base64encode
encodes a data into base64 encoding. The source
can be a file, binary connection or a raw vector.
base64decode
decodes a base64-encoded string into binary
data. The source can be a string or a connection, the output is
either a raw vector (output=NULL
) or a binary connection.

base64encode
: A character vector. If linewith > 0
and
newline
is not set then it will consist of as many elements
as there are lines. Otherwise it is a single string.
base64decode
: If output = NULL
then a raw vector with
the decoded content, otherwise the number of bytes written into the
connection.
