Hi Janos,
Yes, it's related to the same issue as mentioned in my previous email.
Is there any specific information required from our side - please let me know in which scenarios "Unknown CA" would be returned?
Regards, Prakash

Hi Satya,
Is this issue related to the one described in your previous email “[mbed-tls] EAP TLS - TLSv1.2 Record Layer: Alert (Level: Fatal, Description: Unknown CA)”?
Kind regards,

Hi Janos,
Kindly note that I have already provided the same in my initial email. Please refer the same for your reference:
Please note that we need to give CN value different for Root and Server / Client (since I am trying got mutual trusted certificate. You can also verify the same in below way:
*First console :*
# openssl s_server -cert crt1/server.crt -key crt1/server.key -WWW -port 12345 -CAfile crt1/trusted_ca.eap.pem -verify_return_err
or -Verify 1
verify depth is 1, must return a certificate
Using default temp DH parameters
ACCEPT
*Second Console: *
#touch test.txt
# openssl s_server -cert crt1/server.crt -key crt1/server.key -WWW -port 12345 -CAfile crt1/trusted_ca.eap.pem -verify_return_err
or -Verify 1
verify depth is 1, must return a certificate
Using default temp DH parameters
ACCEPT
*On First Console we receive:*
# openssl s_server -cert crt1/server.crt -key crt1/server.key -WWW -port 12345 -CAfile crt1/trusted_ca.eap.pem -verify_return_err
or -Verify 1
verify depth is 1, must return a certificate
Using default temp DH parameters
ACCEPT

*verify return:1*
*depth=0 C = US, ST = CA, L = Somewhere, O = Someone, CN = Foobar*

Hi Prakash,
Thank you for sharing the details about how you generated the certificates. Could you please share the command line for the server and the client as well?
Kind regards,
Janos

Hi,
Please note that while using MBedTLS 3.6.0, when we are trying to verify server / client connection using self-signed mutually trusted certificates we are always getting a CA Unknown Certificate error code 46 alert message.
Root CA Key # openssl genrsa -des3 -out ca.key.pem 2048 Generating RSA private key, 2048 bit long modulus (2 primes) ..+++++ ....+++++ e is 65537 (0x010001) Enter pass phrase for ca.key.pem:^1234^ Verifying - Enter pass phrase for ca.key.pem:^1234^

So we have used Root CA Certificatet as trusted certificate but during handshake steps we see client reporting "Certificate Unknown'' alert error message 46?
TLSv1.2 Record Layer: Alert (Level: Fatal, Description: Certificate Unknown) Description: Certificate Unknown (46)
Can you please let us know the issue we are doing in creating the certificates or it can also be some wrong steps / configuration while compiling the 3.6.0 release?
