From 057c279cb4d5c16990570d281bd1bc568796cbb2 Mon Sep 17 00:00:00 2001 From: Martijn Otto Date: Thu, 14 Jun 2018 23:44:48 +0100 Subject: epee: add SSL support RPC connections now have optional tranparent SSL. An optional private key and certificate file can be passed, using the --{rpc,daemon}-ssl-private-key and --{rpc,daemon}-ssl-certificate options. Those have as argument a path to a PEM format private private key and certificate, respectively. If not given, a temporary self signed certificate will be used. SSL can be enabled or disabled using --{rpc}-ssl, which accepts autodetect (default), disabled or enabled. Access can be restricted to particular certificates using the --rpc-ssl-allowed-certificates, which takes a list of paths to PEM encoded certificates. This can allow a wallet to connect to only the daemon they think they're connected to, by forcing SSL and listing the paths to the known good certificates. To generate long term certificates: openssl genrsa -out /tmp/KEY 4096 openssl req -new -key /tmp/KEY -out /tmp/REQ openssl x509 -req -days 999999 -sha256 -in /tmp/REQ -signkey /tmp/KEY -out /tmp/CERT /tmp/KEY is the private key, and /tmp/CERT is the certificate, both in PEM format. /tmp/REQ can be removed. Adjust the last command to set expiration date, etc, as needed. It doesn't make a whole lot of sense for monero anyway, since most servers will run with one time temporary self signed certificates anyway. SSL support is transparent, so all communication is done on the existing ports, with SSL autodetection. This means you can start using an SSL daemon now, but you should not enforce SSL yet or nothing will talk to you. --- contrib/epee/include/net/abstract_tcp_server2.inl | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'contrib/epee/include/net/abstract_tcp_server2.inl') diff --git a/contrib/epee/include/net/abstract_tcp_server2.inl b/contrib/epee/include/net/abstract_tcp_server2.inl index 39d6911e3..f5548c585 100644 --- a/contrib/epee/include/net/abstract_tcp_server2.inl +++ b/contrib/epee/include/net/abstract_tcp_server2.inl @@ -900,7 +900,7 @@ PRAGMA_WARNING_DISABLE_VS(4355) m_thread_index(0), m_connection_type( connection_type ), new_connection_(), - m_ssl_context({boost::asio::ssl::context(boost::asio::ssl::context::sslv23), {}}) + m_ssl_context({boost::asio::ssl::context(boost::asio::ssl::context::tlsv12), {}}) { create_server_type_map(); m_thread_name_prefix = "NET"; @@ -939,14 +939,14 @@ PRAGMA_WARNING_DISABLE_VS(4355) } //--------------------------------------------------------------------------------- template - bool boosted_tcp_server::init_server(uint32_t port, const std::string address, epee::net_utils::ssl_support_t ssl_support, const std::pair &private_key_and_certificate_path, const std::list &allowed_certificates, bool allow_any_cert) + bool boosted_tcp_server::init_server(uint32_t port, const std::string address, epee::net_utils::ssl_support_t ssl_support, const std::pair &private_key_and_certificate_path, const std::list &allowed_certificates, const std::vector> &allowed_fingerprints, bool allow_any_cert) { TRY_ENTRY(); m_stop_signal_sent = false; m_port = port; m_address = address; if (ssl_support != epee::net_utils::ssl_support_t::e_ssl_support_disabled) - m_ssl_context = create_ssl_context(private_key_and_certificate_path, allowed_certificates, allow_any_cert); + m_ssl_context = create_ssl_context(private_key_and_certificate_path, allowed_certificates, allowed_fingerprints, allow_any_cert); // Open the acceptor with the option to reuse the address (i.e. SO_REUSEADDR). boost::asio::ip::tcp::resolver resolver(io_service_); boost::asio::ip::tcp::resolver::query query(address, boost::lexical_cast(port), boost::asio::ip::tcp::resolver::query::canonical_name); @@ -980,7 +980,7 @@ PRAGMA_WARNING_DISABLE_VS(4355) PUSH_WARNINGS DISABLE_GCC_WARNING(maybe-uninitialized) template - bool boosted_tcp_server::init_server(const std::string port, const std::string& address, epee::net_utils::ssl_support_t ssl_support, const std::pair &private_key_and_certificate_path, const std::list &allowed_certificates, bool allow_any_cert) + bool boosted_tcp_server::init_server(const std::string port, const std::string& address, epee::net_utils::ssl_support_t ssl_support, const std::pair &private_key_and_certificate_path, const std::list &allowed_certificates, const std::vector> &allowed_fingerprints, bool allow_any_cert) { uint32_t p = 0; @@ -988,7 +988,7 @@ DISABLE_GCC_WARNING(maybe-uninitialized) MERROR("Failed to convert port no = " << port); return false; } - return this->init_server(p, address, ssl_support, private_key_and_certificate_path, allowed_certificates, allow_any_cert); + return this->init_server(p, address, ssl_support, private_key_and_certificate_path, allowed_certificates, allowed_fingerprints, allow_any_cert); } POP_WARNINGS //--------------------------------------------------------------------------------- -- cgit v1.2.3
