2017-11-22ssl: Countermeasurements for Bleichenbacher attackIngela Anderton Andin
Back ported for security reasons. Remove DTLS changes as DTLS is not at all working in OTP 18.

2016-06-09ssl: 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.
2016-06-09ssl:recv timeout() can be 0Joe DeVivo
gen_tcp:recv allows this, and if you're doing something like Transport:recv(Socket, 0, 0), TCP will work and SSL will exit with function_clause There were other cases of this throughout the module. This PR cleans them all up.
2016-06-09ssl: 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.

2016-04-22ssl: Corrections to cipher suite handlingIngela Anderton Andin
It was not possible to mix ssl 3 and 4 tuple cipher suites in the ciphers option. Some ssl_cipher:suite/1 clauses wrongly returned 3-tuples that should have been 4 tuples
2016-04-06ssl: Prepare for releaseIngela Anderton Andin
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.

2016-02-23ssl: Modernize utility functionIngela Anderton Andin
Use application:ensure_all_started/2 instead of hard coding dependencies
2016-02-22Fix ssl exampleMagnus Henoch
As recently discussed on the erlang-questions mailing list, this example fails to start the ssl application because ssl depends on asn1 nowadays. Let's future-proof this by using application:ensure_all_started/1.
2016-02-22ssl: Newer cipher suites now presented correctlyIngela Anderton Andin
Older SSL/TLS versions have cipher suites that look like {key_exchange(), cipher(), MAC::hash()} and the hash function used by the PRF (Pseudo Random function) is implicit and always the same for that protocol version. In TLS 1.2 a cipher suite is {key_exchange(), cipher(), MAC::hash(), PRF::hash()}. Internally a cipher suite is always a four tuple but for backwards compatibility older cipher suites will be presented as a three tuples, however new cipher suites should be presented as four tuples.
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.

2016-02-17Be suspicious of certificates without CRL DPsMagnus Henoch
Previously, if certificate revocation checking was turned on, and a certificate didn't contain a CRL Distribution Points extension, and there was no relevant CRL in the cache, then ssl_handshake:crl_check would accept the certificate even if the crl_check option was set to reject certificates for which the revocation status could not be determined. With this change, such certificates will only be accepted if the crl_check option was set to best_effort. The process for CRL validation is described in section 6.3 of RFC 5280. The text doesn't mention any special treatment to be given to certificates without distribution points: it just says "For each distribution point..." (section 6.3.3), which would leave the revocation status undetermined, unless there were "any available CRLs not specified in a distribution point but issued by the certificate issuer". Thus the result of this algorithm should be UNDETERMINED in this case, not UNREVOKED, and the crl_check option should govern how the implementation reacts to this result.
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.

2016-02-08ssl: verify cert signature against original cert binaryMatt Campbell
When searching for a certificate's issuer in the `CertDB`, verify the signature against the original DER certificate from the handshake instead of a re-encoding of the parsed certificate. This avoids false negatives due to differences between DER encoding implementations of OTP and other platforms.

2016-01-28Ensure testing ssl with supported ciphers onlyDániel Szoboszlay
There are two problematic areas: EC curve selection and interoperability tests with OpenSSL. The tests shouldn't assume any particular EC curve is available, but should always check the list of curves reported by tls_v1:ecc_curves/1. And during interoperability tests the tests shouldn't assume that any cipher suite supported by Erlang is also supported by OpenSSL. There are OpenSSL packages where the command line openssl tool only supports a subset of the ciphers available in libcrypto. The actual list of supported cipher suites thus shall be queried from OpenSSL.
2016-01-27Refactor ssl_crl_SUITE: extract crl_verify_error/6Magnus Henoch
Just like crl_verify_valid/5 checks for a positive result given certain options, crl_verify_error/6 checks for a negative result.

2016-01-26ssl: Only start a new session validator if the old one has finished its workIngela Anderton Andin
If the session table is big the validator may not have finshed before the validation interval is up, in this case we should not start a new validator adding to the cpu load.

Use erlang:unique_integer/1 instead of erlang:now/0 to generate a unique node name. Use rand:uniform/1 instead of random:uniform/1, so we don't need to generate a seed ourselves.
