(import (data base64))

Encoding and decoding of binary data in Base64 format.


syntax: (base64-option symbol)

syntax: (base64-options symbol ...)

The enumeration has the members uri-safe and padding.


procedure: (base64-encode bytevector)

procedure: (base64-encode bytevector options)

Encodes the given bytevector into a string. Without options, the result has no padding and uses the default Base64 alphabet. With the uri-safe option, the characters "-" and "_" replace "+" and "/" in the alphabet. With the padding option, the output may be terminated by "=" characters unless the input length is a multiple of three.

procedure: (base64-encode string)

Decodes the given string into a bytevector. Accepts encodings in the standard or uri-safe alphabets and ignores any number of padding characters at the end of the input.
