base64url -package:base64

base64url :: (AsEmpty s1, AsEmpty s2, Cons s1 s1 Word8 Word8, Cons s2 s2 Word8 Word8) => Prism' s1 s2

Prism for encoding / decoding base64url. To encode, review base64url. To decode, preview base64url. Works with any combinations of strict/lazy ByteString.

module Codec.Binary.Base64Url

sandi

Implemented as specified in RFC 4648 (http://tools.ietf.org/html/rfc4648). The difference compared to vanilla Base64 encoding is just in two characters. In Base64 the characters /+ are used, and in Base64Url they are replaced by _- respectively. Please refer to Codec.Binary.Base64 for the details of all functions in this module.

module Data.Conduit.Codec.Base64Url

sandi

base64UrlF :: FormatAsBase64 a => a -> Builder

fmt Fmt Fmt.Internal

Convert a bytestring to base64url (a variant of base64 which omits / and thus can be used in URLs):

>>> base64UrlF ("\0\50\63\80" :: BS.ByteString)
"ADI_UA=="

Base64URLUnpadded :: Base

memory Data.ByteArray.Encoding

unpadded URL-safe Base64

fromBase64URLUnpadded :: Ptr Word8 -> Ptr Word8 -> Int -> IO (Maybe Int)

memory Data.Memory.Encoding.Base64

toBase64URL :: Bool -> Ptr Word8 -> Ptr Word8 -> Int -> IO ()

memory Data.Memory.Encoding.Base64

Transform a number of bytes pointed by src to, URL-safe base64 binary representation in dst. The result will be either padded or unpadded, depending on the boolean padded argument. The destination memory need to be of correct size, otherwise it will lead to really bad things.

toBase64URL :: Bool -> String -> String

basement Basement.String, foundation Foundation.String

Transform string src to URL-safe base64 binary representation. The result will be either padded or unpadded, depending on the boolean padded argument.
