+/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
+ The following encoding technique is taken from RFC 1521 by Borenstein
+ and Freed. It is reproduced here in a slightly edited form for
+ convenience.
+
+ A 65-character subset of US-ASCII is used, enabling 6 bits to be
+ represented per printable character. (The extra 65th character, "=",
+ is used to signify a special processing function.)
+
+ The encoding process represents 24-bit groups of input bits as output
+ strings of 4 encoded characters. Proceeding from left to right, a
+ 24-bit input group is formed by concatenating 3 8-bit input groups.
+ These 24 bits are then treated as 4 concatenated 6-bit groups, each
+ of which is translated into a single digit in the base64 alphabet.
+
+ Each 6-bit group is used as an index into an array of 64 printable
+ characters. The character referenced by the index is placed in the
+ output string.
+
+ Table 1: The Base64 Alphabet
+
+ Value Encoding Value Encoding Value Encoding Value Encoding
+ 0 A 17 R 34 i 51 z
+ 1 B 18 S 35 j 52 0
+ 2 C 19 T 36 k 53 1
+ 3 D 20 U 37 l 54 2
+ 4 E 21 V 38 m 55 3
+ 5 F 22 W 39 n 56 4
+ 6 G 23 X 40 o 57 5
+ 7 H 24 Y 41 p 58 6
+ 8 I 25 Z 42 q 59 7
+ 9 J 26 a 43 r 60 8
+ 10 K 27 b 44 s 61 9
+ 11 L 28 c 45 t 62 +
+ 12 M 29 d 46 u 63 /
+ 13 N 30 e 47 v
+ 14 O 31 f 48 w (pad) =
+ 15 P 32 g 49 x
+ 16 Q 33 h 50 y
+
+ Special processing is performed if fewer than 24 bits are available
+ at the end of the data being encoded. A full encoding quantum is
+ always completed at the end of a quantity. When fewer than 24 input
+ bits are available in an input group, zero bits are added (on the
+ right) to form an integral number of 6-bit groups. Padding at the
+ end of the data is performed using the '=' character.
+
+ Since all base64 input is an integral number of octets, only the
+ -------------------------------------------------
+ following cases can arise:
+
+ (1) the final quantum of encoding input is an integral
+ multiple of 24 bits; here, the final unit of encoded
+ output will be an integral multiple of 4 characters
+ with no "=" padding,
+ (2) the final quantum of encoding input is exactly 8 bits;
+ here, the final unit of encoded output will be two
+ characters followed by two "=" padding characters, or
+ (3) the final quantum of encoding input is exactly 16 bits;
+ here, the final unit of encoded output will be three
+ characters followed by one "=" padding character.

-+ This package contains the OpenBSD rewrite of netcat, including support

-+OpenBSD netcat for Debian
-+-------------------------
-+
-+This package has been rebased on OpenBSD's implementation of netcat. The
-+code has been massively cleaned up, and important functionality has been
-+added.
-+
-+ -- Soren Hansen <soren@ubuntu.com> Tue, 15 Jan 2008 10:38:34 +0100
-+
-+The OpenBSD implementation has been split from netcat-traditional for
-+two reasons (not counting sentimental value):
-+
-+ 1. Netcat should be part of the base system; OpenBSD netcat uses
-+ strlcpy. While there is already a perfectly good implementation of
-+ strlcpy in Debian, it is part of glib, which is not included in base.
-+ 2. Packages should not be replaced under users' feet; a transitional
-+ package will be provided for lenny so that users can note the new
-+ package and switch if they wish.
-+
-+You may install this package alongside netcat-traditional; they both
-+use the alternatives system for nc(1) as well as the deprecated alias
-+netcat(1). Other implementations of netcat with compatible command line
-+options are encouraged to also do so and provide the virtual package
-+"netcat".
-+
-+The following features from netcat-traditional will not be added to this
-+package:
-+
-+ * The -e and -c options (This should be done by redirecting the
-+ appropriate file descriptors, not within netcat. How to do so should
-+ be better documented.)
-+ * Printing "connection refused" messages when -v is not specified
-+ (because there is only one level of verbosity in this netcat, and
-+ that message is primarily what the option is for.)
-+
-+Anything else that netcat-traditional does that this package doesn't
-+is a bug. Wherever possible, command-line compatibility with the BSDs
-+and Fedora is desired, but it should be easy to use netcat-openbsd as a
-+"drop-in" replacement for netcat-traditional as well.

-+## Web proxy, following the grand tradition of Web things being handled by
-+## gross scripts. Uses netcat to listen on a high port [default 8000],
-+## picks apart requests and sends them on to the right place. Point this
-+## at the browser client machine you'll be coming from [to limit access to
-+## only it], and point the browser's concept of an HTTP proxy to the
-+## machine running this. Takes a single argument of the client that will
-+## be using it, and rejects connections from elsewhere. LOGS the queries
-+## to a configurable logfile, which can be an interesting read later on!
-+## If the argument is "reset", the listener and logfile are cleaned up.
-+##
-+## This works surprisingly fast and well, for a shell script, although may
-+## randomly fail when hammered by a browser that tries to open several
-+## connections at once. Drop the "maximum connections" in your browser if
-+## this is a problem.
-+##
-+## A more degenerate case of this, or preferably a small C program that
-+## does the same thing under inetd, could handle a small site's worth of
-+## proxy queries. Given the way browsers are evolving, proxies like this
-+## can play an important role in protecting your own privacy.

-+/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
-+ The following encoding technique is taken from RFC 1521 by Borenstein
-+ and Freed. It is reproduced here in a slightly edited form for
-+ convenience.
-+
-+ A 65-character subset of US-ASCII is used, enabling 6 bits to be
-+ represented per printable character. (The extra 65th character, "=",
-+ is used to signify a special processing function.)
-+
-+ The encoding process represents 24-bit groups of input bits as output
-+ strings of 4 encoded characters. Proceeding from left to right, a
-+ 24-bit input group is formed by concatenating 3 8-bit input groups.
-+ These 24 bits are then treated as 4 concatenated 6-bit groups, each
-+ of which is translated into a single digit in the base64 alphabet.
-+
-+ Each 6-bit group is used as an index into an array of 64 printable
-+ characters. The character referenced by the index is placed in the
-+ output string.
-+
-+ Table 1: The Base64 Alphabet
-+
-+ Value Encoding Value Encoding Value Encoding Value Encoding
-+ 0 A 17 R 34 i 51 z
-+ 1 B 18 S 35 j 52 0
-+ 2 C 19 T 36 k 53 1
-+ 3 D 20 U 37 l 54 2
-+ 4 E 21 V 38 m 55 3
-+ 5 F 22 W 39 n 56 4
-+ 6 G 23 X 40 o 57 5
-+ 7 H 24 Y 41 p 58 6
-+ 8 I 25 Z 42 q 59 7
-+ 9 J 26 a 43 r 60 8
-+ 10 K 27 b 44 s 61 9
-+ 11 L 28 c 45 t 62 +
-+ 12 M 29 d 46 u 63 /
-+ 13 N 30 e 47 v
-+ 14 O 31 f 48 w (pad) =
-+ 15 P 32 g 49 x
-+ 16 Q 33 h 50 y
-+
-+ Special processing is performed if fewer than 24 bits are available
-+ at the end of the data being encoded. A full encoding quantum is
-+ always completed at the end of a quantity. When fewer than 24 input
-+ bits are available in an input group, zero bits are added (on the
-+ right) to form an integral number of 6-bit groups. Padding at the
-+ end of the data is performed using the '=' character.
-+
-+ Since all base64 input is an integral number of octets, only the
-+ -------------------------------------------------
-+ following cases can arise:
-+
-+ (1) the final quantum of encoding input is an integral
-+ multiple of 24 bits; here, the final unit of encoded
-+ output will be an integral multiple of 4 characters
-+ with no "=" padding,
-+ (2) the final quantum of encoding input is exactly 8 bits;
-+ here, the final unit of encoded output will be two
-+ characters followed by two "=" padding characters, or
-+ (3) the final quantum of encoding input is exactly 16 bits;
-+ here, the final unit of encoded output will be three
-+ characters followed by one "=" padding character.
