System compatibility with TLS 1.2 RRS feed

  • Question

  • Hi Team,

    We have a application in VB.Net (MDES) which communicate with other application (CCR) to get the encrypted Credit card number. In our application we are using DLL to call the Webservice of  CCR application and get the encrypted data.

    The other application is moving to TLS 1.2 from TLS 1.1

    The DLL we are using is in .NET 4.5.2 and we are able to establish connection from DLL to CCR (CCR is on TSL 1.2) to get the encrypted data.

    However we registered the DLL in our application however we are not able to get any response from CCR which is on TLS 1.2.

    When we migrate CCR to TLS 1.1 it is working fine. 

    Is it because our main application is on VB.Net it is not able to establish connection to CCR which is on TLS 1.2 ?
