Database access is the most common part of applications. With the introduction of C # and ADO. NET, this operation becomes easier. This article will demonstrate four basic database operations. ● Read data. Data types include integer, string, and

You can use DSA and RSA, for example: Using System; Using System. Text; Using System. Security. Cryptography; Class dsacrypto_SignData {Public static void Main (String [] args ){// Convert the string to a byte array, which is related to
