How to change CSR key size?


I want to generate a CSR for my server.  I have used STRUST to do this. When I sent generated CSR to One of the CA providers, Its giving me the below error:

  • Your CSR contains a key size that is no longer considered secure. Security best practices require a minimum key size of 2048 bits. Please submit a new CSR with a minimum 2048 bit key size.

Can somebody tell me how to change the key size?

yep, 1024 bits these days is not enough. You should be able to change it to higher number with parameter sec/rsakeylengthdefault. By default it's 1024 which I think it should be increased by SAP.
