New Protocols
----------------------------------------

* SSHv2 client and/or server
* Cash schemes (such as Lucre, credlib, bitcoin?)

  Accelerators / backends
----------------------------------------

* Extend OpenSSL provider (cipher modes, ECDH, HMAC)
* /dev/crypto
* Windows CryptoAPI
* Apple CommonCrypto
* ARMv8 crypto extensions
* Intel Skylake SHA-1/SHA-2

FFI (Python, OCaml)
----------------------------------------

* Expose certificates
* Expose TLS

Symmetric Algorithms, Hashes, ...
----------------------------------------

* Bitsliced AES or Camellia
* Camellia with AES-NI
* Serpent using AVX2
* Serpent using SSSE3 pshufb for sboxes
* ChaCha20 using SSE2 or AVX2
* scrypt
* bcrypt PBKDF
* BLAKE2b
* Skein-MAC
* ARIA (Korean block cipher, RFCs 5794 and 6209)
* Extend Cascade_Cipher to support arbitrary number of ciphers

Public Key Crypto, Math
----------------------------------------

* EdDSA (GH #283)
* Ed448-Goldilocks
* FHMQV
* Support mixed hashes and non-empty param strings in OAEP
* Fast new implementations/algorithms for ECC point operations,
  Montgomery multiplication, multi-exponentiation, ...
* Some PK operations, especially RSA, have extensive computations per
  operation setup but many of the computed values depend only on the
  key and could be shared across operation objects.
* Have BigInt '%' and '/' operators compute and cache the Barrett
  reduction value on the BigInt.

Library Infrastructure
----------------------------------------
* Add logging callbacks
* Add latency tracing framework
* Compute cycles/byte estimates for benchmark output

Build
----------------------------------------

* Code signing for Windows installers
