```
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.

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.
