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

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.
