Data wiping functions.

Member Enumeration Documentation

strong

Wipe options.

Enumerator
Dod7Pass	DOD 7-pass (default)
Simple	Overwrite with single pass of zero bytes (quicker but less secure).

static bool dipki::Wipe::Data ( bvec_t & data )

static

Zeroise then clear data in memory.

Parameters

data	data to be wiped

Returns: true if successful; false if fails
dipki::bvec_t bv = dipki::str2bvec("Some secret data");

dipki::Wipe::Data(bv);

cout << "After Wipe::Data='" << dipki::Cnv::ToHex(bv) << "'" << endl;

// After Wipe::Data=''

dipki::Cnv::ToHex
static std::string ToHex(const bvec_t &bv)
Encodes an array of bytes as a hexadecimal-encoded string.

dipki::Wipe::Data
static bool Data(bvec_t &data)
Zeroise then clear data in memory.

dipki::bvec_t
std::vector< unsigned char > bvec_t
A vector of bytes (our typedef for a byte array)
Definition: dipki.hpp:79

dipki::str2bvec
bvec_t str2bvec(const std::string &s)
Convert a string to a byte vector.

static

Securely wipe and delete a file.

Parameters

fileName	Name of file to be wiped
opts	Options (optional, default = DOD 7-pass)

static bool dipki::Wipe::String ( std::string & s )

static

Zeroise then clear a string.

Parameters

s	String to be wiped

Returns: true if successful; false if fails
std::string s = "More secret data";

dipki::Wipe::String(s);

cout << "After Wipe::String='" << s << "'" << endl;

// After Wipe::String=''

dipki::Wipe::String
static bool String(std::string &s)
Zeroise then clear a string.
