base64(3)

base64(3erl)               Erlang Module Definition               base64(3erl)

NAME
       base64 - Provides base64 encode and decode, see
           RFC 2045.

DESCRIPTION
       Provides base64 encode and decode, see RFC 2045.

DATA TYPES
       ascii_string() = [1..255]

       ascii_binary() = binary()

              A binary() with ASCII characters in the range 1 to 255.

EXPORTS
       decode(Base64) -> Data

       decode_to_string(Base64) -> DataString

       mime_decode(Base64) -> Data

       mime_decode_to_string(Base64) -> DataString

              Types:

                 Base64 = ascii_string() | ascii_binary()
                 Data = ascii_binary()
                 DataString = ascii_string()

              Decodes a base64-encoded string to plain ASCII. See RFC 4648.

              mime_decode/1  and  mime_decode_to_string/1  strip  away illegal
              characters, while decode/1  and  decode_to_string/1  only  strip
              away whitespace characters.

       encode(Data) -> Base64

       encode_to_string(Data) -> Base64String

              Types:

                 Data = ascii_string() | ascii_binary()
                 Base64 = ascii_binary()
                 Base64String = ascii_string()

              Encodes  a  plain  ASCII  string  into base64. The result is 33%
              larger than the data.
