C# BouncyCastle Encryption Wrapper Class

-- Specs --

I need a C# wrapper class around the [url removed, login to view] encryption and compression library that will take file names as parameters and de/compress and en/decrypt them.

Encryption Algorithm is always TrippleDes

-Public Key used to encrypt

-Private key with a passphrase used to decrypt

Compression Algorithm is always BZip2 with compression level 9

This class will be used to compress and encrypt PDF files before sending them over the internet, and then decrypt and decompress after the files have been received.

-- Interface --

The wrapper class needs to implement the following interface:

Constructors:

BCWrapper(string PublicKeyPath);

BCWrapper(string PrivateKeyPath, string PassPhrase);

BCWrapper(string PublicKeyPath, string PrivateKeyPath, string PassPhrase);

Methods:

//Encrypts the file specified in UnencryptedFilePath using TripleDes algorithm and places the encrypted file into the EncryptedFilePath. Uses the public key specified in the constructor.

Encrypt(string UnencryptedFilePath, string EncryptedFilePath);

//Decrypts the file specified in EncryptedFilePath, using the private key and passphrase specified in the constructor.

Decrypt(string EncryptedFilePath, string DecryptedFilePath);

//Compresses the UncompressedFilePath file using BZip2 algorithm and compression level 9 and places the compressed file in CompressedFilePath

Compress(string UncompressedFilePath, string CompressedFilePath);

//Decompresses the CompressedFilePath file, and places it into UncompressedFilePath. CompressedFilePath can be assumed to only contain one file.

Decompress(string CompressedFilePath, string UncompressedFilePath);
