msgid "**Source code:** :source:`Lib/base64.py`"
"This module provides functions for encoding binary data to printable ASCII "
"characters and decoding such encodings back to binary data. This includes "
"the :ref:`encodings specified in <base64-rfc-4648>` :rfc:`4648` (Base64, "
"Base32 and Base16), the :ref:`Base85 encoding <base64-base-85>` specified in "
"`PDF 2.0 <https://pdfa.org/resource/iso-32000-2/>`_, and non-standard "
"variants of Base85 used elsewhere."
"There are two interfaces provided by this module.  The modern interface "
"supports encoding :term:`bytes-like objects <bytes-like object>` to ASCII :"
"class:`bytes`, and decoding :term:`bytes-like objects <bytes-like object>` "
"or strings containing ASCII to :class:`bytes`.  Both base-64 alphabets "
"defined in :rfc:`4648` (normal, and URL- and filesystem-safe) are supported."
"The :ref:`legacy interface <base64-legacy>` does not support decoding from "
"strings, but it does provide functions for encoding and decoding to and "
"from :term:`file objects <file object>`.  It only supports the Base64 "
"standard alphabet, and it adds newlines every 76 characters as per :rfc:"
"`2045`.  Note that if you are looking for :rfc:`2045` support you probably "
"want to be looking at the :mod:`email` package instead."
"ASCII-only Unicode strings are now accepted by the decoding functions of the "
"modern interface."
"Any :term:`bytes-like objects <bytes-like object>` are now accepted by all "
"encoding and decoding functions in this module.  Ascii85/Base85 support "
msgid "RFC 4648 Encodings"
"The :rfc:`4648` encodings are suitable for encoding binary data so that it "
"can be safely sent by email, used as parts of URLs, or included as part of "
"an HTTP POST request."
"Encode the :term:`bytes-like object` *s* using Base64 and return the "
"encoded :class:`bytes`."
"Optional *altchars* must be a :term:`bytes-like object` of length 2 which "
"specifies an alternative alphabet for the ``+`` and ``/`` characters. This "
"allows an application to e.g. generate URL or filesystem safe Base64 "
"strings.  The default is ``None``, for which the standard Base64 alphabet is "
"If *padded* is true (default), pad the encoded data with the '=' character "
"to a size multiple of 4. If *padded* is false, do not add the pad characters."
"If *wrapcol* is non-zero, insert a newline (``b'\\n'``) character after at "
"most every *wrapcol* characters. If *wrapcol* is zero (default), do not "
"insert any newlines."

"Optional *altchars* must be a :term:`bytes-like object` or ASCII string of "
"length 2 which specifies the alternative alphabet used instead of the ``+`` "
"and ``/`` characters."
"If *padded* is true, the last group of 4 base 64 alphabet characters must be "
"padded with the '=' character. If *padded* is false, padding is neither "
"required nor recognized: the '=' character is not treated as padding but as "
"a non-alphabet character, which means it is silently discarded when "
"*validate* is false, or causes an :exc:`~binascii.Error` when *validate* is "
"true unless b'=' is included in *ignorechars*."
"A :exc:`binascii.Error` exception is raised if *s* is incorrectly padded."
"If *ignorechars* is specified, it should be a :term:`bytes-like object` "
"containing characters to ignore from the input when *validate* is true. If "
"*ignorechars* contains the pad character ``'='``,  the pad characters "
"presented before the end of the encoded data and the excess pad characters "
"will be ignored. The default value of *validate* is ``True`` if "
"*ignorechars* is specified, ``False`` otherwise."
"If *validate* is false, characters that are neither in the normal base-64 "
"alphabet nor (if *ignorechars* is not specified) the alternative alphabet "
"are discarded prior to the padding check, but the ``+`` and ``/`` characters "
"keep their meaning if they are not in *altchars* (they will be discarded in "
"future Python versions)."
"If *validate* is true, these non-alphabet characters in the input result in "
"a :exc:`binascii.Error`."
"If *canonical* is true, non-zero padding bits are rejected. See :func:"
"`binascii.a2b_base64` for details."

"Optional *casefold* is a flag specifying whether a lowercase alphabet is "
"acceptable as input.  For security purposes, the default is ``False``."
":rfc:`4648` allows for optional mapping of the digit 0 (zero) to the letter "

msgid "Added the *ignorechars* parameter."
msgid "Base85 Encodings"
"Base85 encoding is a family of algorithms which represent four bytes using "
"five ASCII characters.  Originally implemented in the Unix ``btoa(1)`` "
"utility, a version of it was later adopted by Adobe in the PostScript "
"language and is standardized in PDF 2.0 (ISO 32000-2). This version, in both "
"its ``btoa`` and PDF variants, is implemented by :func:`a85encode`."
"A separate version, using a different output character set, was defined as "
"an April Fool's joke in :rfc:`1924` but is now used by Git and other "
"software.  This version is implemented by :func:`b85encode`."
"Finally, a third version, using yet another output character set designed "
"for safe inclusion in programming language strings, is defined by ZeroMQ and "
"implemented here by :func:`z85encode`."
"The functions present in this module differ in how they handle the following:"
msgid "Whether to include and expect enclosing ``<~`` and ``~>`` markers."
msgid "Whether to fold the input into multiple lines."
msgid "The set of ASCII characters used for encoding."
msgid "Compact encodings of sequences of spaces and null bytes."
msgid "The encoding of zero-padding bytes applied to the input."
"Refer to the documentation of the individual functions for more information."
"Encode the :term:`bytes-like object` *b* using Ascii85 and return the "
"encoded :class:`bytes`."
"*foldspaces* is an optional flag that uses the special short sequence 'y' "
"instead of 4 consecutive spaces (ASCII 0x20) as supported by 'btoa'. This "
"feature is not supported by the standard encoding used in PDF."
"*pad* controls whether zero-padding applied to the end of the input is fully "
"retained in the output encoding, as done by ``btoa``, producing an exact "
"multiple of 5 bytes of output. This is not part of the standard encoding "
"used in PDF, as it does not preserve the length of the data."
"*adobe* controls whether the encoded byte sequence is framed with ``<~`` and "
"``~>``, as in a PostScript base-85 string literal.  Note that while "
"ASCII85Decode streams in PDF documents *must* be terminated with ``~>``, "
"they *must not* use a leading ``<~``."
"Decode the Ascii85 encoded :term:`bytes-like object` or ASCII string *b* and "
"return the decoded :class:`bytes`."
"*foldspaces* is a flag that specifies whether the 'y' short sequence should "
"be accepted as shorthand for 4 consecutive spaces (ASCII 0x20). This feature "
"is not supported by the standard Ascii85 encoding used in PDF and PostScript."
"*adobe* controls whether the ``<~`` and ``~>`` markers are present. While "
"the leading ``<~`` is not required, the input must end with ``~>``, or a :"
"exc:`ValueError` is raised."
"*ignorechars* should be a :term:`bytes-like object` containing characters to "
"ignore from the input. This should only contain whitespace characters, and "
"by default contains all whitespace characters in ASCII."
"If *canonical* is true, non-canonical encodings are rejected. See :func:"
"`binascii.a2b_ascii85` for details."
"Added the *canonical* parameter. Single-character final groups are now "
"always rejected as encoding violations."
"Encode the :term:`bytes-like object` *b* using base85 (as used in e.g. git-"
"style binary diffs) and return the encoded :class:`bytes`."
"The input is padded with ``b'\\0'`` so its length is a multiple of 4 bytes "
"before encoding.  If *pad* is true, all the resulting characters are "
"retained in the output, which will always be a multiple of 5 bytes, and thus "
"the length of the data may not be preserved on decoding."
"Decode the base85-encoded :term:`bytes-like object` or ASCII string *b* and "
"return the decoded :class:`bytes`."
"If *canonical* is true, non-canonical encodings are rejected. See :func:"
"`binascii.a2b_base85` for details."
"Added the *canonical* and *ignorechars* parameters. Single-character final "
"groups are now always rejected as encoding violations."
"Encode the :term:`bytes-like object` *s* using Z85 (as used in ZeroMQ) and "
"return the encoded :class:`bytes`."
"The input is padded with ``b'\\0'`` so its length is a multiple of 4 bytes "
"before encoding.  If *pad* is true, all the resulting characters are "
"retained in the output, which will always be a multiple of 5 bytes, as "
"required by the ZeroMQ standard."
msgid "The *pad* parameter was added."
"Decode the Z85-encoded :term:`bytes-like object` or ASCII string *s* and "
"return the decoded :class:`bytes`."
msgid "Legacy Interface"
"Decode the contents of the binary *input* file and write the resulting "
"binary data to the *output* file. *input* and *output* must be :term:`file "
"objects <file object>`. *input* will be read until ``input.readline()`` "
"returns an empty bytes object."
"Decode the :term:`bytes-like object` *s*, which must contain one or more "
"lines of base64 encoded data, and return the decoded :class:`bytes`."
"Encode the contents of the binary *input* file and write the resulting "
"base64 encoded data to the *output* file. *input* and *output* must be :term:"
"`file objects <file object>`. *input* will be read until ``input.read()`` "
"returns an empty bytes object. :func:`encode` inserts a newline character "
"(``b'\\n'``) after every 76 bytes of the output, as well as ensuring that "
"the output always ends with a newline, as per :rfc:`2045` (MIME)."
"Encode the :term:`bytes-like object` *s*, which can contain arbitrary binary "
"data, and return :class:`bytes` containing the base64-encoded data, with "
"newlines (``b'\\n'``) inserted after every 76 bytes of output, and ensuring "
"that there is a trailing newline, as per :rfc:`2045` (MIME)."
