ConstantTimeCompare

[Source]

Return true if the two ByteSeqs have equal contents. The time taken is independent of the contents, so comparing a secret against a value an attacker supplies does not tell them where the two first differ.

if ConstantTimeCompare(expected_mac, supplied_mac) then
  // ...
end

Sequences of different sizes are not equal, and that is answered before any byte is read.
