base64 Implements base 64 encode and decode, see RFC2045.

Implements base 64 encode and decode, see RFC2045.

encode(Data) -> Base64 encode_to_string(Data) -> Base64String Encodes data into base64. 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 Decodes a base64 encoded string to data. Base64 = string() | binary() Data = binary() DataString = string()

Decodes a base64 encoded string to plain ASCII. See RFC4648. mime_decode/1 and mime_decode_to_string/1 strips away illegal characters, while decode/1 and decode_to_string/1 only strips away whitespace characters.
