Signing ✍ and Verifying ✅ Asymmetric Encryption Decryption with RSA Implementation

This is Bob and Alice's secure message transaction implementation demonstration application. Specifically, I’m sharing how to sign and verify asymmetric encryption and decryption with the RSA crypto service in this article. As I mentioned in a previous article, since this is a public key sharing approach, the public key can…

Asymmetric Encryption and Decryption implementation using the RSA algorithm.

In this article, I’m going to present asymmetric encryption and decryption implementation using the RSA algorithm provided by the cryptographic service provider (CSP). for simplicity let's consider there are only three objects/people involving in this transaction. (for this application, I implement one-direction transactions only) Bob (Reciever) Alice (Sender) Eve (Eavesdropper) …

Connecting to DB with both Windows authentication and SQL Server authentication in .NET

There can be situations where we have to use both windows authentication connections strings and SQL server authentication connection strings. for such situations, we can do an impersonation approach. Example ConnectionStrings can place like the following This is the Impersonate Class we can use for this App settings values need set like the following for the Windows User. So We have to update our source code on the Windows authentication access side like the following, SQL authentication side not require any upgrade.
