EncryptedConfigValue.NET

In sync with encrypted-config-value v5.2.0 (a104ddefd48e2fb322f5db205f7c93f0ad4ae1d7)

EncryptedConfigValue.NET is a .NET implementation of the Palantir's encrypted-config-value library.

This repository provides tooling for encrypting certain configuration parameter values in ASP.NET Core apps. This defends against accidental leaks of sensitive information such as copy/pasting a config file.

EncryptedConfigValue.AspNetCore

A EncryptedConfigValue.AspNetCore package provides a way of using encrypted values in your ASP.NET Core appsettings.json files.

Currently supported algorithms:

AES: (AES/GCM/NoPadding) with random IV
RSA

Install from NuGet:

Install-Package EncryptedConfigValue.Net.AspNetCore

To use in your app:

// If needed, set environment variable, default is var/conf/encrypted-config-value.key
my-application$ export EncryptedConfigValue_Config_KeyPath=conf/encrypted-config-value.key

// appsettings.json
{
  "Encrypted": "${enc:INNv4cGkVF45MLWZhgVZdIsgQ4zKvbMoJ978Es3MIKgrtz5eeTuOCLM1vPbQm97ejz2EK6M=}",
}

// Program.cs
using EncryptedConfigValue.AspNetCore;
using EncryptedConfigValue.Crypto;

// Optionally you can set environment variable in application
// Environment.SetEnvironmentVariable(KeyFileUtils.KeyPathProperty, "conf/encrypted-config-value.key");

var builder = WebApplication.CreateBuilder(args).AddEncryptedConfigValueProvider();

EncryptedConfigValue.Cli

A EncryptedConfigValue.Cli project provides CLI tools for generating keys and encrypting values.

The CLI tool provides following commands:

encrypt-config-value [-v <value>] [-k <keyfile>] for encrypting values. In the case of non-symmetric algorithms (e.g. RSA) specify the public key. If -v <value> not provided, program will explicitly ask about value by running interactive mode. On Windows OS it is recommended to provide keyfile parameter as default path points to var\conf\encrypted-config-value.key.
generate-random-key -a <algorithm> [-f <keyfile>] for generating random keys with the specified algorithm. In the case of non-symmetric algorithms (e.g. RSA) the private key will have a .private extension. On Windows OS it is recommended to provide keyfile parameter as default path points to var\conf\encrypted-config-value.key.

Currently supported algorithms:

AES: (AES/GCM/NoPadding) with random IV
RSA

Install from NuGet:

dotnet tool install -g EncryptedConfigValue.Net.Cli

To generate keys:

my-application$ encrypted-config-value-dotnet generate-random-key -a AES
Wrote key to var/conf/encrypted-config-value.key

To encrypt value:

my-application$ encrypted-config-value-dotnet encrypt-config-value -v "secret-value"

EncryptedConfigValue.Module

You can use EncryptedConfigValue.Module to create your own decrypt provider.

Install from NuGet:

Install-Package EncryptedConfigValue.Net.Module
