|
This module perform base-64 encoding and decoding of arbitrary binary
|
||
|
|
strings into text strings that can be safely emailed or posted. The
|
||
|
|
encoding scheme is defined in RFC 1421 and is used for MIME email and
|
||
|
|
various other Internet-related applications; it is not the same as the
|
||
|
|
output produced by the \file{uuencode} program. For example, the
|
||
|
|
string \code{'www.python.org'} is encoded as the string
|
||
|
|
\code{'d3d3LnB5dGhvbi5vcmc=\e n'}.

\begin{funcdesc}{decode}{input\, output}
|
||
|
|
Decode the contents of the \var{input} file and write the resulting
|
||
|
|
binary data to the \var{output} file.
|
||
|
|
\var{input} and \var{output} must either be file objects or objects that
|
||
|
|
mimic the file object interface. \var{input} will be read until
|
||
|
|
\code{\var{input}.read()} returns an empty string.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{decodestring}{s}
|
||
|
|
Decode the string \var{s}, which must contain one or more lines of
|
||
|
|
base-64 encoded data, and return a string containing the resulting
|
||
|
|
binary data.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{encode}{input\, output}
|
||
|
|
Encode the contents of the \var{input} file and write the resulting
|
||
|
|
base-64 encoded data to the \var{output} file.
|
||
|
|
\var{input} and \var{output} must either be file objects or objects that
|
||
|
|
mimic the file object interface. \var{input} will be read until
|
||
|
|
\code{\var{input}.read()} returns an empty string.

|

|
|
|
||
|
|
\begin{funcdesc}{encodestring}{s}
|
||
|
|
Encode the string \var{s}, which can contain arbitrary binary data,
|
||
|
|
and return a string containing one or more lines of
|
||
|
|
base-64 encoded data.
