This module handles the content transfer encoding method defined in RFC 2045 to encode arbitrary 8-bit data using the three 8-bit bytes in four 7-bit characters encoding known as Base64. It is used in the MIME standards for email to attach images, audio, and text using some 8-bit character sets to messages. This module provides an interface to encode and decode both headers and bodies with Base64 encoding. RFC 2045 defines a method for including character set information in an `encoded-word' in a header. This method is commonly used for 8-bit real names in To:, From:, Cc:, etc. fields, as well as Subject: lines. This module does not do the line wrapping or end-of-line character conversion necessary for proper internationalized headers; it only does dumb encoding and decoding. To deal with the various line wrapping issues, use the email.header module. �body_decode�body_encode�decode�decodestring� header_encode� header_length� )� b64encode)� b2a_base64� a2b_base64z � � � c C s* t t| �d�\}}|d }|r&|d7 }|S )z6Return the length of s when it is encoded with base64.� � )�divmod�len)� bytearrayZgroups_of_3Zleftover�n� r �"/usr/lib64/python3.6/base64mime.pyr 2 s � iso-8859-1c C s6 | sdS t | t�r| j|�} t| �jd�}d||f S )z�Encode a single header line with Base64 encoding in a given charset. charset names the character set to use to encode the header.
