Types
ascii_string() = [1..255]
ascii_binary() = binary()
A binary()
with ASCII characters in the range 1 to
255.
Functions
decode(Base64) -> Data
Base64 = ascii_string() | ascii_binary()
Data = ascii_binary()
decode_to_string(Base64) -> DataString
Base64 = ascii_string() | ascii_binary()
DataString = ascii_string()
mime_decode(Base64) -> Data
Base64 = ascii_string() | ascii_binary()
Data = ascii_binary()
mime_decode_to_string(Base64) -> DataString
Base64 = ascii_string() | ascii_binary()
DataString = ascii_string()
Decodes a base64-encoded string to plain ASCII. See
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
Data = ascii_string() | ascii_binary()
Base64 = ascii_binary()
encode_to_string(Data) -> Base64String
Data = ascii_string() | ascii_binary()
Base64String = ascii_string()
Encodes a plain ASCII string into base64. The result is 33% larger than the data.
