Hello,
at Twine CIpher, I am looking at the specification ( https://pdfs.semanticscholar.org/26b9/d188fc506fb34247c57dc365547f961576d7.pdf ). At the top of page 4 there is algorithm of 80bit key schedule.
In your code you follow this algorithm very well, but I can't find the line 8 of algorithm in your code (bitwise Rot4 in WK_0 - WK_3). This should shift WK_3 to WK_2, WK_2 to WK_1, WK_1 to WK_0 and WK_0 to WK_3, but it isn't there.
I believe this step is missing and it should be at line 128 of your code. Am I right?
I didn't run your implementation, but I am quite sure it doesn't compute the same result as test vectors.
Also, 128bit key schedule is missing (I am working on it).
