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.

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.

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.

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.

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.

give answers for both available encodings.
