Hello,
when an ENGINE implements the RSA key generation the current
implementation of the 'genrsa' command doesn't use the funcion reference
of that ENGINE for this. This reference should be stored in the RSA
struct and is passed to the RSA_generate_key_ex() function.
The problem is that the RSA strcut is initialized via RSA_new() with the
default function before the ENGINE interface was set up properly. The
patch below fixes this.
Regards,
Ralf Vennemann
