Mark Thom e5fbdeb3a9 Merge pull request #568 from triska/logo 
How about an actual raven for a logo?
 2020-05-27 00:19:41 -03:00
Markus Triska 7cc92ec1c1 ADDED: Logo. 
Motivation and considerations:

- A Scryer certainly needs a raven. Ravens are among the most
  intelligent animals on earth.
- When writing Prolog programs, a few strokes are often enough.
- Purple is the colour most associated with magic and royalty,
  indicating the almost surreal and pure features provided by Scryer,
  in the lineage of Marseille Prolog.
- The shape of the silhouette looks a bit like an "S" for "Scryer".
- A square which surrounds the image is traditionally associated with
  finishing a proof (square, Latin "quadratum", has the same starting
  letters as "quod erat demonstrandum").

I call this raven: *Cryer*. Cryer is an archaic spelling for "crier",
an officer who makes public announcements in a court of justice.
The Prolog top-level likewise makes announcements about what is true.

 2020-05-21 11:30:47 -03:00
Markus Triska 1108c99688 document that lists of integers can be specified if encoding(octet) is used 
This seems to be a good compromise: The API now strongly encourages
lists of characters, which are ideally suited to represent text, and
also allows lists of bytes if the encoding(octet) option is used.
 2020-05-21 13:41:57 +02:00
Markus Triska 93da831ef0 correct mode indication for ed25519_verify/4 
Noted by @notoria in #545. Many thanks!

Markus Triska 72bf45912e "PrivateKey" --> "KeyPair" 2020-05-21 00:14:15 +02:00
Markus Triska 5d94276c4f remove several mentions of list of bytes in predicate descriptions 
This is to focus more on the intended core representation of text: In
Prolog, text is ideally represented as a list of characters, and this
is what we want to encourage, especially given Scryer's compact
representation for strings.

For the time being, library(crypto) still also supports lists of bytes in
several predicates. This will likely be removed at some point in the
future. Please use lists of characters to make your code future-proof.

Markus Triska 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.

Markus Triska 2845f55157 ADDED: ed25519_keypair_public_key/2, relating a key pair to its public key 2020-05-20 23:43:28 +02:00

Markus Triska 0ef7b5488d ADDED: ed25519_new_keypair/1 to dynamically create a new Ed25519 key pair 2020-05-20 23:11:56 +02:00
Markus Triska 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.
 2020-05-20 22:32:39 +02:00
Markus Triska 2d036c6b25 "codes" --> "bytes" 
Support for lists of bytes may be dropped from library(crypto). Use
lists of characters to make your code future-proof. Lists of
characters will always be supported due to their compactness,
and because Prolog applications should move towards characters.
