Base64 content transfer encoding per RFCs 2045-2047.
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.
