* Copied qTESLA-p-I round2 (2019-08-19) code * Code compiles, NIST-KAT works * Included detached signature API * Generated testvectors * Fixed name in api.h * code style * Fixed error in Makefile * Passing pytest * Fixing types (uint8_t bytes and size_t indices) * Replaced SHAKE with SHAKE128 where necessary * Fixed bug: (signed) integer overflow * Added qTESLA-p-III * Code is now independent of machine endianness * repaired Microsoft makefile
