a423eb5323 stronger validation of input lists for cryptographic routines 
Example:

    ?- crypto_data_hkdf(Var, 32, Bs, []).
    caught: error(instantiation_error,must_be/2)

Reported by @notoria in #527. Many thanks!

23034dd4f5 raise instantiation errors for variable encoding 
Reported by notoria in #527.

Note that from a declarative perspective, it would indeed be valid to
give answers for both available encodings.

862ae26631 Authenticated encryption in library(crypto), new encoding/1 option for hashes (#515) 
* shorten n_newlines//1

* remove unneeded variable

* ADDED: authenticated encryption and decryption with ChaCha20-Poly1305

* ADDED: encoding/1 option for crypto_data_hash/3 and crypto_data_hkdf/4

4e69301562 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.

50776748a7 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.

4084005ee7 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.

fd761735d4 ADDED: ripemd160 digest algorithm 
This is used for example for Bitcoin address generation.

716fde5784 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).
