Module Summary
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
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
Encodes a plain ASCII string into base64. The result is 33% larger than the data.
