Data.Text.Encoding.Base64

Description

This module contains the combinators implementing the RFC 4648 specification for the Base64 encoding including unpadded and lenient variants

Synopsis

encodeBase64 :: Text -> Text
decodeBase64 :: Text -> Either Text Text
decodeBase64Lenient :: Text -> Text
isBase64 :: Text -> Bool
isValidBase64 :: Text -> Bool

Documentation

encodeBase64 :: Text -> Text Source #

Encode a Text value in Base64 with padding.

See: RFC-4648 section 4

decodeBase64 :: Text -> Either Text Text Source #

Decode a padded Base64-encoded Text value

See: RFC-4648 section 4

decodeBase64Lenient :: Text -> Text Source #

Leniently decode a Base64-encoded Text 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.

Note: This is not RFC 4648-compliant.

isBase64 :: Text -> Bool Source #

Tell whether a Text value is Base64-encoded.

isValidBase64 :: Text -> Bool Source #

Tell whether a Text value is a valid Base64 format.

This will not tell you whether or not this is a correct Base64 representation, only that it conforms to the correct shape. To check whether it is a true Base64 encoded Text value, use isBase64.
