Detailed Description

Sensitive-data wiping helpers.

Function Documentation

WipeBuffer()

template<typename Container >

void keepass::detail::WipeBuffer ( Container *  buffer )

inline

Zeroizes the contents of a contiguous container (std::string, std::string view or std::vector<char/uint8_t>) in place. std::string_view::data() is const even in C++17, so cast it away for the wipe; writing zeros never invalidates the container invariants.

WipeStream()

void keepass::detail::WipeStream ( std::stringstream &  stream )

inline

Zeroizes the buffered content of a stringstream in place, so that decrypted plaintext or transient header material does not linger in the heap after parsing or encrypting.
