[openssl-users] openssl 1.1.1 opaque structures

[priya p]

Hi Richard,

I am unable to get the API to access bn->top value  or any bn members in
openssl 1.1.1 .
Can you help me with the pointers to those APIs ?

And  I dont see "lh_OPENSSL_CSTRING_new " function in
"include/openssl/safestack.h"
?
Please correct me if I am wrong .

Thanks,
Priya
