Detailed Description

Constant-time comparison helpers for auth secrets and lookup keys.

Function Documentation

constant_time_string_equal()

bool mcp::auth::constant_time_string_equal ( std::string_view  lhs, std::string_view  rhs  )

inlinenoexcept

Compare two strings without data-dependent early exit.

The loop covers the longer input so equal-prefix mismatches and length mismatches do not return early through std::string::operator==.
