* Reject excessively large primes in DH key generation. Problem reportedsthen2018-06-121-1/+6
| | | | | | | | | | | by Guido Vranken to OpenSSL (https://github.com/openssl/openssl/pull/6457) and based on his diff. suggestions from tb@, ok tb@ jsing@ "During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack."
* Send the function codes from the error functions to the bit bucket,beck2017-01-291-6/+6

* Make explicit _ct and _nonct versions of bn_mod_exp funcitons thatbeck2017-01-211-2/+4
| | | | | | | | | | | | matter for constant time, and make the public interface only used external to the library. This moves us to a model where the important things are constant time versions unless you ask for them not to be, rather than the opposite. I'll continue with this method by method. Add regress tests for same. ok jsing@

* Remove flags for disabling constant-time operations.bcook2016-06-301-26/+11
| | | | | | | | This removes support for DSA_FLAG_NO_EXP_CONSTTIME, DH_FLAG_NO_EXP_CONSTTIME, and RSA_FLAG_NO_CONSTTIME flags, making all of these operations unconditionally constant-time. Based on the original patch by César Pereid. ok beck@
* BN_CTX_get() can fail - consistently check its return value.jsing2015-02-091-2/+3
| | | | | | | | | | | | | | | There are currently cases where the return from each call is checked, the return from only the last call is checked and cases where it is not checked at all (including code in bn, ec and engine). Checking the last return value is valid as once the function fails it will continue to return NULL. However, in order to be consistent check each call with the same idiom. This makes it easy to verify. Note there are still a handful of cases that do not follow the idiom - these will be handled separately. ok beck@ doug@

functionality for shared libs. Note that routines such as sslv2_init and friends that use RSA will not work due to lack of RSA in this library. Needs documentation and help from ports for easy upgrade to full functionality where legally possible.
