base643erl
Provides base64 encode and decode, see rfc 2045.
Overview
Provides base64 encode and decode, see RFC 2045.
Data types
base64_alphabet() = 65..90 | 97..122 | 48..57 | 43 | 47 | 61
Base 64 Encoding alphabet, see RFC 4648.
base64_string() = [base64_alphabet()]
Base 64 encoded string.
base64_binary() = binary()
Base 64 encoded binary.
byte_string() = [byte()]
Arbitrary sequences of octets.
Exports
decode(Base64) -> Data
decode_to_string(Base64) -> DataString
mime_decode(Base64) -> Data
mime_decode_to_string(Base64) -> DataString
Types:
Base64 = base64_string() | base64_binary()
Data = binary()
DataString = byte_string()
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
Types:
Data = byte_string() | binary()
Base64 = base64_binary()
Base64String = base64_string()
Encodes a plain ASCII string into base64. The result is 33% larger than the data.
