# lws minimal http client JIT Trust This example turns off any existing trusted CAs and then tries to connect to a server, by default, warmcat.com. It validates the remote certificates using trusted CAs from a JIT Trust blob compiled into the code. ## build ``` $ cmake . && make ``` ## usage Commandline option|Meaning ---|--- -d |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 --server |set server name to connect to -k|Apply tls option LCCSCF_ALLOW_INSECURE -j|Apply tls option LCCSCF_ALLOW_SELFSIGNED -m|Apply tls option LCCSCF_SKIP_SERVER_CERT_HOSTNAME_CHECK -e|Apply tls option LCCSCF_ALLOW_EXPIRED -v|Connection validity use 3s / 10s instead of default 5m / 5m10s --nossl| disable ssl connection --user | Set Basic Auth username --password | Set Basic Auth password ``` $ ./bin/lws-minimal-http-client-jit-trust --h1 --server ebay.com --path / ==1302866== [2021/06/17 14:33:54:7500] U: LWS minimal http client JIT Trust [-d] [-l] [--h1] [2021/06/17 14:33:54:7956] N: LWS: 4.2.99-v4.2.0-70-g80e7e39bae, loglevel 1031 [2021/06/17 14:33:54:7960] N: NET CLI SRV H1 H2 WS MbedTLS ConMon IPv6-absent [2021/06/17 14:33:54:8165] N: ++ [wsi|0|pipe] (1) [2021/06/17 14:33:54:8227] N: ++ [vh|0|netlink] (1) [2021/06/17 14:33:54:8319] N: ++ [vh|1|default||-1] (2) [2021/06/17 14:33:55:0107] N: ++ [wsicli|0|GET/h1/ebay.com] (1) [2021/06/17 14:33:56:0291] N: ++ [vh|2|jitt-7F69A044||-1] (3) [2021/06/17 14:33:56:0355] E: CLIENT_CONNECTION_ERROR: server's cert didn't look good, invalidca (use_ssl 0x20000061) X509_V_ERR = 24: CA is not trusted [2021/06/17 14:33:56:0376] N: ++ [wsicli|1|GET/h1/ebay.com] (2) [2021/06/17 14:33:56:0746] N: -- [wsicli|0|GET/h1/ebay.com] (1) 1.061s [2021/06/17 14:33:56:7555] N: lws_client_reset: REDIRECT www.ebay.com:443, path='/', ssl = 1, alpn='http/1.1' [2021/06/17 14:33:57:0205] N: ++ [vh|3|jitt-DFF2B5B4||-1] (4) [2021/06/17 14:33:57:0208] E: CLIENT_CONNECTION_ERROR: server's cert didn't look good, invalidca (use_ssl 0x1) X509_V_ERR = 24: CA is not trusted [2021/06/17 14:33:57:0210] N: ++ [wsicli|2|GET/h1/ebay.com] (2) [2021/06/17 14:33:57:0288] N: -- [wsicli|1|GET/h1/ebay.com] (1) 991.119ms [2021/06/17 14:33:57:7528] N: lws_client_reset: REDIRECT www.ebay.com:443, path='/', ssl = 1, alpn='http/1.1' [2021/06/17 14:33:58:1564] U: Connected to 195.95.193.127, http response: 200 [2021/06/17 14:33:58:1637] U: RECEIVE_CLIENT_HTTP_READ: read 209 [2021/06/17 14:33:58:1796] U: RECEIVE_CLIENT_HTTP_READ: read 197 [2021/06/17 14:33:58:1822] U: RECEIVE_CLIENT_HTTP_READ: read 1014 [2021/06/17 14:33:58:1847] U: RECEIVE_CLIENT_HTTP_READ: read 1024 [2021/06/17 14:33:58:1851] U: RECEIVE_CLIENT_HTTP_READ: read 1022 [2021/06/17 14:33:58:2748] U: RECEIVE_CLIENT_HTTP_READ: read 242 [2021/06/17 14:33:58:2782] U: RECEIVE_CLIENT_HTTP_READ: read 1014 [2021/06/17 14:33:58:2784] U: RECEIVE_CLIENT_HTTP_READ: read 1024 [2021/06/17 14:33:58:2785] U: RECEIVE_CLIENT_HTTP_READ: read 1024 ...

In one console window run the server and in the other ``` $ lws-minimal-http-client -l --nossl --path /secret/index.html --user user --password password ``` The Basic Auth credentials for the test server are literally username "user" and password "password".
