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.
