Function `std.digest.WrapperDigest.finish`

The finish function returns the hash value. It takes an optional buffer to copy the data into. If a buffer is passed, it must have a length at least length bytes.


						
				ubyte[] finish(
				
  ubyte[] buf
				

				) nothrow;
				

				
ubyte[] finish() nothrow @trusted;

Example


import std.digest.md;
ubyte[16] buf;
auto hash = new WrapperDigest!MD5();
hash.put(cast(ubyte) 0);
auto result = hash.finish(buf[]);
//The result is now in result (and in buf). If you pass a buffer which is bigger than
//necessary, result will have the correct length, but buf will still have it's original
//length
