Question

So I have a certificate chain stored in STACK_OF(X509).
This is what I did with it :

STACK_OF(X509) *chain = SSL_get_peer_cert_chain(ssl);

X509_STORE_CTX* newCert = X509_STORE_CTX_new();
if(newCert){
    X509_STORE_CTX_set_chain(newCert, chain);
    std::cout << X509_verify_cert(newCert) << std::endl;
}
std::cout << "ERROR : " << X509_STORE_CTX_get_error(newCert) << std::endl;

The issue is that the X509_verify_cert(newCert) returns -1 meaning the initialization of the X509_STORE_CTX was not down properly. What am I missing?

I guess, this is related to Use of STACK_OF(X509).

You shouldn’t copy only half of the source code at apps/verify.c. If you look deeper, you will find, among other lines,

 286         if(!X509_STORE_CTX_init(csc,ctx,x,uchain))
