2018-12-21ssl: Clean up extension handlingIngela Anderton Andin
Use throw stratgy for erro handling in extension handling. Makes code consistent and easier to refactor. Also fixes bug that an incorrect return value for gen_statem could be created when alert was a result of handling renegotiation info extension.

This change adds the capability to the TLS 1.3 server to process ClientHello messages and answer with ServerHello. Change-Id: I13f6cfac932574300338e7301c6162252a591c70

2018-10-15ssl: Implement Signature Algorithms (TLS 1.3)Péter Dimitrov
Implement handling of the signature algorithms extension described by RFC 8446. This commit updates the behavior of legacy TLS versions to align them with RFC 8446 (TLS 1.3) and RFC 5246 (TLS 1.2). - TLS 1.0/1.1 clients validate the client certificate against the certificate_type field of the CertificateRequest message. - TLS 1.2 client verifies the hash/signature algorithm pair of the client certificate when processing a CertificateRequest. Old behavior only checked the signature algorithms. - TLS 1.2 server verifies that the server certificate is signed by a hash/signature algorithm pair that appears in the "singature_algorithms" or "signature_algorithms_cert" (RFC 8446) extensions of the ClientHello.

2018-09-27ssl: Generalize extensions handlingIngela Anderton Andin
As TLS 1.3 introduces more extensions in other places than in hello messages we like to have generalize extension handling encode/decode with some hello wrappers. Also extend property tests of handshake encod/decode
2018-09-06ssl: Correct compression decodingIngela Anderton Andin
Property testing revealed an decoding error of "compression_methods" in the client hello. As we do not implement any compression methods this has no practical impact.

2018-08-21ssl: Move formatting code to own moduleIngela Anderton Andin
The conversion code for different representations of cipher suites is long an repetitive. We want to hide it in a module that does not have other functions that we like to look at.

2018-07-19ssl: Implement downgrade protection mechanism (TLS 1.3)Péter Dimitrov
If negotiating TLS 1.2, TLS 1.3 servers MUST set the last eight bytes of their Random value to the bytes: 44 4F 57 4E 47 52 44 01 If negotiating TLS 1.1 or below, TLS 1.3 servers MUST and TLS 1.2 servers SHOULD set the last eight bytes of their Random value to the bytes: 44 4F 57 4E 47 52 44 00 Change-Id: If35112f63f42a9af351f4ca9b1846fd3f5b08167
2018-07-19ssl: Update hello state (TLS 1.3)Péter Dimitrov
Update hello state to handle the "supported_versions" extension defined by TLS 1.3: - If "supported_versions" is present in ServerHello, the client will aboirt the handshake with an "illegal_parameter" alert. - If "supported_versions" is present in ClientHello, the server will select a version from "supported_versions" and ignore ClientHello.legacy_version. If it only supports versions greater than "supported_versions", the server aborts the handshake with a "protocol_version" alert. - If "supported_versions" is absent in ClientHello, the server negotiates the minimum of ClientHello.legacy_version and TLS 1.2. If it only supports version greater than ClientHello.legacy_version, the server aborts the handshake with a "protocol_version" alert. Change-Id: I16eef15d77bf21209c6cc103546ddddca518483b

2018-07-02ssl: Add support for stateful loggingPéter Dimitrov
- Introduce stateful logging levels to the ssl application: The SSL option 'log_alert' sets log level to notice/warning if it is set to true/false. Default log level is notice. - Add new SSL option 'log_level' that overrides the value of 'log_alert'. Default value is notice. - 'log_level' debug triggers verbose logging of TLS protocol messages and logging of ignored alerts in DTLS. Change-Id: I28d3f4029a5d504ec612abe4b9ae0b7d9b115197

2017-05-06ssl: Add hostname check of server certificateIngela Anderton Andin
When the server_name_indication is sent automatize the clients check of that the hostname is present in the servers certificate. Currently server_name_indication shall be on the dns_id format. If server_name_indication is disabled it is up to the user to do its own check in the verify_fun.

2017-02-08ssl: Avoid SSL/TLS hello format confusionIngela Anderton Andin
Valid SSL 3.0 or TLS hellos might accidentally match SSL 2.0 format (and sometimes the other way around before inspecting data) so we need to match SSL 3.0 and TLS first and only match SSL 2.0 hellos when flag to support it is set.

2016-11-02Add ECC curve selection order config in TLS serverFred Hebert
As per RFC 4492 Sec 5.1, the preferred order of selection of named curves is based on client preferences. Currently, the SSL application only picks entries according to the absolute order of entries as tracked in a hardcoded list in code. This patch changes things so that the client-specified order is preferred. It also allows a mode where the server can be configured to override the client's preferred order with its own, although the chosen ECC must still be within both lists. The configuration is done through the following options: - `eccs`, shared by clients and servers alike, allows the specification of the supported named curves, in their preferred order, and may eventually support more values for explicit primes and so on. - `honor_ecc_order`, a server-only option, is similar to `honor_cipher_order` and will, by default let the server pick the client-preferred ECC, and otherwise pick the server-preferred one. The default value for `eccs` is the same as before, although the server-chosen ECC now defaults to the client rather than previous choice. A function `ssl:eccs()` has been added that returns the highest supported ECCs for the library.

2016-05-31Improve SSL diagnosticsAlexey Lebedeff
There are a lot of cases where `ssl` application just returns unhelpful `handshake failure` or `internal error`. This patch tries to provide better diagnostics so operator can debug his SSL misconfiguration without doing hardcore erlang debugging. Here is an example escript that incorrectly uses server certificate as a client one: https://gist.github.com/binarin/35c34c2df7556bf04c8a878682ef3d67 With the patch it is properly reported as an error in "extended key usage".
2016-05-10ssl: ordsets:intersection/2 did not give the expected resultIngela Anderton Andin
Turns out we can not count on the "hashsigns" sent by the client and the supported "hashigns" sets to have required properties of ordsets.
2016-04-29ssl: Correct guard expressionIngela Anderton Andin
The guard should check that the TLS version is at least TLS-1.2.
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.
