Cryptor uses the 256 bit Rijndael (otherwise known as AES, or the Advanced Encryption Standard) encryption to secure files. It does this using a CryptoStream object and the RijndaelManaged class. There is no default form to the application - double clicking Cryptor.exe will achieve nothing. A form is only displayed when the correct command line arguments are passed. This happens when a user has installed the MSI (or added the neccessary keys to the registry) and right clicked on a file (not a folder) in Windows Explorer.-Cryptor uses the 256 bit Rijndael (otherwise known as AES, or the Advanced Encryption Standard) encryption to secure files.
