The API allows to set an align mask. This mask is considered on the allocation of cipher's private ctx and the IV (for block cipher). This mask is ignored in the setkey function (what is fine with me). encrypt() and decrypt() functions get their data through a scatterlist. Is my understanding correct that I can't assume any alignment of the input / output data? If so, is it fungible to modify the caller's code to respect the aligmask?
