Data.Text.PgpWordlist.Internal.Convert

Core functionality for conversion between binary formats and PGP word lists.

valuetoText :: ByteString -> Text

Inverse of fromText, modulo whitespace count.

Example1 expression

>>> toText (BSL.pack [104, 101, 108, 108, 111])"frighten glossary glucose handiwork gremlin"

valuefromText :: Text -> Either TranslationError ByteString

Convert a text of whitespace-separated words to their binary representation. The whitespace splitting behaviour is given by words.

Example1 expression

>>> fromText (T.pack "frighten glossary glucose handiwork gremlin")Right "hello"

Invalid words are recognized:

Example1 expression

>>> fromText (T.pack "frighten dragon glucose handiwork gremlin")Left (BadWord "dragon")

Typical mistakes include accidentally swapping numbers, which leads to a parity error:

Example1 expression

>>> fromText (T.pack "frighten glucose glossary handiwork gremlin")Left (BadParity "glucose" 108)

valuetoEvenWord :: Word8 -> EvenWord

Look up the word corresponding to a byte.

valuetoOddWord :: Word8 -> OddWord

Look up the word corresponding to a byte.

valuefromEvenWord :: Text -> Either TranslationError Word8

Simple conversion, taking into account invalid words.

valuefromOddWord :: Text -> Either TranslationError Word8

Simple conversion, taking into account invalid words.

valuelookupEvenOdd :: Text -> (Maybe Word8, Maybe Word8)

Look up a word in both databases.

valueevenMap :: Word8Bimap EvenWord

Mapping from and to EvenWords

valueoddMap :: Word8Bimap OddWord

Mapping from and to OddWords
