We define a _digest_ string to match the following grammar:

Above, we have bytestring _C_ passed into a function, _SHA256_, that returns a
bytestring B, which is the hash of _C_. _D_ gets the algorithm concatenated
with the hex encoding of _B_. We then define the identifier of _C_ to _ID(C)_

comparing it with identifier _ID(C)_
Above, we have bytestring `C` passed into a function, `SHA256`, that returns a
bytestring `B`, which is the hash of `C`. `D` gets the algorithm concatenated
with the hex encoding of `B`. We then define the identifier of `C` to `ID(C)`

comparing it with identifier `ID(C)`.
