Functions

encode(Data) -> Base64

  • Data = string() | binary()
  • Base64 = binary()

encode_to_string(Data) -> Base64String

Encodes a plain ASCII string into base64. The result will be 33% larger than the data.

decode(Base64) -> Data

  • Base64 = string() | binary()
  • Data = binary()

decode_to_string(Base64) -> DataString

  • Base64 = string() | binary()
  • DataString = string()

mime_decode(Base64) -> Data

  • Base64 = string() | binary()
  • Data = binary()

mime_decode_to_string(Base64) -> DataString

  • Base64 = string() | binary()
  • DataString = 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.
