2016-04-06ssl: Add option signature_algsIngela Anderton Andin
In TLS-1.2 The signature algorithm and the hash function algorithm used to produce the digest that is used when creating the digital signature may be negotiated through the signature algorithm extension RFC 5246. We want to make these algorithm pairs configurable. In connections using lower versions of TLS these algorithms are implicit defined and can not be negotiated or configured. DTLS is updated to not cause dialyzer errors, but needs to get a real implementation later.

2016-02-22ssl: Include options form connect/listen/accept in connection_information/[1,2]Ingela Anderton Andin
Make sure that options only relevant for one role (client|server) is set to undefined when the other role is invoked. As there are many options to ssl, and many are optional, we choose to filter out all undefined options to avoid overwhelming the user with not relevant information. This way there is no need for any special handling of the role specific options which is also nice.
2016-02-17ssl: with verify_none, accept critical extensionsMagnus Henoch
When establishing a TLS connection with {verify, verify_none}, if the server has a certificate with a critical extension, for example a "Netscape Cert Type" extension, certificate verification would fail, which is surprising given that the name of the option suggests that no verification would be performed. With this change, certificate extensions marked as critical are ignored when using verify_none.

* rlipscombe/rl-ssl-options: Ensure single 'raw' option is handled correctly Pass 'raw' options through OTP-13166
2015-10-02Pass 'raw' options throughRoger Lipscombe
In Erlang R16B03-1, I've been passing raw options to ssl:listen as follows, and it's been working fine: % The constants are defined elsewhere. LOpts = [{raw, ?IPPROTO_TCP, ?TCP_MAXSEG, <<MSS:32/native>>} | ...], {ok, LSocket} = ssl:listen(0, LOpts) In Erlang 17.3, this fails with {option_not_a_key_value_tuple,{raw,6,2,<<64,2,0,0>>}} I originally reported this in http://erlang.org/pipermail/erlang-questions/2014-October/081226.html I need to pass this particular raw option to ssl:listen, because it needs to be applied when the socket is first opened -- between inet:open and prim_inet:listen -- it cannot be applied later by setopts. This means that it needs to be done by inet_tcp:listen/2 -- well, actually by inet:open/8, but... Otherwise it's racey -- a client could connect between prim_inet:listen and the setopts call. The MSS option is advertised in the SYN,ACK packet, and can't be changed later.
2015-09-16ssl: Better timeout gaurdsIngela Anderton Andin
2015-09-16ssl: Improve shutdown logicIngela Anderton Andin
Add possibility to downgrade an SSL/TLS connection to a tcp connection, and give back the socket control to a user process. Add application setting to be able to change fatal alert shutdown timeout, also shorten the default timeout. The fatal alert timeout is the number of milliseconds between sending of a fatal alert and closing the connection. Waiting a little while improves the peers chances to properly receiving the alert so it may shutdown gracefully.

* ferd/deny-client-renegotiation: Add disable client-initiated renegotiation option Conflicts: lib/ssl/doc/src/ssl.xml lib/ssl/src/ssl.erl OTP-12815
2015-06-03Add disable client-initiated renegotiation optionFred Hebert
Client-initiated renegotiation is more costly for the server than the client, and this feature can be abused in denial of service attempts. Although the ssl application already takes counter-measure for these (via cooldown periods between renegotiations), it can be useful to disable the feature entirely. This patch adds the `{client_renegotiation, boolean()}' option to the server-side of the SSL application (defaulting to `true' to be compatible with the current behaviour). The option disables the ability to do any renegotiation at all in the protocol's state, reusing the existing denial code, but without opening the code path that sets up a timed message to eventually reopen it up.
2015-05-12ssl: Refactored and corrected sni_fun handlingIngela Anderton Andin
Dialyzer warned about the incorrect match of Packets. Code was refactored and the problem avoided in the process. Dialyzer warned that the empty tuple is not a function as the contract said it should be. Changed the handling of the sni_fun default value to be undefined and added it to the contract.
2015-05-12ssl: add option sni_funQijiang Fan
The newly added function sni_fun allows dynamic update of SSL options like keys and certificates depending on different SNI hostname, rather than a predefined rules of SSL options.
2015-05-12ssl: add ssl:connection_information/[1,2]Qijiang Fan
This commit adds a new function, ssl:connection_information/[1,2] to retrive the connection information from a SSLSocket. And also, this deprecates a function ssl:connection_info/1, and reimplements connection_info/1 with the new function.

2015-03-17ssl: Add TLS-ALPN supportLoïc Hoguin
This commit adds support for RFC7301, application-layer protocol negotiation. ALPN is the standard based approach to the NPN extension, and is required for HTTP/2. ALPN lives side by side with NPN and provides an equivalent feature but in this case it is the server that decides what protocol to use, not the client. When both ALPN and NPN are sent by a client, and the server is configured with both ALPN and NPN options, ALPN will always take precedence. This behavior can also be found in the OpenSSL implementation of ALPN. ALPN and NPN share the ssl:negotiated_protocol/1 function for retrieving the negotiated protocol. The previously existing function ssl:negotiated_next_protocol/1 still exists, but has been deprecated and removed from the documentation. The tests against OpenSSL require OpenSSL version 1.0.2+.

2014-09-09ssl, public_key: Add new option partial_chainIngela Anderton Andin
Check that the certificate chain ends with a trusted ROOT CA e.i. a self-signed certificate, but provide an option partial_chain to enable the application to define an intermediat CA as trusted. TLS RFC says: "unknown_ca A valid certificate chain or partial chain was received, but the certificate was not accepted because the CA certificate could not be located or couldn't be matched with a known, trusted CA. This message is always fatal." and also states: "certificate_list This is a sequence (chain) of certificates. The sender's certificate MUST come first in the list. Each following certificate MUST directly certify the one preceding it. Because certificate validation requires that root keys be distributed independently, the self-signed certificate that specifies the root certificate authority MAY be omitted from the chain, under the assumption that the remote end must already possess it in order to validate it in any case." X509 RFC says: "The selection of a trust anchor is a matter of policy: it could be the top CA in a hierarchical PKI, the CA that issued the verifier's own certificate(s), or any other CA in a network PKI. The path validation procedure is the same regardless of the choice of trust anchor. In addition, different applications may rely on different trust anchors, or may accept paths that begin with any of a set of trust anchors."

2014-05-07ssl: SSL/TLS version input list shall not be order dependentIngela Anderton Andin
2014-04-16ssl: Select supported cipher suites for the negotiated SSL/TLS-versionIngela Anderton Andin
When selecting the available cipher suites for the server all cipher suites for the highest supported SSL/TLS-version would be selected, and not all supported for the negotiated SSL/TLS-version. This could lead to that faulty clients could negotiate cipher suites that they can not support. This change will enable the faulty client to negotiate another cipher suite that it can support.

HonorCipherOrder as implemented in Apache, nginx, lighttpd, etc. This instructs the server to prefer its own cipher ordering rather than the client's and can help protect against things like BEAST while maintaining compatability with clients which only support older ciphers. This code is mostly written by Andrew Thompson, only the test case was added by Andreas Schultz.
