[openssl-users] openssl 1.1.1 opaque structures

[Richard Levitte]

Did you ever get an answer to that?  There is a call BN_num_bytes(),
so the fix should be this:

    *var = rc_vmalloc(BN_num_bytes(bn));
    (*var)->l = BN_bn2bin(bn, (unsigned char *)(*var)->v);

Cheers,
Richard ( you should probably study include/openssl/bn.h in depth )
