Unigine::Checksum Class

Checksum Class

Members

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

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

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

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 )

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

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

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 )

Arguments

Return value

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

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.
