2018-10-19ssl: Refactor AEAD ciphersIngela Anderton Andin
TLS-1.3 needs to handle AEAD inputs diffrently than previous versions. Refactor code to facilitate TLS-1.3 additions. Change CHACHA20_POLY1305 NONCE to match RFC 7905. This will be important later when we fix interop with TLS compatible crypto invocation.
2018-09-07ssl: Fix cipher suite handlingPéter Dimitrov
Implementations of TLS 1.3 which choose to support prior versions of TLS SHOULD support TLS 1.2. That is, a TLS 1.3 ClientHello shall advertise support for TLS 1.2 ciphers in order to be able to connect to TLS 1.2 servers. This commit changes the list of the advertised cipher suites to include old TLS 1.2 ciphers. Change-Id: Iaece3ac4b66a59dfbe97068b682d6010d74522b8

2018-09-04ssl: Initial cipher suites adoption for TLS-1.3Ingela Anderton Andin
This commit filters out cipher suites not to be used in TLS-1.3 We still need to add new cipher suites for TLS-1.3 and possible add new information to the suite data structure.

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.

2018-08-07ssl: Make sure that a correct cipher suite is selectedIngela Anderton Andin
The keyexchange ECDHE-RSA requires an RSA-keyed server cert (corresponding for ECDHE-ECDSA), the code did not assert this resulting in that a incorrect cipher suite could be selected. Alas test code was also wrong hiding the error.
2018-07-19ssl: Add experimental version 'tlsv1.3'Péter Dimitrov
- Add 'tlsv1.3' to the available versions. It can be used to trigger experimental behavior while implementing TLS 1.3. - Add dummy clauses for handling version {3,4} of TLS. - Update ssl_logger to handle unknown versions of TLS. Change-Id: I564ffa47dca18b59f0dc16c9809dfd7adaf2d333

2018-05-15ssl: Correct key_usage checkIngela Anderton Andin
The Key Usage extension is described in section 4.2.1.3 of X.509, with the following possible flags: KeyUsage ::= BIT STRING { digitalSignature (0), nonRepudiation (1), -- recent editions of X.509 have -- renamed this bit to contentCommitment keyEncipherment (2), dataEncipherment (3), keyAgreement (4), keyCertSign (5), cRLSign (6), encipherOnly (7), decipherOnly (8) } In SSL/TLS, when the server certificate contains a RSA key, then: either a DHE or ECDHE cipher suite is used, in which case the RSA key is used for a signature (see section 7.4.3 of RFC 5246: the "Server Key Exchange" message); this exercises the digitalSignature key usage; or "plain RSA" is used, with a random value (the 48-byte pre-master secret) being encrypted by the client with the server's public key (see section 7.4.7.1 of RFC 5246); this is right in the definition of the keyEncipherment key usage flag. dataEncipherment does not apply, because what is encrypted is not directly meaningful data, but a value which is mostly generated randomly and used to derive symmetric keys. keyAgreement does not apply either, because that one is for key agreement algorithms which are not a case of asymmetric encryption (e.g. Diffie-Hellman). The keyAgreement usage flag would appear in a certificate which contains a DH key, not a RSA key. nonRepudiation is not used, because whatever is signed as part of a SSL/TLS key exchange cannot be used as proof for a third party (there is nothing in a SSL/TLS tunnel that the client could record and then use to convince a judge when tring to sue the server itself; the data which is exchanged within the tunnel is not signed by the server). When a ECDSA key is used then "keyAgreement" flag is needed for beeing ECDH "capable" (as opposed to ephemeral ECDHE)
2018-04-30ssl: Avoid hardcoding of cipher suites and fix ECDH suite handlingIngela Anderton Andin
ECDH suite handling did not use the EC parameters form the certs as expected.

2018-02-07ssl: Make sure anonymous suites are handled separatelyIngela Anderton Andin
Preferably customized cipher suites will be based on the default value. But all may be used as base and hence it will be good to handle anonymous suites separately as they are intended for testing purposes.
2018-02-05ssl: Uses aead as mac value in AEAD cipher suitesIngela Anderton Andin
Authenticated encryption (AE) and authenticated encryption with associated data (AEAD, variant of AE) is a form of encryption which simultaneously provides confidentiality, integrity, and authenticity assurances on the data. This is more logical value then null that was used, this happened to work as the AEAD property was derived form other data, but it is confusing!
