Dear Sir, We had implemented the TLS server and client in C language and worked fine. But when we are trying to connect the server with a Java based client following error occurs When we converted the .cer certificate to .jks using Java keytool and tried to load in java client it is not working. Pls see Attached screenshot
Is it possible to connect a Java client(.jks) with c/c++ based server (.cer) ??
Please help

Hi,
Mbed TLS 2.7 is no longer supported on any platform. We strongly recommend against using unmaintained versions of Mbed TLS, as they have unpatched publicly known security vulnerabilities, and will only have more of them as time passes.
Currently the only maintained version of Mbed TLS are the latest 2.16.x release (though note it's EOL at the end of the calendar year), the latest 2.x.y release, and the latest 3.x.y release. See https://github.com/ARMmbed/mbedtls/blob/development/BRANCHES.md

When we are using the version *mbedtls-2.16.6* with *libiec61850-1.5*, the TLS connection is established successfully. But when we use the *2.7.19*, the connection fails(we renamed *mbedtls 2.7.19* as *mbedtls 2.16* and put in the folder third_party\mbedtls ).
We had occurred following error during the execution of client- server example programs tls_server_example and tls_client_example using 2.7.19 version. During handshaking process till CASE " MBEDTLS_SSL_CLIENT_CHANGE_CIPHER_SPEC " it worked as expected. But In CASE "MBEDTLS_SSL_CLIENT_FINISHED" the return value should be zero. But we got in function mbedtls_ssl_safer_memcmp
mac_peer==41155316 mac_expect==41155356 diff=255 (this value has to be 0 for connection establishment) But we are getting 255 constantly in all runnings.
Kindly help us to resolve the issue. If this issue is due to the non supporting of mbedtls version ?.Thanks in advance. Please let us know the *supporting versions of mbedtls *for *libiec61850-1.5 *.
