* <p><b>Domain name</b> validation routines.</p>
*
* <p>
* This validator provides methods for validating Internet domain names
* and top-level domains.
* </p>
*
* <p>Domain names are evaluated according
* to the standards <a href="http://www.ietf.org/rfc/rfc1034.txt">RFC1034</a>,
* section 3, and <a href="http://www.ietf.org/rfc/rfc1123.txt">RFC1123</a>,
* section 2.1. No accomodation is provided for the specialized needs of
* other applications; if the domain name has been URL-encoded, for example,
* validation will fail even though the equivalent plaintext version of the
* same name would have passed.
* </p>
*
* <p>
* Validation is also provided for top-level domains (TLDs) as defined and
* maintained by the Internet Assigned Numbers Authority (IANA):
* </p>
*
* <ul>
* <li>{@link #isValidInfrastructureTld} - validates infrastructure TLDs
* (<code>.arpa</code>, etc.)</li>
* <li>{@link #isValidGenericTld} - validates generic TLDs
* (<code>.com, .org</code>, etc.)</li>
* <li>{@link #isValidCountryCodeTld} - validates country code TLDs
* (<code>.us, .uk, .cn</code>, etc.)</li>
* </ul>
*
* <p>
* (<b>NOTE</b>: This class does not provide IP address lookup for domain names or
* methods to ensure that a given domain name matches a specific IP; see
* {@link java.net.InetAddress} for that functionality.)
* </p>

/**
* <p>Encodes and decodes to and from Base64 notation.</p>
* <p>Homepage: <a href="http://iharder.net/base64">http://iharder.net/base64</a>.</p>
*
* <p>Example:</p>
*
* <code>String encoded = Base64.encode( myByteArray );</code>
* <br />
* <code>byte[] myByteArray = Base64.decode( encoded );</code>
*
* <p>The <tt>options</tt> parameter, which appears in a few places, is used to pass
* several pieces of information to the encoder. In the "higher level" methods such as
* encodeBytes( bytes, options ) the options parameter can be used to indicate such
* things as first gzipping the bytes before encoding them, not inserting linefeeds,
* and encoding using the URL-safe and Ordered dialects.</p>
*
* <p>Note, according to <a href="http://www.faqs.org/rfcs/rfc3548.html">RFC3548</a>,
* Section 2.1, implementations should not add line feeds unless explicitly told
* to do so. I've got Base64 set to this behavior now, although earlier versions
* broke lines by default.</p>
*
* <p>The constants defined in Base64 can be OR-ed together to combine options, so you
* might make a call like this:</p>
*
* <code>String encoded = Base64.encodeBytes( mybytes, Base64.GZIP | Base64.DO_BREAK_LINES );</code>
* <p>to compress the data before encoding it and then making the output have newline characters.</p>
* <p>Also...</p>
* <code>String encoded = Base64.encodeBytes( crazyString.getBytes() );</code>
*
*
*
* <p>
* Change Log:
* </p>
* <ul>
* <li>v2.3.7 - Fixed subtle bug when base 64 input stream contained the
* value 01111111, which is an invalid base 64 character but should not
* throw an ArrayIndexOutOfBoundsException either. Led to discovery of
* mishandling (or potential for better handling) of other bad input
* characters. You should now get an IOException if you try decoding
* something that has bad characters in it.</li>
* <li>v2.3.6 - Fixed bug when breaking lines and the final byte of the encoded
* string ended in the last column; the buffer was not properly shrunk and
* contained an extra (null) byte that made it into the string.</li>
* <li>v2.3.5 - Fixed bug in {@link #encodeFromFile} where estimated buffer size
* was wrong for files of size 31, 34, and 37 bytes.</li>
* <li>v2.3.4 - Fixed bug when working with gzipped streams whereby flushing
* the Base64.OutputStream closed the Base64 encoding (by padding with equals
* signs) too soon. Also added an option to suppress the automatic decoding
* of gzipped streams. Also added experimental support for specifying a
* class loader when using the
* {@link #decodeToObject(java.lang.String, int, java.lang.ClassLoader)}
* method.</li>
* <li>v2.3.3 - Changed default char encoding to US-ASCII which reduces the internal Java
* footprint with its CharEncoders and so forth. Fixed some javadocs that were
* inconsistent. Removed imports and specified things like java.io.IOException
* explicitly inline.</li>
* <li>v2.3.2 - Reduced memory footprint! Finally refined the "guessing" of how big the
* final encoded data will be so that the code doesn't have to create two output
* arrays: an oversized initial one and then a final, exact-sized one. Big win
* when using the {@link #encodeBytesToBytes(byte[])} family of methods (and not
* using the gzip options which uses a different mechanism with streams and stuff).</li>
* <li>v2.3.1 - Added {@link #encodeBytesToBytes(byte[], int, int, int)} and some
* similar helper methods to be more efficient with memory by not returning a
* String but just a byte array.</li>
* <li>v2.3 - <strong>This is not a drop-in replacement!</strong> This is two years of comments
* and bug fixes queued up and finally executed. Thanks to everyone who sent
* me stuff, and I'm sorry I wasn't able to distribute your fixes to everyone else.
* Much bad coding was cleaned up including throwing exceptions where necessary
* instead of returning null values or something similar. Here are some changes
* that may affect you:
* <ul>
* <li><em>Does not break lines, by default.</em> This is to keep in compliance with
* <a href="http://www.faqs.org/rfcs/rfc3548.html">RFC3548</a>.</li>
* <li><em>Throws exceptions instead of returning null values.</em> Because some operations
* (especially those that may permit the GZIP option) use IO streams, there
* is a possiblity of an java.io.IOException being thrown. After some discussion and
* thought, I've changed the behavior of the methods to throw java.io.IOExceptions
* rather than return null if ever there's an error. I think this is more
* appropriate, though it will require some changes to your code. Sorry,
* it should have been done this way to begin with.</li>
* <li><em>Removed all references to System.out, System.err, and the like.</em>
* Shame on me. All I can say is sorry they were ever there.</li>
* <li><em>Throws NullPointerExceptions and IllegalArgumentExceptions</em> as needed
* such as when passed arrays are null or offsets are invalid.</li>
* <li>Cleaned up as much javadoc as I could to avoid any javadoc warnings.
* This was especially annoying before for people who were thorough in their
* own projects and then had gobs of javadoc warnings on this file.</li>
* </ul>
* <li>v2.2.1 - Fixed bug using URL_SAFE and ORDERED encodings. Fixed bug
* when using very small files (~< 40 bytes).</li>
* <li>v2.2 - Added some helper methods for encoding/decoding directly from
* one file to the next. Also added a main() method to support command line
* encoding/decoding from one file to the next. Also added these Base64 dialects:
* <ol>
* <li>The default is RFC3548 format.</li>
* <li>Calling Base64.setFormat(Base64.BASE64_FORMAT.URLSAFE_FORMAT) generates
* URL and file name friendly format as described in Section 4 of RFC3548.
* http://www.faqs.org/rfcs/rfc3548.html</li>
* <li>Calling Base64.setFormat(Base64.BASE64_FORMAT.ORDERED_FORMAT) generates
* URL and file name friendly format that preserves lexical ordering as described
* in http://www.faqs.org/qa/rfcc-1940.html</li>
* </ol>
* Special thanks to Jim Kellerman at <a href="http://www.powerset.com/">http://www.powerset.com/</a>
* for contributing the new Base64 dialects.
* </li>
*
* <li>v2.1 - Cleaned up javadoc comments and unused variables and methods. Added
* some convenience methods for reading and writing to and from files.</li>
* <li>v2.0.2 - Now specifies UTF-8 encoding in places where the code fails on systems
* with other encodings (like EBCDIC).</li>
* <li>v2.0.1 - Fixed an error when decoding a single byte, that is, when the
* encoded data was a single byte.</li>
* <li>v2.0 - I got rid of methods that used booleans to set options.
* Now everything is more consolidated and cleaner. The code now detects
* when data that's being decoded is gzip-compressed and will decompress it
* automatically. Generally things are cleaner. You'll probably have to
* change some method calls that you were making to support the new
* options format (<tt>int</tt>s that you "OR" together).</li>
* <li>v1.5.1 - Fixed bug when decompressing and decoding to a
* byte[] using <tt>decode( String s, boolean gzipCompressed )</tt>.
* Added the ability to "suspend" encoding in the Output Stream so
* you can turn on and off the encoding if you need to embed base64
* data in an otherwise "normal" stream (like an XML file).</li>
* <li>v1.5 - Output stream pases on flush() command but doesn't do anything itself.
* This helps when using GZIP streams.
* Added the ability to GZip-compress objects before encoding them.</li>
* <li>v1.4 - Added helper methods to read/write files.</li>
* <li>v1.3.6 - Fixed OutputStream.flush() so that 'position' is reset.</li>
* <li>v1.3.5 - Added flag to turn on and off line breaks. Fixed bug in input stream
* where last buffer being read, if not completely full, was not returned.</li>
* <li>v1.3.4 - Fixed when "improperly padded stream" error was thrown at the wrong time.</li>
* <li>v1.3.3 - Fixed I/O streams which were totally messed up.</li>
* </ul>
*
* <p>
* I am placing this code in the Public Domain. Do with it as you will.
* This software comes with no guarantees or warranties but with
* plenty of well-wishing instead!

/**
* A <code>SFTPv3Client</code> represents a SFTP (protocol version 3) client
* connection tunnelled over a SSH-2 connection. This is a very simple
* (synchronous) implementation.
* <p>
* Basically, most methods in this class map directly to one of the packet types
* described in draft-ietf-secsh-filexfer-02.txt.
* <p>
* Note: this is experimental code.
* <p>
* Error handling: the methods of this class throw IOExceptions. However, unless
* there is catastrophic failure, exceptions of the type {@link SFTPv3Client}
* will be thrown (a subclass of IOException). Therefore, you can implement more
* verbose behavior by checking if a thrown exception if of this type. If yes,
* then you can cast the exception and access detailed information about the
* failure.
* <p>
* Notes about file names, directory names and paths, copy-pasted from the
* specs:
* <ul>
* <li>SFTP v3 represents file names as strings. File names are assumed to use
* the slash ('/') character as a directory separator.</li>
* <li>File names starting with a slash are "absolute", and are relative to the
* root of the file system. Names starting with any other character are relative
* to the user's default directory (home directory).</li>
* <li>Servers SHOULD interpret a path name component ".." as referring to the
* parent directory, and "." as referring to the current directory. If the
* server implementation limits access to certain parts of the file system, it
* must be extra careful in parsing file names when enforcing such restrictions.
* There have been numerous reported security bugs where a ".." in a path name
* has allowed access outside the intended area.</li>
* <li>An empty path name is valid, and it refers to the user's default
* directory (usually the user's home directory).</li>
* </ul>
* <p>
* If you are still not tired then please go on and read the comment for
* {@link #setCharset(String)}.
