ComputeSHA
public static final byte[] ComputeSHA(byte[] MT, byte[] result, int offset) Does Dallas SHA, as specified in DS1963S datasheet. result is in intel Endian format, starting with the LSB of E to the MSB of E followed by the LSB of D. result array should be at least 20 bytes long, after the offset.- Parameters:
MT
- The message block (padded if necessary).result
- The byte[] into which the result will be copied.offset
- The starting location in 'result' to start copying.

ComputeSHA
public static final void ComputeSHA(byte[] MT, int[] ABCDE) Does Dallas SHA, as specified in DS1963S datasheet. result is in intel Endian format, starting with the LSB of E to the MSB of E followed by the LSB of D.- Parameters:
MT
- The message block (padded if necessary).ABCDE
- The result will be copied into this 5-int array.
