Re: DCMTK TLS and certificates use

Just putting in my two cents on this topic. Based on my limited knowledge on how the situation is working out with TLS, I would still say - "It is rapidly gaining popularity". Much of this has to do with laws and regulatory compliances that medical devices need to meet for selling their pr...

Re: TLS - Windows Certificate Store

Thanks Marco for taking time to clarify my query. We are trying to limit the use of physical files in our implementation and use the store for certificate management. I have already explored the possibility of exporting to openssl. Also, I get the point regarding the number of root certificates in s...

TLS - Windows Certificate Store

Hi,

Can someone provide an insight on the possibility of using certificates from Windows Certificate Store ?
Is it possible to check the same using the existing tools that have TLS support?
Any guidance will be valuable.

Thanks & Regards,
Amal

Re: OpenSSL 3.0.0

Hi Jörg, Thanks for checking on this query. I am not really looking for the binaries, am planning to upgrade openssl to 3.0.0 version from 1.1.1l for our DICOM library. Since 3.0.0 is a new branch was thinking will wait till official dcmtk used 3.0.0 version. This would also help in case of any comp...

Re: Secure Connection issue

Thanks Marco for the reply. I forgot to mention that I am using dcmtk version 3.6.5 in my earlier query. I could not find the setBuiltInDHParameters() function inside the source. Still I tried adding the below code to DcmTLSTransportLayer::DcmTLSTransportLayer(T_ASC_NetworkRole networkRole, const ch...
