* kennethlakin/tls-use-negotiated-prf/PR-1042/OTP-13546: ssl: Use cipher suite's PRF in prf/5
2016-05-05ssl: Add reinitialization of handshake data lost in gen_statem refactorizationIngela Anderton Andin
2016-05-05ssl: Use cipher suite's PRF in prf/5Kenneth Lakin
Use the negotiated cipher suite's PRF algorithm in calls to ssl:prf/5, rather than a hard-coded one. For TLS 1.0 the PRF algorithm was hard-coded to MD5/SHA1. This was correct 100% of the time. For TLS 1.1 and 1.2 the PRF algorithm was hard-coded to SHA256. This was correct only some of the time for TLS 1.2 and none of the time for TLS 1.1. Because the TLS handshake code calls tls_v1:prf/5 through another path, the handshaking process used the negotiated PRF and did not encounter this bug. A new test (prf) has been added to ssl_basic_SUITE to guard against future breakage.
2016-05-03ssl: Use gen_statem instead of gen_fsmIngela Anderton Andin
Also reduce timing issues in tests
2016-04-25ssl: Remove use of crypto:rand_bytes/1Ingela Anderton Andin
ssl already used crypto:strong_rand_bytes/1 for most operations as its use cases are mostly cryptographical. Now crypto:strong_rand_bytes/1 will be used everywhere. However crypto:rand_bytes/1 was used as fallback if crypto:strong_rand_bytes/1 throws low_entropy, this will no longer be the case. This is a potential incompatibility. The fallback was introduced a long time ago for interoperability reasons. Now days this should not be a problem, and if it is, the security compromise is not acceptable anyway.

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.
2015-12-03ssl: Measure elapsed time with erlang:monotonic_timeIngela Anderton Andin
2015-10-28Avoid crash for SSL connections with nonexistent keyfileMagnus Henoch
Starting an SSL connection with a nonexistent keyfile will obviously return an error: > ssl:connect("www.google.com", 443, [{keyfile, "nonexistent"}]). {error,{options,{keyfile,"nonexistent",{error,enoent}}}} But it also generates an error report with the following backtrace: ** Reason for termination = ** {badarg,[{ets,select_delete, [undefined,[{{{undefined,'_','_'},'_'},[],[true]}]], []}, {ets,match_delete,2,[{file,"ets.erl"},{line,700}]}, {ssl_pkix_db,remove_certs,2,[{file,"ssl_pkix_db.erl"},{line,243}]}, {ssl_connection,terminate,3, [{file,"ssl_connection.erl"},{line,941}]}, {tls_connection,terminate,3, [{file,"tls_connection.erl"},{line,335}]}, {gen_fsm,terminate,7,[{file,"gen_fsm.erl"},{line,610}]}, {gen_fsm,handle_msg,7,[{file,"gen_fsm.erl"},{line,532}]}, {proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,240}]}]} This happens because the ssl_connection process receives its cert_db while handling the {start, Timeout} message, but if the handshake fails, the cert_db will never be inserted into the state data, and the terminate function will use 'undefined' as an ETS table name. Avoid this by checking for 'undefined' in the handle_trusted_certs_db function.
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.

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.
2015-05-12ssl: add SNI server supportQijiang Fan
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+.

2014-12-01ssl: Change code to reflect that state data may be secretIngela Anderton Andin
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."

2014-04-23ssl: 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.

2014-01-14ssl: fix elliptic curve selection in server modeAndreas Schultz
The server code erroneously took the list of curves supported by the client from it's own hello extension, effectively breaking curve selection all together. Also the default fallback secp256k1 curve is not supported by all clients. secp256r1 is recommended as part of the NIST Suite B cryptographic suites. The chances are much better that all clients support it, so use that as fallback.

2013-05-24ssl: Remove unused `srp_parameters` type specKlaus Trainer
As the file 'lib/ssl/src/ssl_srp_primes.hrl' only contains a specification of a `srp_parameters` type that isn't exported and also isn't referenced anywhere (neither in the code nor in the documentation), the type specification (and hence the file as well) can be removed.
