NAME
base64 - Provides base64 encode and decode, see RFC 2045.
DESCRIPTION
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.
