* Remove support for fixed ECDH cipher suites - these is not widely supportedjsing2016-10-191-30/+2
| | | | | | | | | and more importantly they do not provide PFS (if you want to use ECDH, use ECDHE instead). With input from guenther@. ok deraadt@ guenther@
* Implement the IETF ChaCha20-Poly1305 cipher suites.jsing2016-04-281-6/+16
| | | | | | | | | Rename the existing ChaCha20-Poly1305 cipher suites with an "-OLD" suffix, effectively replaces the original Google implementation. We continue to support both the IETF and Google versions, however the existing names now refer to the ciphers from draft-ietf-tls-chacha20-poly1305-04. Feedback from doug@
* Rename EVP_aead_chacha20_poly1305() to EVP_aead_chacha20_poly1305_old()jsing2016-04-281-2/+2
| | | | | | | and replace with EVP_aead_chacha20_poly1305_ietf(). The IETF version will become the standard version. Discussed with many.

* If we have hardware acceleration for AES, prefer AES as a symmetric cipherjsing2015-09-131-7/+30
| | | | | | over CHACHA20. Otherwise, prefer CHACHA20 with AES second. ok beck@ miod@
* Provide a SSL_CIPHER_get_by_value() function that allows a cipher to bejsing2015-02-071-1/+19
| | | | | | | | | | | | | | retrieved via its cipher suite value. A corresponding SSL_CIPHER_by_value() function returns the cipher suite value for a given SSL_CIPHER. These functions should mean that software does not need to resort to put_cipher_by_char()/get_cipher_by_char() in order to locate a cipher. Begrudgingly also provide a SSL_CIPHER_get_by_id() function that locates a cipher via the internal cipher identifier. Unfortunately these have already been leaked outside the library via SSL_CIPHER_by_id() and the various SSL3_CK_* and TLS1_CK_* defines in the ssl3.h/tls1.h headers. ok beck@ miod@
* Add AEAD as a "MAC alias" so that it is possible to identify/select ciphersjsing2015-01-261-1/+5
| | | | | | | | that use AEAD instead of a MAC. This allows for TLSv1.2 AEAD ciphers (effectively the only ciphers that are still considered to be secure) to be selected using TLSv1.2+AEAD as a cipher string. ok bcook@ doug@ miod@
