This package contains a Base64 encoder/decoder and a quoted-printable
|
|
encoder/decoder. These encoding methods are specified in RFC 2045 -
|
|
MIME (Multipurpose Internet Mail Extensions).
|
|
|
|
The Base64 encoding is designed to represent arbitrary sequences of
|
|
octets in a form that need not be humanly readable. A 65-character
|
|
subset ([A-Za-z0-9+/=]) of US-ASCII is used, enabling 6 bits to be
|
|
represented per printable character.
|
|
|
|
The quoted-printable encoding is intended to represent data that
|
|
largely consists of bytes that correspond to printable characters in
|
|
the ASCII character set. Non-printable characters are represented by
|
|
a triplet consisting of the character "=" followed by two hexadecimal
|
|
digits.
|
|
|
|
The MIME::Base64 and MIME::QuotedPrint modules used to be part of
|
|
libwww-perl package. They are now distributed separately (this
|
|
package). The main improvement is that the Base64 encoder/decoder is
|
|
implemented by XS functions. This makes it about 20 times faster than
|
|
the old implementation in perl.
