base64(3)

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.
