How to set "e" in RSA structure ?

[Swamy J-S]

Recently i upgraded openssl from 1.0.2 to 1.1.0. As RSA structure is opaque in new opnessl i made some modifications in my code as follows :

Old Code
RSA* rsa = EVP_PKEY_get1_RSA(PKey);
if(NULL != rsa)
{
if(!BN_set_word(rsa->e, 65537) || !EVP_PKEY_set1_RSA(PKey, rsa))
--------------------------------------------------------------------------------------------------
New Code
RSA* rsa = EVP_PKEY_get1_RSA(PKey);
BIGNUM *e_new = BN_new();
if(NULL != rsa)
{
if(!BN_set_word(e_new, 65537) || !EVP_PKEY_set1_RSA(PKey, rsa))

But Now "e" variable is not set in 'rsa', So how to set "e" inside rsa? Pls suggest me corresponding API

Thanks and Regards,
SWAMY J S
