How to set "e" in RSA structure ?

[Swamy J-S <swamy.j-s@xxxxxxxxxx>]

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,
