Error in SSL connection between controller and generator (v12.50): dh key too small

Dear team,

 

I'm using the latest version of LoadRunner v12.50 (community edition) and upon connecting from a controller to a load generator over a proxy using SSL, I get the following error: "dh key too small". I found that this error is caused by a change in the latest version of OpenSSL, which does not accept DH keys smaller than 768 bit anymore (see link below). I found that LoadRunner still uses a 512-bit DH key, located in \dat\cert. Could you please advise me how to solve this issue?

 

Thanks!

Hi,

 

You can generate a DH param file using open ssl command line, and replace LR's dh512.pem (in both controller and LG).

 

openssl dhparam -out dh512.pem 2048
