Value members
Concrete methods
Converts a stream of base 64 text in to a stream of bytes.
Converts a stream of base 64 text in to a stream of bytes.
If the text is not valid base 64, the pipe fails with an exception. Padding characters at the end of the input stream are optional, but if present, must be valid per the base 64 specification. Whitespace characters are ignored.
The default base 64 alphabet is used by this pipe.
