libntru 0.5

Changes since 0.4.1:

• RNGs: NTRU_RNG_DEFAULT uses CTR_DRBG now, NTRU_RNG_CTR_DRBG replaces NTRU_RNG_IGF2. This change breaks the API!
• Denser encoding of private keys. This change breaks binary compatibility!
• new API feature: multiple public keys for the same private key
• new parameter sets: EES443EP1 and EES587EP1
• new #defines for referencing param sets by strength: NTRU_DEFAULT_PARAMS_xxx_BITS
• BSD support
• bugfixes:
  • fixed deterministic encryption on big-endian machines
  • fixed some incorrect error codes when key generation failed
  • fixed generation of polynomial g which deviated from the standard
  • fixed SSE detection on BSD
  • fixed buffer overruns (thanks Jeffrey Quesnelle)
  • fixed a resource leak
  • fixed tests on ARMv6
  • fixed calculation of M_len
• AVX2 optimizations (thanks Shay Gueron and Fabian Schlieker)
• minor optimizations

libntru 0.4

Changes since 0.3:

• new Makefile targets for distros (thanks Julian Ospald)
• made the library C++ friendly (thanks Ruben De Smet)
