Janek Bevendorff 13eb1c0bbd Improve resilience against memory attacks ... To reduce residual fragments of secret data in memory after deallocation, this patch replaces the global delete operator with a version that zeros out previously allocated memory. It makes use of the new C++14 sized deallocation, but provides an unsized fallback with platform-specific size deductions. This change is only a minor mitigation and cannot protect against buffer reallocations by the operating system or non-C++ libraries. Thus, we still cannot guarantee all memory to be wiped after free. As a further improvement, this patch uses libgcrypt and libsodium to write long-lived master key component hashes into a secure memory area and wipe it afterwards. The patch also fixes compiler flags not being set properly on macOS.		2019-04-21 09:39:28 -04:00
