CriptoConnectionString

Uma biblioteca .Net para criptografar connection strings em tempo de execução. Lê o arquivo .env e caso não tenha cria um automaticamente. Caso também não tenha uma cliente_key e cliente_iv cria essas chaves poins elas são utilizadas na criptografia da connection string. Lê e criptografa todos os nós da chave ConnectionStrings

Faz isso dinamicamente sem a necessidade de fazer a criptografia externamente e colocar manualmente no appsettings.json.

Descriptografa somente quando for utilizar e fazer a conexão com o banco de dados

Importante

Quando inicia a aplicação pela primeira vez é validado se existe arquivo .env, cliente_key e cliente_iv. Se não tiver é criado o arquivo e as chaves e inserido esses valores no arquivo .env. As chaves cliente_key e cliente_iv são utilizadas na criptografia e Descriptografia da connectionStrings, então se houver alteração dessas chaves a Descriptografia não ira funcionar.

Instalação

Disponivel em NuGet

Visual Studio:

PM> Install-Package CryptoConnectionString

.Net Core CLI:

dotnet add package CryptoConnectionString

Usando

Na Program.cs use o metodo AddCryptoConnectionString(). Por padrão essa função procurará automaticamente um arquivo .env no atual diretorio da aplicação.

	builder.Services.AddCryptoConnectionString(builder.Configuration);

Ou você pode especificar o caminho diretamente do arquivo '.env'

	builder.Services.AddCryptoConnectionString(builder.Configuration, "./path/.env");

Descriptografando

Você pode usar a interface IConnectionStringEncryptor que já está sendo registrada no metodo AddCryptoConnectionString() ou instanciar a classe ConnectionStringEncryptor

	private readonly IConnectionStringEncryptor _connectionStringEncryptor
	
	public Exemplo(IConnectionStringEncryptor connectionStringEncryptor)
	{
		_connectionStringEncryptor=connectionStringEncryptor;
	}
	
	var connString = _connectionStringEncryptor.Decrypt("Valor a ser descriptografado");

Ou

	var encryptor = new ConnectionStringEncryptor();
	
	var connString = encryptor.Decrypt("Valor a ser descriptografado");
