It can still be a GOOD or recommended hash function. But a bad seed of 0 leading to collisions is considered a bug, a bad hash function. We test for internal secrets, if they will be multiplied with 0. This is also called "blinding multiplication". main.cpp lists some secrets for ...

针对您提供的错误信息“in function 'std::size_t boost::hash_value(const std::error_code&)': /usr/in”,我们可以从以下几个方面进行分析和解答: 1. 错误信息分析 错误信息表明在尝试调用boost::hash_value(const std::error_code&)函数时出现了问题。这个函数通常用于计算std::error_code对象的哈希...
For any valuekey1of typeKeythat precedeskey2in the sequence and has the same hash value (value returned by the hash function),hash_comp(key2,key1) is false. The function must impose a total ordering on values of typeKey. The function supplied by hash_compare returnscomp(key2,key1),whe...
