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.
