Unigine::Checksum Class

Header: #include <UnigineChecksum.h>

Checksum Class

Members


int CRC32 ( const void * data, int size, int big_endian ) #

Calculates a 32-bit CRC checksum.

Arguments

  • const void * data - Input data pointer.
  • int size - Input data size, in bytes.
  • int big_endian - Byte ordering flag. 1 if a big-endian order is used; 0 if a little-endian order is used.

Return value

32-bit CRC checksum.

void MD5 ( unsigned int * value, const void * data, int size, int big_endian ) #

Calculates a 128-bit MD5 checksum.

Arguments

  • unsigned int * value - 128-bit MD5 checksum (array of 4 unsigned int elements).
  • const void * data - Input data pointer.
  • int size - Input data size, in bytes.
  • int big_endian - Byte ordering flag. 1 if a big-endian order is used; 0 if a little-endian order is used.

int MD5 ( const void * data, int size, int big_endian ) #

Calculates a 32-bit MD5 checksum.

Arguments

  • const void * data - Input data pointer.
  • int size - Input data size, in bytes.
  • int big_endian - Byte ordering flag. 1 if a big-endian order is used; 0 if a little-endian order is used.

Return value

32-bit MD5 checksum.

void SHA1 ( unsigned int * value, const void * data, int size, int big_endian ) #

Calculates a 160-bit SHA1 checksum.

Arguments

  • unsigned int * value - 160-bit SHA1 checksum (array of 5 unsigned int elements).
  • const void * data - Input data pointer.
  • int size - Input data size, in bytes.
  • int big_endian - Byte ordering flag. 1 if a big-endian order is used; 0 if a little-endian order is used.

int SHA1 ( const void * data, int size, int big_endian ) #

Calculates a 32-bit SHA1 checksum.

Arguments

  • const void * data - Input data pointer.
  • int size - Input data size, in bytes.
  • int big_endian - Byte ordering flag. 1 if a big-endian order is used; 0 if a little-endian order is used.

Return value

32-bit SHA1 checksum.

void SHA256 ( unsigned int * value, const void * data, int size, int big_endian ) #

Calculates a 256-bit SHA256 checksum.

Arguments

  • unsigned int * value - 256-bit SHA256 checksum (array of 8 unsigned int elements).
  • const void * data - Input data pointer.
  • int size - Input data size, in bytes.
  • int big_endian - Byte ordering flag. 1 if a big-endian order is used; 0 if a little-endian order is used.

int SHA256 ( const void * data, int size, int big_endian ) #

Calculates a 32-bit SHA256 checksum.

Arguments

  • const void * data - Input data pointer.
  • int size - Input data size, in bytes.
  • int big_endian - Byte ordering flag. 1 if a big-endian order is used; 0 if a little-endian order is used.

Return value

32-bit SHA256 checksum.
