This project was inspired by Sharp.SSH library which was ported from Java.  This library is a complete rewrite using .NET, without any third party dependencies and to utilize the parallelism as much as possible to allow best performance you can get.  SSH.NET supports .NET 3.5, .NET 4.0, Silverlight 4.0, Silverlight 5.0, Windows Phone 7.1 and Windows Phone 8.

2014.4.6-beta2
==============

New Features:

   * Improved accuracy of IsConnected on .NET
   * Added support for ssh.com (SSH-2) private keys (issue #1987)
   * Support an acceptable group of up to 8192 bits for SHA-1 and SHA-256 Diffie-Hellman Group and Key Exchange (issues #1973 and #1777)

Changes:

   * Reduced default buffer size for SftpClient from 64 KB to 32 KB as some SSH servers apply a hard limit of 64 KB at the transport level.

Fixes:

   * SftpClient is throwing undocumented exceptions (issue #2148)
   * Client channels are no longer closed on dispose (issue #1943)
   * SftpClient.Exists(string) returns true for a path that does not exist (issues #1952, #1696 and #1574)
   * ObjectDisposedException when channel is closing (issues #1942 and #1944)
   * Stack overflow during authentication when server returns same allowed methods after partial success (issue #2399)
   * SshCommand doesn't cleanup subscribed events (issue #2295)
   * Lines before protocol identification string are not skipped (issue #1935 and #2223)
   * ShellStream.ReadLine produces incorrect output when reading multi-byte characters (issue #2190)
   * SftpClient constructor throws ArgumentException when host contains underscore (issue #1845)
   * Signing key is missing from source download (issue #2455)
   * Forwarded Port channels can get stuck waiting (issue #1558)
   * NullReferenceException when SftpFileStream is finalized after dispose of session (issue #2013)
   * BlockCipher.Encrypt fails if input message is not padded (issue #2547)
   * ScpClient: Missing files when using DirectoryUpload (issue #1382)
   * Dynamic port forwarding slows down to a crawl (issue #2010)
   * SendKeepAlive causes SocketException when connection is dropped (issue #2029)
   * SocketException on Dispose or Disconnect (issue #2400)
   * Sending EOF on wrong channel number (issue #1877)
   * ForwardedPortDynamic: Unhandled exception if client terminates socket (issue #1844)

2014.4.6-beta1
==============

New Features:

   * Added callbacks to UploadFile, DownloadFile and ListDirectory in SftpClient (issue #1324)
   * Allow a given private key file to be used concurrently
   * Performance improvements:
       - optimization of payload size for both read and write operations (SftpClient only)
       - increase window size from 1MB to 2MB
       - increase buffer size from 16KB to 64KB for SftpClient
       - take into account the maximum remote packet size of the channel for write operations
       - increase maximum size of packets that we can receive from 32 KB to 64 KB
   * Improve exception message for authentication failures

Breaking changes:

   * Assembly name is now Renci.SshNet for all supported frameworks
   * The Renci.SshNet assemblies for .NET and Silverlight are now strong-named (issue #1802)

Fixes:

   * Incorrect copyright in assemblies (issue #1764)
   * Remove linefeed from WriteLine method in Shellstream class (issue #1584)
   * Disable logging of messages in release builds (issue #1767)
   * Stuck loop on key exchange using arcfour encryption (issue #1922)
   * Timeout sending data to server with low window size (issue #1706)
   * No connection possible with the same auth method requested multiple times (issue #1930)
   * Unobserved exception rethrown by finalizer thread (issue #1298 and #1587)
   * Client cipher is used to decrypt server messages (issue #1917)
   * Connection dropped by server due to invalid DSA signature (issue #1918)
   * Correct casing of Security/Cryptography/HMAC.cs to fix build on Linux (issue #1505)
   * HTTP proxy hangs (issue #1890)
   * Wrong parameters to SetSocketOption leads to SocketException under Mono (issue #1799)
   * Incorrect check for timeout values (issue #1620)
   * Wrong PKCS7 padding in DES algorithm (issue #1580)
   * OverflowException on empty server response (issue #1562)
   * Event handle leak (issue #1761)
   * SftpFileStream is very slow (issue #1919)
   * Write access required for private key file
