* This class computes the SHA1 hash of a byte sequence, or of the concatenation
* of multiple sequences. For example, computing the SHA1 of two sequences of
* bytes could be done as follows:
*
* void SHA1(const uint8_t* buf1, uint32_t size1,
* const uint8_t* buf2, uint32_t size2,
* SHA1Sum::Hash& hash)
* {
* SHA1Sum s;
* s.update(buf1, size1);
* s.update(buf2, size2);
* s.finish(hash);
* }
*
* The finish method may only be called once and cannot be followed by calls
* to update.
