Hi Cool Curl people. I am trying to extract the public key of a self signed cert...Here is how I am doing, and what the problem is:
I set a verify call back function, in which I do: X509 *cert = X509_STORE_CTX_get_current_cert(x509_ctx); int depth = X509_STORE_CTX_get_error_depth(x509_ctx); int err = X509_STORE_CTX_get_error(x509_ctx); I check cert pointer, non NULL; I check depth, which is ZERO; I check err, which is 18 (X509_V_ERR_DEPTH_ZERO_SELF_SIGNED_CERT) All good. EVP_PKEY *pubKey = X509_get_pubkey(cert); I check pubKey, which is non NULL; As I dereference pubKey as pubKey->pkey.rsa, the pointer turns out to be NULL :(. Am I doing something wrong? When there is an error, does OPENSSL still expose the cert public key? How would I retrieve a public key of the certificate the peer is presenting to me? Thanks for any hints... Dirceu
