Nice!, that's the first time anyone's coded any of this.

It looks like you interpreted this line as returning a single cipher
context (cc), whereas it was intended to return a cipher context *and*
a chaining variable (cv):

cv1, cc1 = KDF(dh1, cv, SUITE_NAME || kdf_num, CV_LEN + CC_LEN)

Maybe that would be clearer if written like:

cv1 || cc1 = KDF(dh1, cv, SUITE_NAME || kdf_num, CV_LEN + CC_LEN)
