Thank you! I observe that in 1.1.x everything's fine - the structure evp_pkey_methods_st is opaque, but both getters and setters are defined and available.
In 1.0.2 the structure is already opaque, the setters are present, but some getters are absent. Which makes it quite hard to work with members of this structure. I think this is a bug, and two possible remedies INHO are: add getter functions for the members, or add/move this structure from evp-int.h to evp.h (so it's no longer opaque). What is your opinion? Thanks!
