ADDED: Password-based key derivation (PBKDF2) ( #509 )
...
The new predicates crypto_password_hash/[2,3] let you store
passwords safely, and easily verify passwords later.

ADDED: HMAC-based key derivation (HKDF) via crypto_data_hkdf/4
...
This is useful to generate keys and initialization vectors
from suitable input keying material, so that future predicates
for symmetric encryption can be used with appropriate parameters.

ADDED: Reasoning about elliptic curves in library(crypto).
...
This is useful to establish shared secrets, using ECDH key exchange.
Note that CLP(ℤ) goal expansion is currently disabled due to #445 ,
and this slows down the computations considerably for the time being.

ADDED: crypto_n_random_bytes/2, creating cryptographically secure random bytes
...
The ring crate is used since it will be needed also for future
predicates in library(crypto).
