| | | | | | | | premaster secret, so name it accordingly. Also, remove bogus assignment of master_key_length - the correct value is assigned when the master_key is set. ok beck@ doug@

| | | | | | | ngroup and the following EC_KEY_set_group() fails, ngroup will not be freed. Avoid this by freeing on return. ok millert@
* Avoid signed vs unsigned warnings from clang by adding two casts,jsing2016-12-031-2/+2
| | | | | | slightly rewriting some code and changing the type of an array. ok bcook@ doug@

* Convert ssl3_get_server_kex_ecdhe() to CBS, simplifying tls1_check_curve()jsing2016-11-051-42/+33
| | | | | | | in the process. This also fixes a long standing bug where tls1_ec_curve_id2nid() is called with only one byte of the curve ID. ok beck@ miod@
* Rename ssl3_get_key_exchange() to ssl3_get_server_key_exchange(), sincejsing2016-11-041-3/+3
| | | | | | that's what it really is. ok miod@
* Tidy up the usage of peer_ecdh_tmp, following the fixed ECDH removal.jsing2016-11-041-13/+5

* Convert ssl3_get_server_kex_dhe() to CBS.jsing2016-11-041-42/+19
| | | | ok beck@
* Split ssl3_get_key_exchange() into separate functions for DHE/ECDHE.jsing2016-11-031-205/+256
| | | | ok beck@ (who was struggling to keep lunch down while reviewing the diff)
* Remove support for fixed ECDH cipher suites - these is not widely supportedjsing2016-10-191-14/+5
| | | | | | | | | and more importantly they do not provide PFS (if you want to use ECDH, use ECDHE instead). With input from guenther@. ok deraadt@ guenther@
* Merge a memleak fix from BoringSSL 6b6e0b2:mmcc2016-03-271-1/+3
| | | | | | https://boringssl.googlesource.com/boringssl/+/6b6e0b20893e2be0e68af605a60ffa2cbb0ffa64%5E!/#F0 ok millert@, beck@

* Stop generating private keys in a network buffer.jsing2015-09-131-29/+29
| | | | | | | | | | The current client key exchange code generates DH and ECDH keys into the same buffer that we use to send data to the network - stop doing this and malloc() a new buffer, which we explicit_bzero() and free() on return. This also benefits from ASLR and means that the keys are no longer generated in a well known location. ok beck@
* Use ECDH_size() instead of rolling our own.jsing2015-09-131-6/+5
| | | | ok beck@
* Split ssl3_send_client_key_exchange() (387 lines of code) into fivejsing2015-09-121-327/+351
| | | | | | | | | functions. The original was written as a huge if/else if chain - split out the handling for each key exchange type. This allows us to reduce two levels of indentation, make the code far more readable and have single return paths so that we can simplify clean up. ok beck@
* explicit_bzero() the GOST premaster secret.jsing2015-09-121-2/+7
| | | | ok miod@
* Remove most of the SSLv3 version checks and a few TLS v1.0.doug2015-09-121-39/+21
| | | | | | | We can now assume >= TLS v1.0 since SSL2_VERSION, SSL3_VERSION and DTLS1_BAD_VER support was removed. "reads ok" miod@
* Use explicit_bzero() instead of memset() when clearing private keys.jsing2015-09-121-3/+4

* Replace dtls1_client_hello() with ssl3_client_hello() - both are basicallyjsing2015-09-021-5/+22
| | | | | | | | | | | the same code, with two slight differences for DTLS handling. Also, make use of send_cookie to determine if the client random needs to be preserved, rather than testing if it is zeroed (hopefully your random number generator never returned all zeros, since the existing code would break). Inspired by BoringSSL. ok doug@

* Remove SSLv3 support from LibreSSL.doug2015-08-271-15/+1
| | | | | | | | | | This is the first wave of SSLv3 removal which removes the main SSLv3 functions. Future commits will remove the rest of the SSLv3 support. Discussed the plan at c2k15. Input from jsing@, beck@, miod@, bcook@, sthen@, naddy@, and deraadt@. ok jsing@, beck@
* Add linker warnings in case SSLv3_{,client,server}_method are referenced.miod2015-07-291-1/+7
| | | | | | | Use of this symbols proves the existence of a code path willingly using SSLv3, even with OPENSSL_NO_SSL3 being defined, which hints that it needs fixing. Discussed with the LibreSSL cabal during c2k15; ok deraadt@
