* Correctly calculate the key block length when used with export ciphers.jsing2014-06-131-17/+24
| | | | While here, use meaningful variable names and simplify the calculation.
* Remove deprecated RFC2292 ancillary data convenience functions.chrisz2014-06-132-488/+2

* The export_key/export_iv variables are only used in the is_export case.jsing2014-06-131-7/+10
| | | | Also use c rather than &c[0].
* Rename a bunch of variables in ssl3_change_cipher_state() for readability.jsing2014-06-131-38/+40
| | | | This also brings it inline with tls1_change_cipher_state_cipher().
* Add ChaCha20-Poly1305 based ciphersuites.jsing2014-06-1310-14/+162
| | | | | | Based on Adam Langley's chromium patches. Tested by and ok sthen@

* Add support for handling SSL_CIPHER_ALGORITHM2_AEAD ciphers, which arejsing2014-06-138-66/+498
| | | | | | | | | | | | | those that use EVP_AEAD instead ov EVP_CIPHER. This means being able to change cipher state with an EVP_AEAD and being able to encrypt/decrypt TLS using the EVP_AEAD. This has no change on existing non-SSL_CIPHER_ALGORITHM2_AEAD ciphers. Based on Adam Langley's chromium patches. Rides the recent libssl bump. Tested by sthen@
* Add an SSL_AEAD_CTX to enable the use of EVP_AEAD with an SSL cipher.jsing2014-06-138-8/+98
| | | | | | | | | Read and write contexts are also added to the SSL_CTX, along with supporting code. Based on Adam Langley's chromium diffs. Rides the recent SSL library bump.
* Remove support for the `opaque PRF input' extension, which draft has expiredmiod2014-06-1323-668/+29
| | | | | | | | 7 years ago and never made it into an RFC. That code wasn't compiled in anyway unless one would define the actual on-the-wire extension id bytes; crank libssl major. With help and enlightenment from Brendan MacDonell.

* Abandon the auto-ENGINE /dev/crypto interface. VIA 3des cbc receivesderaadt2014-06-109-2738/+4
| | | | | | | | | | | | | collateral damage. The syncronous nature of this mechanism has hampered performance for symmetric crypto relative to brute-force cpu. The assymetric crypto support never really materialized in drivers. So abandon the complexity. ok tedu beck mikeb some disagrement from djm but if he wants to test /dev/crypto ciphers he should do it without this this gigantic API in the way

* In tls1_cert_verify_mac(), check the return value of EVP_MD_CTX_copy_ex()jsing2014-06-102-6/+10
| | | | | | | | | to avoid a possible NULL function call on ctx.final(). None of the callers currently check the return value of calls to cert_verify_mac(), however the function already returns 0 in another case and the MAC comparison will later fail. Issue reported by David Ramos.

* Avoid potential NULL pointer function calls in n_ssl3_mac() by checkingjsing2014-06-101-2/+4
| | | | | | | | | | the return value of EVP_MD_CTX_copy_ex(). If the copy fails early then EVP_DigestUpdate() will invoke md_ctx.update(), which will be a NULL function pointer. Analysis and patch from David Ramos. ok deraadt@
* Multiple fixes for ssl3_digest_cached_records() - if EVP_MD_CTX_create()jsing2014-06-101-8/+12
| | | | | | | | | fails, the NULL check will add an error but it does not abort. This will result in EVP_DigestInit_ex() being called with a NULL context. Also ensure that we check the return values from EVP_DigestInit_ex() and EVP_DigestUpdate(). ok deraadt@ miod@
* Ensure ssl3_final_finish_mac() returns failure if either the MD5 or SHA1jsing2014-06-101-5/+10
| | | | | | | | | handshake MAC calculation fails. Currently, the result from both ssl3_handshake_mac() calls is added together. This means that unless both MD5 and SHA1 fail, a positive value will be returned to the caller, indicating success rather than failure. ok deraadt@ miod@ sthen@
