Data.ByteString.Base64
Description
Fast and efficient encoding and decoding of base64-encoded strings.
- encode :: ByteString -> ByteString
- decode :: ByteString -> Either String ByteString
- decodeLenient :: ByteString -> ByteString
- joinWith :: ByteString -> Int -> ByteString -> ByteString
Documentation
encode :: ByteString -> ByteStringSource
Encode a string into base64 form. The result will always be a multiple of 4 bytes in length.
decode :: ByteString -> Either String ByteStringSource
Decode a base64-encoded string. This function strictly follows the specification in RFC 4648, http://www.apps.ietf.org/rfc/rfc4648.html.
decodeLenient :: ByteString -> ByteStringSource
Decode a base64-encoded string. This function is lenient in following the specification from RFC 4648, http://www.apps.ietf.org/rfc/rfc4648.html, and will not generate parse errors no matter how poor its input.
Arguments
| :: ByteString | String to intersperse and end with |
| -> Int | Interval at which to intersperse, in bytes |
| -> ByteString | String to transform |
| -> ByteString |
Efficiently intersperse a terminator string into another at regular intervals, and terminate the input with it.
Examples:
joinWith "|" 2 "----" = "--|--|"
joinWith "\r\n" 3 "foobarbaz" = "foo\r\nbar\r\nbaz\r\n"
