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.
2016-02-18ssl: Remove DES ciphers from default configurationIngela Anderton Andin
DES is not considered secure. Also correct 'Server Name Indication' support description.

2015-06-10ssl: Add unassigned valuesIngela Anderton Andin
2015-06-08ssl: Do not crash on proprietary hash_sign algorithmsIngela Anderton Andin
TLS hash_sign algorithms may have proprietary values see http://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml We should add callbacks to let applications handle them. But for now we do not want to crash if they are present and let other algorithms be negotiated.

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.

2013-10-14ssl: Honor TLS client ECC extensionIngela Anderton Andin
Also the server should only send ECC point formats extension not ECC curve extension.

2013-09-10ssl: DTLS record handlingIngela Anderton Andin
Also refactor so that TLS and DTLS can have common functions when possible.

2013-03-28SSL: enable hash_size values for sha224, sha384 and sha512Andreas Schultz
Some of the PSK and SRP ciphers default to sha384, this enables hash_size for that cipher. It also adds sha512 and sha224 to be prepared for further cipher enhancements.
2013-03-28SSL: add TLS-SRP (RFC 5054) cipher suitesAndreas Schultz
2013-03-28SSL: add TLS PSK (RFC 4279 and RFC 5487) cipher suitesAndreas Schultz
2013-03-13public_key & ssl: Add support for ISO oids 1.3.14.3.2.29 and 1.3.14.3.2.27Ingela Anderton Andin
Some certificates may use these OIDs instead of the ones defined by PKIX/PKCS standard. Refactor code so that all handling of the "duplicate" oids is done by public_key. Update algorithm information in documentation.

2012-08-22ssl: Use crypto:strong_rand_bytes if possibleIngela Anderton Andin
2012-08-22ssl: Add Signature Algorithms hello extension from TLS 1.2Andreas Schultz
This is also avoids triggering some bugs in OpenSSL.
2012-08-22ssl: IDEA cipher is deprecated by TLS 1.2Ingela Anderton Andin
As we did not yet support IDEA ciphers and they have now become deprecated we skip supporting them altogether.
2012-08-22ssl: Make signature handling version dependantAndreas Schultz
TLS 1.2 introduces changes on how signatures are calculate and encoded. This makes the signature handling version aware
2012-08-22ssl: Fix PRF logicIngela Anderton Andin
2012-08-22ssl: Add TLS 1.2 cipher suitesAndreas Schultz
2012-08-22ssl: make PRF function selectableAndreas Schultz
TLS 1.2 allows to negotiate the used PRF, additional the default PRF uses a different hash. This change make the PRF selectable and hardwires the PRF for TLS < 1.2
2012-08-22ssl: Add TLS 1.2 block cipher IV handlingAndreas Schultz
2012-08-22ssl: Consider TLS version when building cipher blocksAndreas Schultz
With TLS 1.2 the handling of the IV in cipher blocks changed. This prepares ssl_cipher:cipher/5 for that change by passing the TLS version into it and allowing generic_block_cipher_from_bin/4 to overload the IV.

2011-12-05Fix typos in ssl_cipher.erlTuncer Ayaz
2011-10-24fix handling of block_decipher/5 failureAndreas Schultz
A wrong decryption key would cause a badmatch in generic_block_cipher_from_bin/2. The try in block_decipher/5 was probably intendend to deal with that, but was misplace for this. Additionaly, generating a failure alert erly, without computing the record MAC, creates vector for a timing attack on CBC padding (for details check TLS 1.2 RFC 5246, Sect. 6.2.3.2.). This attach vector and the counter meassure applies to all SSL/TLS versions. As a counter messure, compute the MAC even when decryption or padding checks fail. A invalid padding will force a MAC failure by intentionaly invalidating the content.
