+// HOWEVER, to keep the assembly code simple, some of the counter management is
+// left to the caller. aes_ctr64_crypt_* take the counter in little endian
+// form, only increment the low 64 bits internally, do the conversion to big
+// endian internally, and don't write the updated counter back to memory. The
+// caller is responsible for converting the starting IV to the little endian
+// le_ctr, detecting the (very rare) case of a carry out of the low 64 bits
+// being needed and splitting at that point with a carry done in between, and
+// updating le_ctr after each part if the message is multi-part.
+//
+// aes_xctr_crypt_* implement XCTR as specified in "Length-preserving encryption
+// with HCTR2" (https://eprint.iacr.org/2021/1441.pdf). XCTR is an
+// easier-to-implement variant of CTR that uses little endian byte order and
