* Merge GH #872 Add ability for TLS servers to prohibit renegotiationJack Lloyd2017-09-193-2/+16
|\
| * Fix logic of renegotiation checkJack Lloyd2017-02-203-4/+6
| | | | | | | | | | | | Turning the policy off broke the server entirely. Expose the new flag to Text_Policy
| * Add TLS::Policy::allow_client_initiated_renegotiationJack Lloyd2017-02-193-2/+14
| | | | | | | | Parallel of the server policy flag.
* | Use constant_time_compare instead of same_memJack Lloyd2017-09-162-3/+3
| | | | | | | | New name, same great operation
* | Correct TLS::Policy::latest_supported_versionJack Lloyd2017-09-041-2/+16
| | | | | | | | | | This would do the wrong thing if TLS v1.2 was disabled but v1.0/v1.1 allowed.
* | De-inline accessor functions in Client_Hello typeJack Lloyd2017-09-012-93/+130
| | | | | | | | | | This class is exposed but the extension types aren't, so calls to these functions from outside the library would not link.
* | Don't try enforcing the hash policy for PSK ciphersuitesJack Lloyd2017-09-011-1/+1
| | | | | | | | Since we don't end up signing anything in any case.
* | Enforce signature hash policy properlyJack Lloyd2017-08-314-17/+61
| | | | | | | | | | | | | | | | Previously if the client did not send signature_algorithms, or if it only included algos not in the policy, we would just fallback to the hardcoded SHA-1 default of TLS v1.2 Instead check the policy before accepting anything.
* | More MSVC warnings fixesJack Lloyd2017-08-312-6/+6
| |
* | Fix various MSVC warningsJack Lloyd2017-08-312-4/+7
| | | | | | | | Based on VC2017 output
* | Avoid false positive valgrind in TLS CBC decryptionJack Lloyd2017-08-291-2/+2
| | | | | | | | | | | | We poisoned the record before decrypting it, which caused failures with Camellia ciphersuites (or AES, on platforms that use T-tables). Instead poison it right after decrypting.
* | Add support for ECDHE_PSK AEAD ciphersuitesJack Lloyd2017-08-221-2/+6
| | | | | | | | From draft-ietf-tls-ecdhe-psk-aead-05, now with official codepoints.
* | Initialize member var in Certificate_Status_RequestJack Lloyd2017-08-031-1/+2
| | | | | | | | | | This var is only used when encoding so was never read from, but leaving it uninitialized is bad news. Flagged by Coverity.
* | Correct failure when renegotiating with old serverJack Lloyd2017-06-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When renegotiating the client checks that the server hasn't changed its mind about supporting the renegotiation extension (this is a likely indicator of an attack). However due to a typo the client was actually comparing the value in the client hello of the first handshake against the server hello in the renegotiation handshake. Since Botan always sends the renegotiation extension, this would cause the check to fail when renegotiating with an old server that doesn't support the renegotiation extension. Reported on mailing list by Falko Strenzke. Tested patch against OpenSSL 0.9.8k
* | Make it easier to customize Text_Policy when inheriting from itlouiz’2017-04-271-1/+1
| | | | | | | | | | | | This way, the library user can improve the class by adding missing functions or some other tweak they may find useful. Without any access to m_kv this is impossible.
* | Add some missing function overrides in TLS::Text_Policylouiz’2017-04-251-0/+12

* | Use 3 arg BOTAN_UNUSED in a codepath that is compiled oftenSimon Warta2017-04-171-3/+1
| | | | | | | | | | just to verify the implementation works fine across platforms and compilers
* | Content:Tomasz Frydrych2017-04-0314-68/+60
| | | | | | | | | | | | | | | | | | * 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
* | Remove "Dirty hack" for multiple defines in lex_me_harder()Simon Warta2017-04-024-4/+12

* Add static_cast in uint8_t vs enum comparison.Jack Lloyd2017-01-281-2/+2
| | | | Sun CC for whatever reason becomes very confused by this.
* Merge GH #814 Avoid negotiating CECPQ1 if x25519 ECC is disabledJack Lloyd2017-01-061-0/+10
|\
| * Avoid negotiating CECPQ1 if x25519 ECC is disabledJack Lloyd2017-01-051-0/+10
| |
* | Add tests for certificate status messageJack Lloyd2017-01-041-8/+8
|/ | | | | | | Currently untested by TLS crosstalk tests because it is not supported on the server side. Exposes the rest of TLS message types to application.
* Increase default TLS DH min to 2048 bits, and add BSI policy class.Jack Lloyd2016-12-302-2/+56
| | | | | Moves BSI policy file to test data dir where it can be compared with what the hardcoded class outputs.
* Add CECPQ1 OCB ciphersuitesJack Lloyd2016-12-301-1/+3
| | | | | | Clean up the ciphersuite generation script a bit. [ci skip]
* Prohibit SHA256/SHA384 ciphersuites in TLS 1.0/1.1 (GH #496)Jack Lloyd2016-12-281-3/+10
|
* Export tls_messages.h as a public headerRené Korthaus2016-12-2320-30/+43
| | | | | | | TLS::Callbacks::inspect_handshake_message() allows applications to inspect all handshake messages, but this requires access to the types in tls_messages.h. As a matter of fact, this also exports tls_extensions.h as a public header.
* Convert to using standard uintN_t integer typesJack Lloyd2016-12-1855-880/+881
| | | | | | 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.
* Disable TLS signature and finished message checks in fuzzer modeJack Lloyd2016-12-173-3/+23
| | | | | Also use a const time comparison for the finished message, though I don't see any real way of exploiting that timing channel.
* Fix bad deref when ciphersuite value is larger than largest known idJack Lloyd2016-12-051-1/+1
| | | | Reported by @neverhub in GH #758 found by libFuzzer
* Add TLS::Policy::require_cert_revocation_infoJack Lloyd2016-11-283-1/+14

* Merge GH #653 OCSP and X.509 path validation refactorJack Lloyd2016-11-259-86/+149
|\ | | | | | | | | | | Splits up path validation into several sub-functions for easier testing and creating customized validation code. Much improved OCSP handling and OCSP tests.
| * Add missing Doxygen param [ci skip]Jack Lloyd2016-11-251-0/+2

| * Add minimum_signature_strenght to Text_PolicyJack Lloyd2016-11-252-3/+9
| | | | | | | | Also (unrelated) enable CECPQ1 in Strict_Policy
| * Add TLS::Policy::minimum_signature_strengthJack Lloyd2016-11-256-5/+25
| | | | | | | | | | | | Changes TLS callback API for cert verify to accept Policy& Sets default signature strength to 110 to force RSA ~2048.
| * Address review comments from @cordneyJack Lloyd2016-11-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Primarily doc updates but also expose some more logic in PKIX namespace, overall_status and merge_revocation_status. This allows calling more or less all of the logic used by the monolitic x509_path_validate in any way needed by an application. Add Certificate_Store_In_Memory::add_crl variant taking shared_ptr Add optional Certificate_Store_In_Memory* pointer to check_crl_online, valid CRLs are saved there.
| * Add the documented function for OCSP timeoutsJack Lloyd2016-11-232-3/+10
| |
| * Move TLS cert verification callback from Credentials_Manager to TLS::CallbacksJack Lloyd2016-11-237-83/+110
| | | | | | | | | | | | It is the only function in C_M which is called on to process session-specific (and adversarially provided) inputs, rather than passively returning some credential which is typically not session specific.
* | Simplify TLS::Ciphersuite::cbc_ciphersuiteJack Lloyd2016-11-251-3/+1
| | | | | | | | With RC4 removed, anything that is not AEAD is CBC
* | Simplify TLS::Handshake_Hash::updateJack Lloyd2016-11-251-9/+5
|/ | | | The lambda here wasn't really required.
* TLS CBC functionality now exposed to the library developer. Useful for ↵Juraj Somorovsky2016-11-191-1/+1
| | | | | | direct TLS CBC testing. CLI TLS server now catches an exception if an invalid connection is received (Otherwise, the server always stopped working)
* Order default TLS ECC curve preferences by performanceJack Lloyd2016-11-191-4/+6
| | | | | | | | | | | | Moves x25519 to the front for best by-default side channel resistance, and orders remaining NIST/BP curves by performance rather than size. That means putting P-521 before P-384, since P-521 is much faster at least in Botan (due to much simpler modular reduction for P-521 prime), and Brainpools to the end due to being quite slow (no fast reductions). All of the supported curves seem strong enough, and if someone can break P-256 they can probably break P-384 as well so there doesn't seem much advantage in preferring slower curves by default.
* Add CECPQ1 TLS ciphersuitesJack Lloyd2016-11-176-14/+92
| | | | | | | | | | | | | Tested against BoringSSL (as client + server) and google.com (as client). Fix a stupid crashing bug in NewHope's BoringSSL mode. Remove unneeded error return from curve25519_donna - always returned 0. Default policy prefers ChaChaPoly1305 over GCM and CECPQ1 over ECDH/DH, which means the default no-extra-configuration ciphersuite (for Botan client speaking to Botan server) is a ciphersuite which is both implemented in constant time on all platforms and (hopefully) provides post quantum security. Good Things.
* Fix incompatability with (some) common TLS stackJack Lloyd2016-11-164-15/+26
| | | | | | | | 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.
* Add new TLS callback for when session is activatedJack Lloyd2016-11-162-0/+8
| | | | | | The current session established cb happens before the session is activated, so it is not possible to send application data in response to the connection being made.
* Pubkey cleanupsJack Lloyd2016-11-121-3/+1
| | | | | | | | | | Add Public_Key::key_length usable for policy checking (as in TLS::Policy::check_peer_key_acceptable) Remove Public_Key::max_input_bits because it didn't make much sense for most algorithms actually. Remove message_parts and message_part_size from PK_Ops
