Hi,

I am trying to encrypt data on my rabbitmq communication. On the rabbitmq server end I am using the openssl and on the client end I cant use openssl but I can use mbedtls. I am using mbedtls-2.26.0 version in my rabbimq-c client .

The certificate is generated via https://github.com/michaelklishin/tls-gen The certificate is valid and has no issue because the communication works fine when I use the ssl_client2 and ssl_server2 applications from the mbedtls-2.26.0\programs. The communication works fine when I use the rabbitmq openssl client and openssl server.

But when I try to use the rabbitmq openssl server and ssl_client2 from mbedtls-2.26.0\programs the connection is reset. I think it’s a config issue but I am not able to figure out the solution or the rootcause. I am not sure if I can use mbedtls client with openssl server. Could you please help me in this.

Below is the log from wireshark. Attached is the log from sslclient2 program. After the certificate is verified the broker resets the connection TCP 60271 → 5671 [SYN] Seq=0 Win=65535 Len=0 MSS=65475 WS=256 SACK_PERM=1 TCP 5671 → 60271 [SYN, ACK] Seq=0 Ack=1 Win=65535 Len=0 MSS=65475 WS=256 SACK_PERM=1 TCP 60271 → 5671 [ACK] Seq=1 Ack=1 Win=2618880 Len=0 TLSv1.2 Client Hello TCP 5671 → 60271 [ACK] Seq=1 Ack=305 Win=2618880 Len=0 TLSv1.2 Server Hello, Certificate, Server Key Exchange, Certificate Request, Server Hello Done TCP 60271 → 5671 [ACK] Seq=305 Ack=1976 Win=2616832 Len=0 TLSv1.2 Certificate TCP 5671 → 60271 [ACK] Seq=1976 Ack=945 Win=2618112 Len=0 TLSv1.2 Client Key Exchange TCP 5671 → 60271 [ACK] Seq=1976 Ack=1088 Win=2618112 Len=0 TLSv1.2 Certificate Verify TCP 5671 → 60271 [ACK] Seq=1976 Ack=1173 Win=2618112 Len=0 TLSv1.2 Change Cipher Spec TCP 5671 → 60271 [ACK] Seq=1976 Ack=1179 Win=2618112 Len=0 TLSv1.2 Encrypted Handshake Message TCP 5671 → 60271 [ACK] Seq=1976 Ack=1216 Win=2617856 Len=0 TLSv1.2 Change Cipher Spec, Encrypted Handshake Message TCP 60271 → 5671 [ACK] Seq=1216 Ack=2019 Win=2616832 Len=0 TLSv1.2 Application Data TCP 5671 → 60271 [ACK] Seq=2019 Ack=1245 Win=2617856 Len=0 TLSv1.2 Application Data TCP 60271 → 5671 [ACK] Seq=1245 Ack=2048 Win=2616832 Len=0 TLSv1.2 Encrypted Alert TCP 60271 → 5671 [ACK] Seq=1245 Ack=2071 Win=2616832 Len=0 TCP 5671 → 60271 [RST, ACK] Seq=2071 Ack=1245 Win=0 Len=0
