In Office 2016, while there are settings to modify encryption methods, encrypting Open XML Format files (.docx, .xslx, .pptx, etc.) with the default values — AES (Advanced Encryption Standard) with a 256-bit key length, SHA-2, and CBC (cipher block chaining) — provides robust encryptio...
encryption and decryption methods. According to American cryptographer and computer security expert Bruce Schneier, cryptography is “the art and science of keeping messages secure.”The cryptography method transforms plain text into encrypted text (aka ciphertext) using the encryption key, and the ...
Modern cryptography exists through the combination of advanced mathematics, computer science, communication, and engineering processes. Computers and operating systems use complex encryption methods to encode messages so only authorized parties can see them. The message, or plaintext, is converted into cip...

Never store encryption keys in clear text along with the data that they protect. This is akin to locking your front door and placing the key under the doormat. It is the first place an attacker will look. Here are three common methods for protecting keys (from least secure to most secure...
This week's topic is authenticated encryption: encryption methods that ensure both confidentiality and integrity. We will also discuss a few odds and ends such as how to search on encrypted data. This is our last week studying symmetric encryption. Next week we start with key management and pub...

, initially intended to prevent the jamming of Allied torpedoes. Although not directly used in cryptography during the war, her invention laid the groundwork for future secure wireless communications, including Wi-Fi and Bluetooth, representing a major leap in technology and encryption methods....
For example, new StreamWriter(cryptoStream, Encoding.Unicode).using(StreamWriter encryptWriter =new(cryptoStream)) { encryptWriter.WriteLine("Hello World!"); } } } } Console.WriteLine("The file was encrypted."); } catch (Exception ex) { Console.WriteLine($"The encryption failed.{ex}"); }...
