* GOST crypto algorithms (well, most of them), ported from the removed GOSTmiod2014-11-0975-31/+13110
| | | | | | | | | | | | engine to regular EVP citizens, contributed by Dmitry Eremin-Solenikov; libcrypto bits only for now. This is a verbatim import of Dmitry's work, and does not compile in this state; the forthcoming commits will address these issues. None of the GOST code is enabled in libcrypto yet, for it still gets compiled with OPENSSL_NO_GOST defined. However, the public header gost.h will be installed.
* Introduce EVP_MD_CTX_ctrl(), to allow for fine control of a given digest.miod2014-11-094-4/+52
| | | | | | | | | This functionality was already available (and optional), and used in the bowels of the ASN.1 code. This exposes it as a public interface, which will be used by the upcoming GOST code. Crank libcrypto minor version. From Dmitry Eremin-Solenikov.

* Add hooks to override native arc4random_buf on FreeBSD.bcook2014-11-034-0/+298
| | | | | | | | | | | | | | | | The FreeBSD-native arc4random_buf implementation falls back to weak sources of entropy if the sysctl fails. Remove these dangerous fallbacks by overriding locally. Unfortunately, pthread_atfork() is also broken on FreeBSD (at least 9 and 10) if a program does not link to -lthr. Callbacks registered with pthread_atfork() simply fail silently. So, it is not always possible to detect a PID wraparound. I wish we could do better. This improves arc4random_buf's safety compared to the native FreeBSD implementation. Tested on FreeBSD 9 and 10.

* Remove now unused remnants from public structs.jsing2014-10-314-14/+4
|
* Add support for automatic DH ephemeral keys.jsing2014-10-3112-44/+194
| | | | | | | This allows an SSL server to enable DHE ciphers with a single setting, which results in an DH key being generated based on the server key length. Partly based on OpenSSL.
* Remove support for ephemeral/temporary RSA private keys.jsing2014-10-3114-474/+88
| | | | | | | | | The only use for these is via SSL_OP_EPHEMERAL_RSA (which is effectively a standards violation) and for RSA sign-only, should only be possible if you are using an export cipher and have an RSA private key that is more than 512 bits in size (however we no longer support export ciphers). ok bcook@ miod@
