module Data.ByteString.Base64

encodeBase64' :: ByteString -> ByteString

-- | Decode a padded Base64-encoded <a>ByteString</a> value.
--   
--   See: <a>RFC-4648 section 4</a>
--   
--   <i>Note:</i> This function is not RFC compliant, and <b>will</b> add

--   RFC-compliant decoding, use <tt>decodeBase64Unpadded</tt>.
decodeBase64 :: ByteString -> Either Text ByteString

-- | Leniently decode an unpadded Base64-encoded <a>ByteString</a> value.
--   This function will not generate parse errors. If input data contains
--   padding chars, then the input will be parsed up until the first pad
--   character.
--   
--   <b>Note:</b> This is not RFC 4648-compliant.
decodeBase64Lenient :: ByteString -> ByteString

-- | Tell whether a <a>ByteString</a> value is base64 encoded.
isBase64 :: ByteString -> Bool

-- | Tell whether a <a>ByteString</a> value is a valid Base64 format.
--   
--   This will not tell you whether or not this is a correct Base64url
--   representation, only that it conforms to the correct shape. To check
--   whether it is a true Base64 encoded <a>ByteString</a> value, use

module Data.ByteString.Base64.URL

-- | Encode a <a>ByteString</a> value as a Base64url <a>Text</a> value with

--   
--   See: <a>RFC-4648 section 5</a>
encodeBase64' :: ByteString -> ByteString

-- | Decode a padded Base64url encoded <a>ByteString</a> value. If its
--   length is not a multiple of 4, then padding chars will be added to
--   fill out the input to a multiple of 4 for safe decoding as
--   Base64url-encoded values are optionally padded.
--   
--   For a decoder that fails on unpadded input of incorrect size, use
--   <a>decodeBase64Unpadded</a>.
--   
--   See: <a>RFC-4648 section 4</a>
decodeBase64 :: ByteString -> Either Text ByteString

-- | Encode a <a>ByteString</a> value as Base64url <a>Text</a> without
--   padding. Note that for Base64url, padding is optional. If you call
--   this function, you will simply be encoding as Base64url and stripping
--   padding chars from the output.
--   
--   See: <a>RFC-4648 section 3.2</a>

--   added to fill out the input to a multiple of 4.
--   
--   In general, unless unpadded Base64url is explicitly required, it is
--   safer to call <a>decodeBase64</a>.

--   See: <a>RFC-4648 section 4</a>
