CC3235MODASF: unable to connect with HTTPS using RSA 4096

Part Number: CC3235MODASF
Other Parts Discussed in Thread: CC3235MODSF, UNIFLASH

Hi,

I am using the CC3235MODSF launchpad and making the HTTPS post request. I am able to successfully connected to the https server using RSA 2048 encryption.

but I am getting an error while connecting to the below server which is using RSA 4096 encryption.

I have downloaded the root CA certificate and burned the certificate using uniflash.

I have updated the correct date and time using the SNTP server.

Below is the error in Putty.

  

I have used the below code:

HTTPClient_extSecParams httpClientSecParams;
httpClientSecParams.rootCa = SSL_CA_CERT;
httpClientSecParams.clientCert = NULL;
httpClientSecParams.privateKey = NULL;

Could you please help me to resolve this issue

Regards,

Robert

  • Hi Robert,

    Please make sure that you have uploaded latest Service Pack inside CC3235. I think RSA 4096bit keys should be supported since SDK 3.30 and particular ServicePack tided with this SDK version.
