wordkey/lists/en.txt is the large wordlist for passphrases of the EFF,
7776 words, CC BY 4.0 under its copyright policy, without the dice number
of each line and in its order, so that the position of a word still gives
its dice, 11111 for the first. encrypt -new-words takes it by default, as
the author decided; -dic es takes the Spanish one. The alphabet of en is a
to z and the ASCII hyphen of its four compound words, such as t-shirt,
kept so that no word loses its dice. lists/README.md records its source,
the SHA-256 of the download, the change and the license.

The seed of TestGenerate, bytes.Repeat([]byte{7, 1, 200, 33}, 64), only
ever gives indices 1793 and 2081: both calls of Generate ended in EOF, the
test ignored the errors and compared two empty results. It now draws from
a SHA-256 counter stream and checks the errors and the count, draws an
index twice to see that it is drawn again, and keeps the old seed as the
case of a source that runs out. Found by the review of the Dart port.

wordkey.CheckList takes the language of the list and refuses a word with a
character that is not a letter of its alphabet, which only the code gives:
for es, a to z, the five vowels with an acute accent, u with diaeresis and
n with tilde, in lower case and NFC. A Cyrillic letter that looks like a
Latin one, a capital, a digit or the carriage return of a file with CRLF
lines would be written down and typed again with another character, and
the capsule would not open. The Spanish list passes as it is; its SHA-256
does not change.
wordkey.Bits is the strength of the words that Generate draws, log2 of the
number of draws in order, and encrypt -new-words prints it: 90 bits for 7
words of 7776.

wordkey.Generate draws words uniformly with crypto/rand from a built-in
list, and encrypt -new-words FILE writes them to a new file (-dic, default
es; -word-count, default 7). wordkey.List and CheckList refuse a list of
fewer than 2048 words or with two words that are one once normalized
(spec 38.1). The Spanish list, 7776 words, is a draft not yet reviewed,
licensed CC BY-SA 4.0 as an adaptation of FrequencyWords; its source,
method and SHA-256 are in wordkey/lists/README.md.
