184ef94e7e ENHANCED: throw Prolog exception on expired certificates 
Example:

    ?- socket_client_open('expired.badssl.com':443, S, [tls(true)]).
    caught: error(permission_error(open,source_sink,'expired.badssl.com'),socket_client_open/3)

b43f27030e require PKCS#8 v2 format for better security 
Notably, this format requires that the public key also be present.
This format is what ed25519_new_keypair/1 generates, and it is
strongly encouraged for higher security.

56b04f8df8 use LessSafeKey to simplify the implementation of authenticated encryption 
The nonce is explicitly specified, and the application programmer
must (and always had to) ensure that it is unique for a given key.

fd732550d8 crypto_data_hkdf/4: Fail if the length is too long. 
Due to the way the counter is constructed in the HKDF specification,
the requested output length can be at most 255 times the size of the
digest algorithm's output.

Reported by @notoria in #527. Many thanks!

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.
