# lws minimal http client certinfo

This demonstrates how to dump information from the peer
certificate largely independent of the tls backend.

The application goes to https://warmcat.com and receives the page data.

Before receiving the page it dumps information on the server's cert.

This works independently of the tls backend being OpenSSL or mbedTLS.

However the public keys cannot be compared between the two tls
backends, since they produce different representations.

## build

```
 $ cmake . && make
```

## usage

Commandline option|Meaning
---|---
-d <loglevel>|Debug verbosity in decimal, eg, -d15
-l| Connect to https://localhost:7681 and accept selfsigned cert
--h1|Specify http/1.1 only using ALPN, rejects h2 even if server supports it

```
