Detailed Description

Incremental SHA-256.

Feed it with update(), read the digest once with hex().

The object is SPENT by hex(): the padding is appended to the running state rather than to a copy, so a second call would digest the padding again. The two free functions below are the intended interface; this class is public only because a caller hashing something that is not a file or a string needs somewhere to put the loop.
