* Add ability for application to control which TLS extensions are usedJack Lloyd2018-01-271-0/+7
| | | | GH #1186
* Add supported groups TLS extension (RFC 7919)René Korthaus2017-10-171-6/+14

* Apply final annotations to the library alsoJack Lloyd2017-09-221-1/+1
| | | | | Done by a perl script which converted all classes to final, followed by selective reversion where it caused compilation failures.
* More include header cleanupsJack Lloyd2017-09-211-1/+0
|
* Change header guard format to BOTAN_FOO_H_Jack Lloyd2017-09-201-2/+2
| | | | | | ISO C++ reserves names with double underscores in them Closes #512
* Add API stability annotations.Jack Lloyd2017-09-191-1/+1
| | | | | Defined in build.h, all equal to BOTAN_DLL so ties into existing system for exporting symbols.
* Content:Tomasz Frydrych2017-04-031-8/+8
| | | | | | | | | * fixes for deprecated constructions in c++11 and later (explicit rule of 3/5 or implicit rule of 0 and other violations) * `default` specifier instead of `{}` in some places(probably all) * removal of unreachable code (for example `return` after `throw`) * removal of compilation unit only visible, but not used functions * fix for `throw()` specifier - used instead `BOTAN_NOEXCEPT` * removed not needed semicolons
* Convert to using standard uintN_t integer typesJack Lloyd2016-12-181-46/+46
| | | | | | Renames a couple of functions for somewhat better name consistency, eg make_u32bit becomes make_uint32. The old typedefs remain for now since probably lots of application code uses them.
* Add OCSP stapling support to TLS clientJack Lloyd2016-11-261-4/+32
|
* Fix incompatability with (some) common TLS stackJack Lloyd2016-11-161-1/+2
| | | | | | | | Several sites including oracle.com seem to send extension 11 (point format) even if we (the client) did not send it. Then the handshake fails. To workaround this problem, simply always send this extension as the client, instead of only sending it if we wished to support compressed points.
* Support encoding of supported point formats extensionRené Korthaus2016-10-031-0/+32

* New TLS positive and negative tests.Juraj Somorovsky2016-09-301-1/+1
| | | | | | | | | | | | | | | | | | | TLS message parsing: - CertificateVerify - HelloVerify - ClientHello (with extensions) - ServerHello (with extensions) - NewSessionTicket - Alert TLS message processing: - HelloVerify TLS Policy tests Unit tests with TLS client authentication Added test_throws method that checks the correct exception message.
* TLS Server should respect client signature_algorithms. Stricter TLS hello ↵Jack Lloyd2016-09-211-4/+5
| | | | | | | | | | | | | | | | | | | | decoding. If the client sent a signature_algorithms extension, we should negotiate a ciphersuite in the shared union of the ciphersuite list and the extension, instead of ignoring it. Found by Juraj Somorovsky GH #619 The TLS v1.2 spec says that clients should only send the signature_algorithms extension in a hello for that version. Enforce that when decoding client hellos to prevent this extension from confusing a v1.0 negotiation. TLS v1.2 spec says ANON signature type is prohibited in the signature_algorithms extension in the client hello. Prohibit it. Reorder the TLS extensions in the client hello so there is no chance an empty extension is the last extension in the list. Some implementations apparently reject such hellos, even (perhaps especially) when they do not recognize the extension, this bug was mentioned on the ietf-tls mailing list a while back.
* Merge master into this branch, resolving conflicts with #457/#576Jack Lloyd2016-08-311-1/+1

| * Reduction of code complexity in TLS classes.Matthias Gierlings2016-06-191-1/+1
| | | | | | | | | | | | | | -reduced number of parameters in various methods -reduced cyclomatic complexity (McCabe-Metric) -removed "TLSEXT_HEARTBEAT_SUPPORT" from tls_extensions.h (leftover from heartbeat extension removal?)
* | Address some issues with PR 492Jack Lloyd2016-08-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds copyright notices for Juraj Somorovsky and Christian Mainka of Hackmanit for the changes in 7c7fcecbe6a and 6d327f879c Add Policy::check_peer_key_acceptable which lets the app set an arbitrary callback for examining keys - both the end entity signature keys from certificates and the peer PFS public keys. Default impl checks that the algorithm size matches the min keylength. This centralizes this logic and lets the application do interesting things. Adds a policy for ECDSA group size checks. Increases default policy minimums to 2048 RSA and 256 ECC. (Maybe I'm an optimist after all.)
* | Encrypt-then-MAC extension (RFC 7366)Juraj Somorovsky2016-05-111-0/+21
|/ | | | | | Introduced a countermeasure against the logjam attack Short TLS records (AES-CBC) now return BAD_RECORD_MAC Fixed a compatibility problem with OpenSSL and TLS 1.0 (BEAST countermeasure)

* Make SRP6 support optional in TLSJack Lloyd2016-02-071-0/+2
| | | | | | | | Remove SRP_SHA from the default policy, since normal applications do not need it. Removes nullptr initializers of unique_ptrs in the Server_Key_Exchange constructor, that's the default unique_ptr already.
* Remove support for the TLS min fragment length extension.Jack Lloyd2016-02-071-33/+1
|
* Remove TLS heartbeat support.Jack Lloyd2016-02-071-26/+0
| | | | | The signature of the alert callback remains unchanged to avoid breaking applications, though now the buffer parameter is never set.
* Add final attribute to many classesJack Lloyd2016-01-101-11/+11
| | | | | | | In some cases this can offer better optimization, via devirtualization. And it lets the user know the class is not intended for derivation. Some discussion in GH #402

* Add DTLS-SRTP key establishment from RFC 5764 (required for WebRTC).lloyd2015-01-041-0/+27
| | | | | | | | | | | | | | Github issue 27. Refactor server hello handling to make it easier to handle other extensions. The manual specified that 224 bit NIST primes were disabled by default for TLS but they were not. Additionaly disable the 256k1 curve and reorder the remaining curves by size. Rewrite the max fragment length extension code to roughly what an ideal compiler would have turned the original code into, using a switch instead of a lookup into a small constant std::map.
