coreHTTP basic TLS demo "TLS Handshake fails"

Libraries
,
1

Hello,
I am trying to do a basic server authentication from provided demo for windows simulator.
I tried with httpbin.org with certificate provided over here. It was working fine.
I tried with another web server e.g example 1, example 2
I exported these certificates as shown in the image below

Screenshot 2024-04-03 104814
Screenshot 2024-04-03 1048141113×881 34.3 KB

and added in the header.
I also viewed some other forum post about MQTT auth TLS handshake failures and tried to with SNI 0 and 1 , but still I am facing Handshake error.
Also, I have enabled support for TLS1.3 in mbedtls_config.h
demo_config.h (9.1 KB)
mbedtls_config.h (145.4 KB)
Logs for simulator

The interface that will be opened is set by "configNETWORK_INTERFACE_TO_USE", which
should be defined in FreeRTOSConfig.h
Attempting to open interface number 2.
Successfully opened interface number 2.

Hey Ashvajit, sorry you’re seeing these issues.
Since the log you’re sharing has the error code

89 6592 [DemoTask] [ERROR] [MbedtlsTransport] [tlsHandshake:606] Failed to perform TLS handshake: mbedTLSError= SSL - A fatal alert message was received from our peer : <No-Low-Level-Code>.

Have you verified if the HTTP server you’re accessing will respond to your TLS 1.3 communications when using your host OS’s CLI? I know that I’ve seen some servers aren’t supporting communication when using that protocol yet. Trying to connect to the server using your host OS would help determine if there is an issue with the FreeRTOS Demo or if there is a different issue.

Hi,

I tried with openssl command and I am getting following response.

Thanks for trying that out
Looking through your mbedtls_config.h I see that you’re not defining #define MBEDTLS_USE_PSA_CRYPTO, while attempting to use TLS 1.3. Per this mbedtls github thread I’m not sure if MbedTLS supports TLS 1.3 communications when not using MBEDTLS_USE_PSA_CRYPTO.

Is there a specific reason you are not using the mbedtls_config_v3.5.1.h that is used by default in the coreHTTP Mutual Auth demo?

EDIT: Additionally, have you tried enabling MBEDTLS_SSL_TLS1_3_COMPATIBILITY_MODE?

Yes, I am using the mbedtls_config_v3.5.1.h
I have attached it and tried enabling both

but still getting handshake error.

Hi @skptak ,
I also tried to change the value of MPI and RSA KEY length but it also didn’t help.
I am getting failure from server Hello case. Where It validates Hello response from server.

Do you have any other HTTPS server where, I can test, besides what I have mentioned ?
Please do let me know if basic authentication works.

Thanks

Sorry for the delay in getting back to you. I wanted to test the code locally and didn’t have access to a windows machine at the time.
I was able to run the demo when connecting to the AWS IoT Core. Which leads me to believe it’s a difference in the server you’re connecting to.

I noticed that you’re connecting to port 443 on your other servers, which would enable the Application-Layer Protocol Negotiation (ALPN) in the demo. I’m wondering if this could be causing your issue, as it could set potentially incorrect algorithm exchanges.

I tried with httpbin.org with certificate provided over here. It was working fine.

Want to make sure I understand what you’re saying here. Did you run the demo while connecting to httpbin.org with the democonfigROOT_CA_PEM set to the AWS root CA?

Can you set the logging level to LOG_DEBUG in demo_config.h and transport_mbedtls.c, and enable MBEDTLS_DEBUG_C? That might help pinpoint the exact issue you’re facing.

Hi @skptak ,
Thanks for replying back.
Yes, it did work for the httpbin.org as it is using same certificate as its root CA certificate. As mentioned below.

httpbin_cert
httpbin_cert972×762 27.7 KB

But for the httpbun.com there is different certificate as shown here.

httpbun_cert
httpbun_cert935×705 28.4 KB

Meanwhile, I also tried to fetch the ALPN for httpbun.com with command, but I don’t think it would be a problem, I guess.

Looking at the log you sent it appears you’re sending Amazon’s IoT ALPN protocol name to a third party server.

I’m thinking this in part because you are receving a MBEDTLS_ERR_SSL_FATAL_ALERT_MESSAGE error back from the server after sending your handshake message.

Where if this ALPN protocol name is not what the httpbun server is expecting this could be the cause of your failure. Your curl of the endpoint when using tls1.3 also shows an inability to access the issuer cert.

verify error:num=20:unable to get local issuer certificate

This doesn’t seem like an issue with the FreeRTOS code, but an issue with connecting to the server you are using. I would try connecting to the AWS IoT core to determine if you can connect to that endpoint correctly. You could try using a third party python library that implements a TLS 1.3 echo server locally for futher testing.

10

I have also tried sending “h2” as ALPN.

It might be working with AWS IoT core and httpbin.org but it is not able to connect to any other than that. I have commented out the ALPN part from the example code and tried but still I failed to connect.

I have captured some data on Wireshark. But I was not able to send the log file, this might help.
ws_capture.zip (201.9 KB)

I need to plore more on pyhton as I have not worked on that before. Meanwhile, please let me know if the wireshark logs are useful finding anything related to tls handshake.

11

This is a huge capture and I cannot find any meaningful information from it. Did you use a filter to only capture the communication with your intended server?

Is it working with AWS IoT Core or not? Assuming it is working with AWS IoT Core, the most likely issue if the credentials you are using. I’d recommend using some other tool to establish a connection using the same credentials to verify that the credentials are correct.

12

Sorry for sharing the whole session but I was not sure what specifically I need to look for. But I have filtered the capture with _ws.col.protocol == "TLSv1.2" for checking Hello messages between client and server but was not able to figure out what was wrong with it.

I have tried to connect that server using Postman and I am getting desired response.

13

At the very least you need to share your device IP and server IP so that we can filter the relevant communication.

14

My IP in the provided logs is 10.25.10.16 and server’s IP is 20.31.111.109

15

When I filter the communication with 20.31.111.109, I see the following sequence -

image1636×198 18.1 KB

The above sequence indicates that the server is closing connection (TCP RST) in response to a Client Hello message from the device. Here is the content of the Client Hello message -

image914×579 19.7 KB

Can you also capture network traffic in the case when you are able to successfully communicate (using postman) with the server? This way we can compare the contents of Client Hello and try to see if there is any difference.

16

Sure,
Here’s the capture of the postman connecting to the same client.

Ip provided remains same.
postman_ws_capture.zip (366.1 KB)

17

The major difference I see between the 2 versions is that the working version is using TLS1.3:

image
image1568×662 27.5 KB

Is it possible that the server requires TLS1.3? Have you tried enabling TLS1.3?

18

Yes, I have already enabled TLS 1.3.
For now, I tried disabling TLS 1.2 and I am still not able to connect.
Here’s the capture for TLS 1.3. Also, I would like to mention that in this capture I found that the initial client hello starts with TLS1.2.
tls_1_3_ws_capture.zip (100.1 KB)

19

Then it is not TLS 1.3, right?

20

the later part of the handshake there are TLS 1.3 messages, but version is tls1.2.
