Unigine::SHA1 Class

Header: #include <UnigineChecksum.h>

SHA1 Class

Members


static SHA1Ptr create ( ) #

Default constructor that creates an empty instance.

void begin ( ) #

Initializes a 160-bit SHA1 checksum with an initial value.

void update ( const void* data, int size ) #

Updates a 160-bit SHA1 checksum.

Arguments

  • const void* data - Input data pointer.
  • int size - Input data size, in bytes.

void end ( unsigned int* value, bool big_endian ) #

Finalizes the checksum value by inverting all bits.

Arguments

  • unsigned int* value - 160-bit SHA1 checksum (array of 5 unsigned int elements).
  • bool big_endian - Byte ordering flag. Set true to use the big-endian order; false — to use the little-endian order.

int calculate ( const void* data, int size, bool big_endian ) #

Calculates a 160-bit SHA1 checksum.

Arguments

  • const void* data - Input data pointer.
  • int size - Input data size, in bytes.
  • bool big_endian - Byte ordering flag. Set true to use the big-endian order; false — to use the little-endian order.

Return value

160-bit SHA1 checksum.

void calculate ( unsigned int* value, const void* data, int size, bool 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.
  • bool big_endian - Byte ordering flag. Set true to use the big-endian order; false — to use the little-endian order.
