Microsoft.IdentityModel.Protocols.OpenIdConnectProtocolInvalidNonceException

I was using openId connect authentication with IdentityServer (v4) in a recent project and my client application was throwing following error: Microsoft.IdentityModel.Protocols.OpenIdConnectProtocolInvalidNonceException: IDX10311: RequireNonce is 'true' (default) but validationContext.Nonce is null. A nonce cannot be validated. If you don't need to check the nonce, set OpenIdConnectProtocolValidator.RequireNonce to 'false'. at Microsoft.IdentityModel.Protocols.OpenIdConnectProtocolValidator.ValidateNonce(JwtSecurityToken jwt, OpenIdConnectProtocolValidationContext validationContext) in c:\workspace\WilsonForDotNet45Release\src\Microsoft.IdentityModel.Protocol.Extensions\OpenIdConnectProtocolValidator.cs:line 332 at Microsoft.IdentityModel.Protocols.OpenIdConnectProtocolValidator.Validate(JwtSecurityToken jwt, OpenIdConnectProtocolValidationContext validationContext) in c:\workspace\WilsonForDotNet45Release\src\Microsoft.IdentityModel.Protocol.Extensions\OpenIdCo...

TypeScript - keeping compiled files in a separate directory

Image
When we use TypeScripts in visual studio projects, the compiled JavaScript (.js) files generated from the TypeScripts (.ts) are saved by default in the same directory where the ts files are located. Sometimes it could be annoying for example: if we want to ignore the compiled js files from source control. We can separate the directory for the compiled files very easily with a simple project setting. Lets say we have a folder structure in a visual studio solution as in below: As you can see, we have different folders for different modules inside our script folder and I've added the "js" folder to put all the compiled javascript files inside it so that I can ignore them from source control. To do this, I've changed the "TypeScript Build" settings (using Visual Studio 2015) from the project properties dialog: Notice that I've checked to redirect the JavaScript output to a directory. If you don't want to generate mapping files, you should u...

Adding security headers to prevent XSS and MiTM attacks in .Net Core

Image
As a developer, we need to consider security when designing and building web applications. HTTP Response Headers allow server to pass additional information to instruct browsers how to handle sensitive data and content of the application and/or from external or untrusted sources. HTTP response security headers provide an extra layer of protection to help mitigating vulnerabilities and attacks. One way to add those security headers from .Net Core application is by writing a custom action filter that would be executed before serving any response from the application. Below is a example of the custom attribute: To apply this globally for all responses, we can add this to the Startup class as in below: To apply trusted source for any particular action: And here is the outcome: HAPPY CODING   👌
