Added support for OpenSSL 1.1 Some KOpenSSLProxy methods have been renamed to be consistent with OpenSSL 1.1 API names and to prevent hidden API changes. To ensure API / ABI compatibility, the original methods are still included but have been marked as deprecated. + SSLv23_client_method => TLS_client_method + X509_STORE_CTX_set_chain => X509_STORE_CTX_set0_untrusted + sk_dup => OPENSSL_sk_dup + sk_free => OPENSSL_sk_free + sk_new => OPENSSL_sk_new + sk_num => OPENSSL_sk_num + sk_pop => OPENSSL_sk_pop + sk_push => OPENSSL_sk_push + sk_value => OPENSSL_sk_value Additional methods have been added to KOpenSSLProxy to support the new OpenSSL 1.1 API functions that provide access to the (now) opaque SSL structures. Compatibility with OpenSSL < 1.1 is handled internally in KOpenSSLProxy. + BIO_get_data + DSA_get0_key + DSA_get0_pqg + EVP_PKEY_base_id + EVP_PKEY_get0_DSA + EVP_PKEY_get0_RSA + RSA_get0_key + X509_CRL_get0_lastUpdate + X509_CRL_get0_nextUpdate + X509_OBJECT_get0_X509 + X509_OBJECT_get_type + X509_STORE_CTX_get_current_cert + X509_STORE_CTX_get_error + X509_STORE_CTX_get_error_depth + X509_STORE_CTX_set_error + X509_STORE_get0_objects + X509_STORE_set_verify_cb + X509_get0_signature + X509_getm_notAfter + X509_getm_notBefore + X509_subject_name_cmp + _SSL_session_reused + _SSL_set_options Method "KSSL::setSession" has been renamed to "KSSL::takeSession" and its functionality has changed: the session is now transferred from the argument object to the invoked object. Since it is only used internally in TDE and the functionality is different, the method with the previous name has not been preserved.
