Z.Data.Vector.Base64

This module provides base64 encoding & decoding tools, as well as Base64Bytes newtype with base64 textual instances.

Encoding & Decoding functions

base64Encode :: Bytes -> Bytes

Encode Bytes using base64 encoding.

base64EncodeLength :: Int -> Int

Return the encoded length of a given input length, always a multipler of 4.

base64EncodeText :: Bytes -> Text

Text version of base64Encode.

base64EncodeBuilder :: Bytes -> Builder ()

Builder version of base64Encode.

base64Decode :: Bytes -> Maybe Bytes

Decode a base64 encoding string, return Nothing on illegal bytes or incomplete input.

base64Decode' :: HasCallStack => Bytes -> Bytes

Decode a base64 encoding string, throw Base64DecodeException on error.

base64DecodeLength :: Int -> Int

Return the upper bound of decoded length of a given input length , return -1 if illegal(not a multipler of 4).

data Base64DecodeException

Exception during base64 decoding.
