.NET 6 brings many language improvements in C# 10. Minimal Api is one such feature which allows to create a web api with less boilerplate code. Here is the example which uses Minimal Api for creating an AES Encryption and Decryption api.

using AESEncryptDecrypt;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container. // Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle builder.Services.AddEndpointsApiExplorer(); builder.Services.AddSwaggerGen();

var app = builder.Build();

// Configure the HTTP request pipeline. if (app.Environment.IsDevelopment()) { app.UseSwagger(); app.UseSwaggerUI(); }

app.UseHttpsRedirection();

app.MapPost("/encrypt", (string value) => { string key = app.Configuration["AES:Key"]; string iv = app.Configuration["AES:AES_IV"]; return Results.Ok(AESEncDec.AESEncryption(value, key, iv)); }); app.MapPost("/decrypt", (string value) => { string key = app.Configuration["AES:Key"]; string iv = app.Configuration["AES:AES_IV"]; return Results.Ok(AESEncDec.AESDecryption(value, key, iv)); });

app.Run();
