Android platform des IV encryption and decryption essaysA good memory is better than a bad pen, so I started blogging. On the one hand to deepen their understanding, two to the back of beginners less detours, no matter how difficult, some things may not understand the depth, welcome you master guidance and spit Groove!Des encryption has been in contact many times

In a. NET application, MD5CryptoServiceProvider is instantiated, causing this implementation to be not a part of the Windows Platform FIPS validated cryptogr Aphic algorithms exception. That means md5cryptoserviceprovider.

A problem occurred:This problem occurs because of a booking assistant. NET uses the MD5 algorithm, and the system's Group Policy security settings prevent this algorithm from being used.To fix this problem, follow these steps (choose one of the two methods).
