Wladimir J. van der Laan	f4d1fc259b	wallet: Get rid of LockObject and UnlockObject calls in key.h ... Replace these with vectors allocated from the secure allocator. This avoids mlock syscall churn on stack pages, as well as makes it possible to get rid of these functions. Please review this commit and the previous one carefully that no `sizeof(vectortype)` remains in the memcpys and memcmps usage (ick!), and `.data()` or `&vec[x]` is used as appropriate instead of &vec.	8 years ago

Pieter Wuille	a56054be65	Update key.cpp to use new libsecp256k1 ... libsecp256k1's API changed, so update key.cpp to use it. Libsecp256k1 now has explicit context objects, which makes it completely thread-safe. In turn, keep an explicit context object in key.cpp, which is explicitly initialized destroyed. This is not really pretty now, but it's more efficient than the static initialized object in key.cpp (which made for example bitcoin-tx slow, as for most of its calls, libsecp256k1 wasn't actually needed). This also brings in the new blinding support in libsecp256k1. By passing in a random seed, temporary variables during the elliptic curve computations are altered, in such a way that if an attacker does not know the blind, observing the internal operations leaks less information about the keys used. This was implemented by Greg Maxwell.	10 years ago

Cory Fields	16a58a8644	keys: remove libsecp256k1 verification until it's actually supported ... This was added a while ago for testing purposes, but was never intended to be used. Remove it until upstream libsecp256k1 decides that verification is stable/ready.	10 years ago

Andrew Poelstra	4a09e1df51	key.cpp: fail with a friendlier message on missing ssl EC support ... Previously if bitcoind is linked with an OpenSSL which is compiled without EC support, this is seen as an assertion failure "pKey != NULL" at key.cpp:134, which occurs after several seconds. It is an esoteric piece of knowledge to interpret this as "oops, I linked with the wrong OpenSSL", and because of the delay it may not even be noticed. The new output is : OpenSSL appears to lack support for elliptic curve cryptography. For more information, visit https://en.bitcoin.it/wiki/OpenSSL_and_EC_Libraries : Initialization sanity check failed. Bitcoin Core is shutting down. which occurs immediately after attempted startup. This also blocks in an InitSanityCheck() function which currently only checks for EC support but should eventually do more. See #4081.	11 years ago

Pieter Wuille	6fd7ef2bbf	Also switch the (unused) verification code to low-s instead of even-s. ... a81cd968 introduced a malleability breaker for signatures (using an even value for S). In e0e14e43 this was changed to the lower of two potential values, rather than the even one. Only the signing code was changed though, the (for now unused) verification code wasn't adapted.	11 years ago
Gregory Maxwell	9b59e3bda8	Sanitize assert usage and refuse to compile with NDEBUG. ... There were quite a few places where assert() was used with side effects, making operation with NDEBUG non-functional. This commit fixes all the cases I know about, but also adds an #error on NDEBUG because the code is untested without assertions and may still have vulnerabilities if used without assert.	11 years ago
Brandon Dahler	51ed9ec971	Cleanup code using forward declarations. ... Use misc methods of avoiding unnecesary header includes. Replace int typedefs with int##_t from stdint.h. Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h. Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.	11 years ago
