This is VaultSharp Version 0.4.1.

With Vault releasing its 0.5.0, VaultSharp Version 0.5.0 is already in progress and coming soon.

This VaultSharp Version 0.4.1 is still completely compatible with Vault 0.5.x

Table of Contents

What is VaultSharp?

  • VaultSharp is a C# Library that can be used in any .NET application to interact with Hashicorp's Vault Service.
  • The Vault system is a secret management system built as an Http Service by Hashicorp.
  • This library supports all the Vault Service Apis documented here: https://www.vaultproject.io/docs/http/

VaultSharp 0.4.x should completely support Vault Service 0.4.0

What is the deal with the Versioning of VaultSharp? (Y U NO 1.0.0)

  • This library is written for the Vault Service version 0.4.0
  • The Vault service is evolving constantly and the Hashicorp team is rapidly working on it.
  • Pretty soon, we should have an 1.0.0 version of the Vault Service from Hashicorp.
  • Because this client library is intended to facilititate the Vault Service operations, this library makes it easier for its consumers to relate to the Vault service it supports.
  • Hence a version of 0.4.x denotes that this library will completely support the Vault 0.4.x Service Apis.
  • Tomorrow when Vault Service gets upgraded to 0.5.x, this library will be modified accordingly and versioned as 0.5.x

How do I use VaultSharp? Give me a code example

// instantiate VaultClient with one of the various authentication options available.
IVaultClient vaultClient = VaultClientFactory.CreateVaultClient(vaultUriWithPort, authenticationInfo);

// use it for operations.
var consulCredentials = await vaultClient.ConsulGenerateDynamicCredentialsAsync(consulRoleName, consulMountPoint);
var consulToken = consulCredentials.Data.Token;

Does VaultSharp support all the Authentication, Secret and Audit Backends?

  • YES
  • All Authentication, Secret and Audit backends are supported by this library.
  • All administrative (seal, unseal, write policy), end-user (generate credentials) and unauthenticated methods (get status, get root CA) are supported by this client.

VaultSharp and 100% Consul Support

  • VaultSharp supports all the secret backends supported by the Vault 0.4.0 Service.
  • This includes 100% support for a Consul Secret backend, which is the recommended secret backend for Vault.
  • Please look at the API usage in the 'Consul' section of 'Secret Backends' below, to see all the Consul related methods in action.

The fundamental READ and WRITE operations on a Vault

  • The generic READ/WRITE Apis of vault allow you to do a variety of operations.
  • A lot or almost all of these operations are supported in a strongly typed manner with dedicated methods for them in this library.
  • However, for some reason, if you want to use the generic READ and WRITE methods of Vault, you can use them as follows:
var path = "cubbyhole/foo/test";

var secretData = new Dictionary<string, object>
{
    {"1", "1"},
    {"2", 2},
    {"3", false},
};

await vaultClient.WriteSecretAsync(path, secretData);

var secret = await vaultClient.ReadSecretAsync(path);
var data = secret.Data; // this is the original dictionary back.

Can I use it in my PowerShell Automation?

  • Absolutely. VaultSharp is a .NET Library.
  • This means, apart from using it in your C#, VB.NET, J#.NET and any .NET application, you can use it in PowerShell automation as well.
  • Load up the DLL in your PowerShell code and execute the methods. PowerShell can totally work with .NET Dlls.

All the methods are async. How do I use them synchronously?

  • The methods are async as the defacto implementation. The recommended usage.
  • However, there are innumerable scenarios where you would continue to want to use it synchronously.
  • For all those cases, there are various options available to you.
  • There is a lot of discussion around the right usage, avoiding deadlocks etc.
  • This library allows you to set the 'continueAsyncTasksOnCapturedContext' option when you initialize the client.
  • It is an optional parameter and defaults to 'false'
  • Setting it to false, allows you to access the .Result property of the task with reduced/zero deadlock issues.
  • There are other ways as well to invoke it synchronously, and I leave it to you guys. (Task.Run etc.)
  • But please note that as much as possible, use it in an async manner.
IVaultClient vaultClient = VaultClientFactory.CreateVaultClient(vaultUriWithPort, authenticationInfo, continueAsyncTasksOnCapturedContext: true);

var consulSecret = vaultClient.ConsulGenerateDynamicCredentialsAsync(consulRole).Result;

Authentication Backends (All of them are supported)

  • VaultSharp supports all the authentication backends supported by the Vault Service 0.4.0
  • Here is a sample to instantiate the vault client with each of the authentication backends.

App Id Authentication Backend

IAuthenticationInfo appIdAuthenticationInfo = new AppIdAuthenticationInfo(mountPoint, appId, userId);
IVaultClient vaultClient = VaultClientFactory.CreateVaultClient(vaultUriWithPort, appIdAuthenticationInfo);

// any operations done using the vaultClient will use the vault token/policies mapped to the app id and user id.

GitHub Authentication Backend

IAuthenticationInfo gitHubAuthenticationInfo = new GitHubAuthenticationInfo(mountPoint, personalAccessToken);
IVaultClient vaultClient = VaultClientFactory.CreateVaultClient(vaultUriWithPort, gitHubAuthenticationInfo);

// any operations done using the vaultClient will use the vault token/policies mapped to the github token.

LDAP Authentication Backend

IAuthenticationInfo ldapAuthenticationInfo = new LDAPAuthenticationInfo(mountPoint, username, password);
IVaultClient vaultClient = VaultClientFactory.CreateVaultClient(vaultUriWithPort, ldapAuthenticationInfo);

// any operations done using the vaultClient will use the vault token/policies mapped to the LDAP username and password.

Certificate (TLS) Authentication Backend

var clientCertificate = new X509Certificate2(certificatePath, certificatePassword, X509KeyStorageFlags.Exportable | X509KeyStorageFlags.PersistKeySet);

IAuthenticationInfo certificateAuthenticationInfo = new CertificateAuthenticationInfo(mountPoint, clientCertificate);
IVaultClient vaultClient = VaultClientFactory.CreateVaultClient(vaultUriWithPort, certificateAuthenticationInfo);

// any operations done using the vaultClient will use the vault token/policies mapped to the client certificate.

Token Authentication Backend

IAuthenticationInfo tokenAuthenticationInfo = new TokenAuthenticationInfo(mountPoint, vaultToken);
IVaultClient vaultClient = VaultClientFactory.CreateVaultClient(vaultUriWithPort, tokenAuthenticationInfo);

// any operations done using the vaultClient will use the vault token/policies mapped to the vault token.

Username and Password Authentication Backend

IAuthenticationInfo usernamePasswordAuthenticationInfo = new UsernamePasswordAuthenticationInfo(mountPoint, username, password);
IVaultClient vaultClient = VaultClientFactory.CreateVaultClient(vaultUriWithPort, usernamePasswordAuthenticationInfo);

// any operations done using the vaultClient will use the vault token/policies mapped to the username/password.

More Administrative & Other operations

  • VaultSharp supports all the operations supported by the Service.
  • These include administrative ones like Inititalize, Unseal, Seal etc.
  • Here are some samples.
await noAuthInfoClient.InitializeAsync(5, 3, null);
await vaultClient.SealAsync();

await vaultClient.UnsealAsync(masterKey); // need to run this in a loop for all master keys
await vaultClient.UnsealQuickAsync(allMasterKeys);  // unseals the Vault in 1 shot.

await vaultClient.GetSealStatusAsync();

// all policy operations

// write a new policy
var newPolicy = new Policy
{
    Name = "gubdu",
    Rules = "path \"sys/*\" {  policy = \"deny\" }"
};

await vaultClient.WritePolicyAsync(newPolicy);

// get new policy
var newPolicyGet = await vaultClient.GetPolicyAsync(newPolicy.Name);
Assert.Equal(newPolicy.Rules, newPolicyGet.Rules);

// write updates to a new policy
newPolicy.Rules = "path \"sys/*\" {  policy = \"read\" }";

await vaultClient.WritePolicyAsync(newPolicy);

// get new policy
newPolicyGet = await vaultClient.GetPolicyAsync(newPolicy.Name);
Assert.Equal(newPolicy.Rules, newPolicyGet.Rules);
