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

NAME

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

DESCRIPTION

Implements base 64 encode and decode, see RFC2045.

DATA TYPES


ascii_string() = [1..255]

 

EXPORTS


encode(Data) -> Base64

 
 

encode_to_string(Data) -> Base64String

 
 
Types:
 
Data = string() | binary()
 
Base64 = binary()
 
Base64String = ascii_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. 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.
