C# BouncyCastle Encryption Wrapper Class

-- Specs -- I need a C# wrapper class around the [login to view URL] 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); -- Files Provided (PM please) -- Public Key file Private Key File Sample Pdf file Sample Compressed and Encrypted file -Encrypted using the public key and TripleDes and then compressed using Bzip2 at compression level 9
