It appears with 11.36 keytool is cranking out 3072 bit requests. Even if I specifiy
-keysize 2048 the CSR is exactly the same as the default with no keysize specified and can’t be accepted by the CA (2048 or 4096 allowed). I did open a support case but since this question came up for the windows cvcerttool as well seems like many of us would like the ability to specify keysize.
Does anyone know if this is by design or if there is any enhancement request in the pipeline yet?
thanks

+10doh, genkey needs the keysize not certreq.
