I see 3 alternatives: use the original NaCl, use the unofficial fork libsodium, or use TweetNaCl. The latter shares the same authors as the original NaCl, with the advantage of being much smaller.

I don't like the fact that TinySSH modified TweetNaCl, and added back MD5:

  /*
  Based on tweetnacl 20140427 (http://tweetnacl.cr.yp.to   software.html)
  - updated int/uint types to crypto_int/crypto_uint
  - added crypto_stream_chacha20
  - added crypto_hash_sha256
  - added crypto_hash_md5
  */

I mean they use TweetNaCl because it has "state-of-the-art crypto", but then they add back MD5. Something is wrong here ...
