base64_alphabet() = 65..90 | 97..122 | 48..57 | 43 | 47 | 61
Base 64 Encoding alphabet, see RFC 4648.
Module
base64
Module Summary
Provides base64 encode and decode, see RFC 2045.
Description
Provides base64 encode and decode, see RFC 2045.
Data Types
base64_string() = [base64_alphabet()]
base64_string() = [base64_alphabet()]
Base 64 encoded string.
base64_binary() = binary()
base64_binary() = binary()
Base 64 encoded binary.
byte_string() = [byte()]
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
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
Encodes a plain ASCII string into base64. The result is 33% larger than the data.
