SOCKS and HTTP Proxy Component for .NET
Free, opensource, easy to use .NET 2.0 Component for creating client side proxy connections to SOCKS and HTTP proxy servers. Provides a managed code library giving developers the ability to traverse firewalls using proxy servers from within their own .NET applications.
- Free software with permissive BSD license - no GPL restrictions.
- Easy to add proxy capabilities to any existing .NET projects that use the standard System.Net.SocketsTcpClient class. Returns a standard TcpClient object once the proxy connection has been established.
- Multiple VB.NET and C# examples.
- Connects to SOCKS v4, SOCKS v4a, SOCKS v5, and HTTP proxy servers.
- Factory and abstraction support via the ProxyClientFactory class and IProxyClient interface.
- Use as a DLL or add the source code directly to your project.
- Implements the new Microsoft Asynchronous Model so you can just fire and forget asynchronous calls (no Begin/End needed).
- Integrated Visual Studio.NET help documentation.
- Written in 100% managed C# code.
- Requires .NET 2.0, 3.0, or 3.5.
Example:
|
// create an instance of the client proxy factory
ProxyClientFactory factory = new ProxyClientFactory(); // use the proxy client factory to generically specify the type of proxy to create // the proxy factory method CreateProxyClient returns an IProxyClient object IProxyClient proxy = factory.CreateProxyClient(ProxyType.Http, "localhost", 6588); // create a connection through the proxy to www.starksoft.com over port 80 TcpClient conn = proxy.CreateConnection("www.starksoft.com", 80); |
OpenPGP Component for .NET
Free, open source, easy to use .NET Component for encrypting and decryption data or documents with the free and open source GNU OpenPGP project called GnuPG (or GPG for short).
- Free software with permissive BSD license - no GPL restrictions.
- Multiple VB.NET and C# examples.
- Interfaces directly with the GnuPG GPG.EXE command line tool to encrypt and decrypt data using .NET Streams.
- Locates the GPG.EXE executable two different ways - the Windows registery or by user supplied path.
- Retrieve a collection or DataSet of the keys loaded in the local key ring.
- Use as a DLL or add the source code directly to your project.
- Encrypt and decrypt examples given in C# and VB.NET.
- Asynchronous encryption and decryption examples given in C# and VB.NET.
- Integrated Visual Studio.NET help documentation.
- Accepts any System.IO.Stream object from reading and writing encryption data.
- Output type either as ASCII Armor or Binary
- Supports optional passphrases when decryption data.
- Both Encrypt and Decrypt methods have corresponding EncryptAsync and DecryptAsync methods to support background processing.
- Supports the new Microsoft Asynchronous Model so you can just fire and forget asynchronous calls (no Begin/End needed).
- Written in 100% managed C# code.
- Requires .NET 2.0, 3.0, or 3.5 and GPG.EXE executable.
Encrypt example:
|
// create a new GnuPG object
GnuPG gpg = new GnuPG(); // specify a recipient that is already on the key-ring gpg.Recipient = "myfriend@domain.com"; // create an IO.Stream object to the source of the data and open it FileStream sourceFile = new FileStream(@"c:\temp\source.txt", FileMode.Open); // create an IO.Stream object to a where I want the encrypt data to go FileStream outputFile = new FileStream(@"c:\temp\output.txt", FileMode.Create); // encrypt the data using IO Streams - any type of input and output IO Stream can be used // as long as the source (input) stream can be read and the destination (output) stream // can be written to gpg.Encrypt(sourceFile, outputFile); // close the files sourceFile.Close(); outputFile.Close(); |
Decrypt example:
|
// create
a new GnuPG object
GnuPG gpg = new GnuPG(); // create an IO.Stream object to the encrypted source of the data and open it FileStream encryptedFile = new FileStream(@"output.txt", FileMode.Open); // create an IO.Stream object to a where you want the decrypted data to go FileStream unencryptedFile = new FileStream(@"unencrypted.txt", FileMode.Create); // specify our secret passphrase (if one is used) gpg.Passphrase = "your secret passphrase"; // decrypt the data using IO Streams - any type of input and output IO Stream can be used // as long as the source (input) stream can be read and the destination (output) stream // can be written to gpg.Decrypt(encryptedFile, unencryptedFile); // close the files encryptedFile.Close(); unencryptedFile.Close(); |
