the way to high performance servers. *Kore scales.*

Key Features
------------
* Supports SNI
* Supports HTTP/1.1
* Websocket support
* Privseps by default
* TLS enabled by default
* Optional background tasks
* Built-in parameter validation
* Optional asynchronous PostgreSQL support
* Optional support for page handlers in Python
* Reload private keys and certificates on-the-fly
* Automatic X509 certificates via ACME (with privsep)
* Private keys isolated in separate process (RSA and ECDSA)
* Default sane TLS ciphersuites (PFS in all major browsers)
* Modules can be reloaded on-the-fly, even while serving content
* Worker processes sandboxed on OpenBSD (pledge) and Linux (seccomp)
* Event driven (epoll/kqueue) architecture with per CPU worker processes
* Build your web application as a precompiled dynamic library or single binary

And lots more.

Requirement for asynchronous curl (optional)
* libcurl (7.64.0 or higher)

Requirements for background tasks (optional)
* pthreads

Requirements for pgsql (optional)
* libpq

Requirements for python (optional)
* Python 3.6+

Requirements for lua support (optional)
* Lua 5.4+

Normal compilation and installation:

```
$ cd kore
$ make
# make install
```

If you would like to build a specific flavor, you can enable
those by setting a shell environment variable before running **_make_**.

* LUA=1 (compiles in LUA support)
* ACME=1 (compiles in ACME support)
* CURL=1 (compiles in asynchronous curl support)
* TASKS=1 (compiles in task support)
* PGSQL=1 (compiles in pgsql support)
* DEBUG=1 (enables use of -d for debug)
* NOHTTP=1 (compiles Kore without HTTP support)
* NOOPT=1 (disable compiler optimizations)
* JSONRPC=1 (compiles in JSONRPC support)
* PYTHON=1 (compiles in the Python support)
* TLS_BACKEND=none (compiles Kore without any TLS backend)

Note that certain build flavors cannot be mixed together and you will just
be met with compilation errors.

Example applications
