curve25519, chacha20, poly1305

but: currently not yet widespread in "stable" dists (like ubuntu 14.04)

pysodium.crypto_aead_chacha20poly1305_encrypt(b'', data, b'', b"0"*32)

is about twice as fast as:

hashlib.sha512(data).hexdigest()

Note: the first call does not do encryption, it only uses the "additional data (AD)" part of AEAD to compute an 128bit authentication tag over that data.
