HashVal

class HashVal

Stores a 128-bit value that represents the hashed contents (typically MD5) of a file or buffer.

Inheritance diagram

HashVal(void)

HashVal(HashVal const &copy)

vector_uchar as_bin(void) const: Returns the HashVal as a 16-byte binary string.

std::string as_dec(void) const: Returns the HashVal as a string with four decimal numbers.

std::string as_hex(void) const: Returns the HashVal as a 32-byte hexadecimal string.

int compare_to(HashVal const &other) const

void hash_buffer(char const *buffer, std::size_t length): Generates the hash value by hashing the indicated data.

void hash_bytes(vector_uchar const &data): Generates the hash value by hashing the indicated data.

bool hash_file(Filename const &filename): Generates the hash value from the indicated file. Returns true on success, false if the file cannot be read.

void hash_ramfile(Ramfile const &ramfile): Generates the hash value by hashing the indicated data.

bool hash_stream(std::istream &stream): Generates the hash value from the indicated file. Returns true on success, false if the file cannot be read.

void hash_string(std::string_view data): Generates the hash value by hashing the indicated data.

void input_binary(std::istream &in): Inputs the HashVal as a binary stream of bytes in order. This is not the same order expected by read_stream().

void input_dec(std::istream &in): Inputs the HashVal as four unsigned decimal integers.

void input_hex(std::istream &in): Inputs the HashVal as a 32-digit hexadecimal number.

void merge_with(HashVal const &other): Generates a new HashVal representing the xor of this one and the other one.

void output(std::ostream &out) const

void output_binary(std::ostream &out) const: Outputs the HashVal as a binary stream of bytes in order. This is not the same order generated by write_stream().

void output_dec(std::ostream &out) const: Outputs the HashVal as four unsigned decimal integers.

void output_hex(std::ostream &out) const: Outputs the HashVal as a 32-digit hexadecimal number.

void read_datagram(DatagramIterator &source)

void read_stream(StreamReader &source)

bool set_from_bin(vector_uchar const &text): Sets the HashVal from a 16-byte binary string. Returns true if successful, false otherwise.

bool set_from_dec(std::string const &text): Sets the HashVal from a string with four decimal numbers. Returns true if valid, false otherwise.

bool set_from_hex(std::string const &text): Sets the HashVal from a 32-byte hexademical string. Returns true if successful, false otherwise.

void write_datagram(Datagram &destination) const

void write_stream(StreamWriter &destination) const
