base64(3)

MODULE
base64 - Implements base 64 encode and decode, see RFC2045.

DESCRIPTION

Implements base 64 encode and decode, see RFC2045.

EXPORTS

encode(Data) -> Base64
encode_to_string(Data) -> Base64String

    Types
        Data = string() | binary()
        Base64 = binary()
        Base64String = string()

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

decode(Base64) -> Data
decode_to_string(Base64) -> DataString
mime_decode(Base64) -> Data
mime_decode_to_string(Base64) -> DataString

    Types
        Base64 = string() | binary()
        Data = binary()
        DataString = string()

    Decodes a base64 encoded string to plain ASCII. The string should only consist of characters in the base64 set, see RFC4648. mime_decode/1 and mime_decode_to_string/1 strips away illegal characters, while decode/1 and decode_to_string/1 fails if an illegal charactrer is found.
