I suggest "External Reference. Hash Algorithm. 
Identifier" rather than code because the value is 
not being used for brevity or language 
independence.  All of the algorithms are going to 
be distinguished in instances of this item 
presumably by URI strings of some kind or some 
other patterned value.  So we are dealing with 
probably one scheme for hash algorithm 
identification, and this identifier will be one value in that scheme.

For codes like currency codes and payment means 
codes, values are being truncated or 
substituted.  Whereas this field is identifying 
an algorithm, distinguishing the identifier from other algorithms.

But this is subjective, so I'm not going to 
oppose a considered opinion for "Code".  I just 
wanted to pass along that when I read "Code" my 
initial reaction was that it felt more correct to me to be "Identifier".

I hope this helps.
