Enterprise CA TLS 1.2 Template

Hey,

I'm looking to sign a requested certificate from an application through our Enterprise Root CA.
The third party application is only supported to run on TLS1.2 for SSL Communication, so is there a way to sign this certificate request with our CA using a template settings to have it compatible with TLS1.2 instead of the common SSLv3.

Thanks in advance for your input on the subject.

Actually using iiscrypto tool to set to best practice will already allow TLS1.2. As long as the cipher in the link is as what is in the CSR for encryption and key exchange, TLS1.2 will already be supported. I do not think you need any special template at your CA as long as your CA is also supporting TLS and have SSLV3 and below disabled.

Cipher suite

Example - how to enable TLS v1.2 for IIS to increase the cipher strength to 256-bits.

wire protocol (SSLv2 or TLS 1.3) has nothing to do with RSA certificate used for key initialisation.

TLS 1.2 cipher should have the below hence the reordering will allow the system to take those as priority ones
