SSH.NET

SSH.NET

SSH.NET is a Secure Shell (SSH) library for .NET, optimized for parallelism.

##Introduction This project was inspired by Sharp.SSH library which was ported from java and it seems like was not supported for quite some time. This library is a complete rewrite, without any third party dependencies, using parallelism to achieve the best performance possible.

##Features

• Execution of SSH command using both synchronous and asynchronous methods
• Return command execution exit status and other information
• Provide SFTP functionality for both synchronous and asynchronous operations
• Provides SCP functionality
• Provide status report for upload and download sftp operations to allow accurate progress bar implementation
• Remote, dynamic and local port forwarding
• Shell/Terminal implementation
• Specify key file pass phrase
• Use multiple key files to authenticate
• Supports 3des-cbc, aes128-cbc, aes192-cbc, aes256-cbc, aes128-ctr, aes192-ctr, aes256-ctr, blowfish-cbc, cast128-cbc, arcfour and twofish encryptions
• Supports publickey, password and keyboard-interactive authentication methods
• Supports RSA and DSA private key
• Supports DES-EDE3-CBC, DES-EDE3-CFB, DES-CBC, AES-128-CBC, AES-192-CBC and AES-256-CBC algorithms for private key encryption
• Supports two-factor or higher authentication
• Supports SOCKS4, SOCKS5 and HTTP Proxy

##Key Exchange Method

SSH.NET supports the following key exchange methods:

• diffie-hellman-group-exchange-sha256
• diffie-hellman-group-exchange-sha1
• diffie-hellman-group14-sha1
• diffie-hellman-group1-sha1

##Message Authentication Code

SSH.NET supports the following MAC algorithms:

• hmac-md5
• hmac-md5-96
• hmac-sha1
• hmac-sha1-96
• hmac-sha2-256
• hmac-sha2-256-96
• hmac-sha2-512
• hmac-sha2-512-96
• hmac-ripemd160
• hmac-ripemd160@openssh.com

##Framework Support SSH.NET supports the following target frameworks:

• .NET Framework 3.5
• .NET Framework 4.0
• Silverlight 4
• Silverlight 5
• Windows Phone 7.1
• Windows Phone 8.0
• Universal Windows Platform 10

In our codebase, we use the following conditional compilation symbols to identity features supported by a given target framework:
