Decrypt ( byte data, RSAEncryptionPadding padding ) : byte[]
Decrypt ( byte rgb, bool fOAEP ) : byte[]	Decrypt raw data, generally used for decrypting symmetric key material
Encrypt ( byte data, RSAEncryptionPadding padding ) : byte[]
Encrypt ( byte rgb, bool fOAEP ) : byte[]	Encrypt raw data, generally used for encrypting symmetric key material. This method can only encrypt (keySize - 88 bits) of data, so should not be used for encrypting arbitrary byte arrays. Instead, encrypt a symmetric key with this method, and use the symmetric key to encrypt the sensitive data.
