    Example:

    byte[] - * myByteArray = Base64.decode( encoded );

    The options parameter, which appears in a few - * places, is used to pass several pieces of information to the encoder.

    The constants defined in Base64 can be OR-ed together to combine - * options, so you might make a call like this:

    String encoded = Base64.encodeBytes( mybytes, - * Base64.GZIP | Base64.DO_BREAK_LINES );

    to compress the data before encoding it and then making the output - * have newline characters.

    + * Change Log: + *

    + *
      + *
    • 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.
      • + *
    • 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.
      • + *
    • v2.3.5 - Fixed bug in {@link #encodeFromFile} where estimated buffer size + * was wrong for files of size 31, 34, and 37 bytes.
      • + *
    • 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.
      • + *
    • 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.
      • + *
    • 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).
      • + *
    • 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.
      • + *
    • v2.3 - This is not a drop-in replacement! 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: + *
        + *
      • Does not break lines, by default. This is to keep in compliance with + * RFC3548.
        • + *
      • Throws exceptions instead of returning null values. 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.
        • + *
      • Removed all references to System.out, System.err, and the like. + * Shame on me. All I can say is sorry they were ever there.
        • + *
      • Throws NullPointerExceptions and IllegalArgumentExceptions as needed + * such as when passed arrays are null or offsets are invalid.
        • + *
      • 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.
        • + *
      + *
    • v2.2.1 - Fixed bug using URL_SAFE and ORDERED encodings. Fixed bug + * when using very small files (~< 40 bytes).
      • + *
    • 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: + *
        + *
      1. The default is RFC3548 format.
        2. + *
      2. 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
        3. + *
      3. 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
        4. + *
      + * Special thanks to Jim Kellerman at http://www.powerset.com/ + * for contributing the new Base64 dialects. + *
      • + * + *
    • v2.1 - Cleaned up javadoc comments and unused variables and methods. Added + * some convenience methods for reading and writing to and from files.
      • + *
    • v2.0.2 - Now specifies UTF-8 encoding in places where the code fails on systems + * with other encodings (like EBCDIC).
      • + *
    • v2.0.1 - Fixed an error when decoding a single byte, that is, when the + * encoded data was a single byte.
      • + *
    • 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 (ints that you "OR" together).
      • + *
    • v1.5.1 - Fixed bug when decompressing and decoding to a + * byte[] using decode( String s, boolean gzipCompressed ). + * 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).
      • + *
    • 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.
      • + *
    • v1.4 - Added helper methods to read/write files.
      • + *
    • v1.3.6 - Fixed OutputStream.flush() so that 'position' is reset.
      • + *
    • 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.
      • + *
    • v1.3.4 - Fixed when "improperly padded stream" error was thrown at the wrong time.
      • + *
    • v1.3.3 - Fixed I/O streams which were totally messed up.
      • + *
    + * + *

    + * 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! + * Please visit http://iharder.net/base64 + * periodically to check for updates or to contribute improvements. + *

Subject: [PATCH 65/98] Remove unnecessary nested try/finally (#417)

* Remove unnecessary nested try/finally

* This handles the case of your concern.

An even better solution would be to have SSHClient and Session implement Auto-Closable so then you don't have to worry about doing anything in the finally block!

+ * 
    
+ * This password hashing system tries to thwart off-line password

+ * computers get faster.

+ * To check whether a plaintext password matches one that has been
+ * hashed previously, use the checkpw method:
+ * 
    
+ * 
+ * if (BCrypt.checkpw(candidate_password, stored_hash))
    
+ *     System.out.println("It matches");
    
+ * else
    
+ *     System.out.println("It does not match");
    
+ *     
+ * 
    
+ * The gensalt() method takes an optional parameter (log_rounds)
+ * that determines the computational complexity of the hashing:
+ * 
    
+ * 
+ * String strong_salt = BCrypt.gensalt(10)
    
+ * String stronger_salt = BCrypt.gensalt(12)
    
+ *     
+ * 
    
+ * The amount of work increases exponentially (2**log_rounds), so
+ * each increment is twice as much work. The default log_rounds is
+ * 10, and the valid range is 4 to 30.

+     * 1.5 transport: Protocol 2 Encrypt-then-MAC MAC algorithms
+     * 
    
+     * OpenSSH supports MAC algorithms, whose names contain "-etm", that
+     * perform the calculations in a different order to that defined in RFC
+     * 4253. These variants use the so-called "encrypt then MAC" ordering,
+     * calculating the MAC over the packet ciphertext rather than the
+     * plaintext. This ordering closes a security flaw in the SSH transport
+     * protocol, where decryption of unauthenticated ciphertext provided a
+     * "decryption oracle" that could, in conjunction with cipher flaws, reveal
+     * session plaintext.
+     * 
    
+     * Specifically, the "-etm" MAC algorithms modify the transport protocol
+     * to calculate the MAC over the packet ciphertext and to send the packet
+     * length unencrypted. This is necessary for the transport to obtain the
+     * length of the packet and location of the MAC tag so that it may be
+     * verified without decrypting unauthenticated data.
+     * 
    
+     * As such, the MAC covers:
+     * 
    
+     * mac = MAC(key, sequence_number || packet_length || encrypted_packet)
+     * 
    
+     * where "packet_length" is encoded as a uint32 and "encrypted_packet"
+     * contains:
+     * 
    
+     * byte      padding_length
+     * byte[n1]  payload; n1 = packet_length - padding_length - 1
+     * byte[n2] random padding; n2 = padding_length

Subject: [PATCH 83/98] Add lock timeout for remote action (fixes #466) (#468)

When the remove window size is expanded, a condition is waited on until
the remote server acknowledges and completes the action. If the server
does not respond, e.g. due to a connectivity issue, then this blocks the
client indefinitely. Instead the client waits up to the connection's
timeout (500 min default) and fails. This allows users to set a reasonable
timeout, fail their operations, and retry accordingly.

Subject: [PATCH 97/98] Fix local port forwarding disconnecting issue (#491)

* `SocketStreamCopyMonitor` closes channel after setting the one event. It doesn't wait for the second stream to finish the job.

* #317 Fix `SocketStreamCopyMonitor` to wait for all events before closing the channel.
