STL or Qt containers?
...at e.g. QVector uses int as its index, thus limiting 31-bit sizes (even on 64-bit systems). Moreover, it can't even store INT_MAX elements of size larger than 1 byte. E.g. the largest .size() I could have of QVector<float> on x86_64 Linux gcc was 536870907 elements (2²⁹-5), while std::vecto...

About SHA-1 cost:
The elementary cost of SHA-1 is about hashing a 64-byte block. That's how SHA-1 works: data is padded, then split into 64-byte blocks. The cost of processing a single block is about 500 clock cycles on an Intel Core2 system, and that's for a single core. MD5 and MD4 are fa...
