It is not like if/when we find SHA-1 is inadequate we would just switch to SHA-256 and redefine HASH_BYTES from 20 to 32 and be done with it. With the need for backward compatibility, we would probably end up changing "unsigned char sha1[20]" to something that allows us to tell which hash function's result we are talking about, like:

	struct {
	       	enum { SHA_1, SHA_256 } type;
               	union {
                        unsigned char sha1[20];
                        unsigned char sha256[32];
		} u;
	};
