## Description

This software implements a X.509 certificate parser, annotated using
ACSL annotations for verification with Frama-C (version 18/Argon).

## Building

The main [Makefile](Makefile) is in the root directory, and compiling is
as simple as executing:

<pre>
	$ make
</pre>

This will compile different elements in the [build](build/) directory:

  * the x509-parser.o object file
  * the x509-parser binary, which can be used on a DER certificate (or
    a concatenation of such elements)

## Validating

The main [Makefile](Makefile) has targets to run several static analyzers.

### Frama-C

To verify the project with [Frama-C](https://frama-c.com/), use the `frama-c`
target:

<pre>
	$ make frama-c
</pre>

Frama-C must have been installed prior to calling that target. Installing
Frama-C can be done using OPAM. More details can be found on
[Frama-C](https://frama-c.com/) project website. Frama-C may also be
available as a common package on your distribution.

### IKOS

To verify the project with [IKOS](https://github.com/NASA-SW-VnV/ikos), use the
`ikos` target:

<pre>
	$ make ikos
</pre>

IKOS must have been installed prior to calling that target.
See the [installation instructions](https://github.com/NASA-SW-VnV/ikos/tree/master/doc/install).
