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.

* 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.
2015-03-17ssl: 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+.
2015-03-11ssl: Dialyzer fixesIngela Anderton Andin
2014-04-23ssl: Refactor so that there is only one source for the default hashsign valuesIngela Anderton Andin
Also fix DTLS call to supply its corresponding TLS version
2014-04-23ssl: always pass negotiated version when selecting hashsignDanil Zagoskin
Negotiated version is now always passed to ssl_handshake:select_hashsign because ssl_handshake:select_cert_hashsign has different rsa defaults on tlsv1.2 and older versions.
2014-03-25ssl: Avoid dialyzer warnings in dtls codeIngela Anderton Andin
Even if DTLS is not finished, e.i. not runnable yet we want to phase in the code together with refactoring of TLS code, but without introducing warnings in the release.

2013-12-02ssl: Refactor connetion handlingIngela Anderton Andin
2013-12-02ssl: Refactor connection and handshake handlingIngela Anderton Andin
2013-09-10ssl: Refactor TLS/DTLS record handlingIngela Anderton Andin
2013-09-10ssl: Refactor to provide common handshake functions for TLS/DTLSIngela Anderton Andin
Common functions will be located in ssl_handshake.erl while specific functions will be located in tls_handshake.erl and dtls_handshake.erl
2013-06-04ssl: Structural perarparation to support DTLSIngela Anderton Andin
Also phase in tls module as main API instead of ssl. To make API clearer. As TLS is the new protocol name. Maybe keep some API functions in ssl
