Hi,
I need to set custom accelerated functions for bn_mod_exp methods in
openssl 1.1.1, while upgrading for openssl 1.0.2. Here's the code snippet
() :
--
static DH_METHOD Intoto_DH_Method;
static RSA_METHOD Intoto_RSA_Method;
static DSA_METHOD Intoto_DSA_Method;
void updatePublicKeyMethods()
{
Intoto_DH_Method = *(DH_get_default_method());
Intoto_DH_Method.bn_mod_exp = Intoto_DH_mod_exp;
DH_set_default_method(&Intoto_DH_Method);
Intoto_RSA_Method = *(RSA_get_default_method());
Intoto_RSA_Method.bn_mod_exp = Intoto_RSA_mod_exp;
RSA_set_default_method(&Intoto_RSA_Method);
Intoto_DSA_Method = *(DSA_get_default_method());
Intoto_DSA_Method.bn_mod_exp = Intoto_DSA_mod_exp;
DSA_set_default_method(&Intoto_DSA_Method);
return;
}
--
As RSA_METHOD,DSA_METHOD & DH_METHOD objects are Opaque now , Can anyone
help me with what would be the replacement for above code ??
Thanks,
Prudvi
