Using Digital Signatures to check integrity of cipher texts in ASP.NET Core Razor Pages

This post shows how digital signatures can be implemented to check the integrity of cipher texts in ASP.NET Core Razor Pages. The cipher texts are encrypted with AES symmetric encryption and the key and the IV required to decrypt the texts are encrypted with asymmetric encryption using RSA certificates with a key size of 3072. […]

Encrypting texts for an Identity in ASP.NET Core Razor Pages using AES and RSA

The article shows how encrypted texts can be created for specific users in an ASP.NET Core Razor page application. Symmetric encryption is used to encrypt the text or the payload. Asymmetric encryption is used to encrypt the AES key and the IV of the symmetric encryptions. Each ASP.NET Core Identity has an associated X509Certificate2 with […]

Symmetric and Asymmetric Encryption in .NET Core

This post looks at symmetric and asymmetric encryption and how this could be implemented in .NET Core. Symmetric encryption is fast and can encrypt or decrypt large amounts of text, streams or files but requires a shared key. Asymmetric encryption can be used without shared a key, but can only encrypt or decrypt small texts […]
