WebDec 25, 2003 · byte[] Encrypt(byte[] clearData, string Password) - encrypts a byte array with a password and returns a byte array; void Encrypt(string fileIn, string fileOut, string Password) - encrypts a file with a password and writes the encrypted bytes into another file. For each of those, there is also a corresponding Decrypt function. The Main method … WebPerformance is compared against AES-128, stated as encrypting "128 bytes" in "30-50 Seconds" on an unspecified platform; which (if we ignore the spurious capital S) is about 2 26 times slower than routinely achieved by a single core of a modern CPU with AES-NI. kristin r wu palo alto arts centet https://recyclellite.com
