Implements base 64 encode and decode, see RFC2045.
Implements base 64 encode and decode, see RFC2045.
Types
ascii_string() = [1..255]
ascii_binary() = binary()
A binary() with ASCII characters in the range 1 to 255.
Functions
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 will be 33% larger than the data.
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 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.
