Download and Installation

Prerequisites

dotnet add package Keeper.SecretsManager

Source Code

Find the .Net source code in the GitHub repository

Using the SDK

Initialize Storage

Using token only to generate a new config (for later usage) requires at least one read operation to bind the token and fully populate config.json

In order to retrieve secrets, you must first initialize the local storage on your machine.

SecretsManagerClient.InitializeStorage(storage: KeyValueStorage, clientKey: String? = null, hostName: String? = null)

Example Usage

var storage = new LocalConfigStorage("ksm-config.json");
SecretsManagerClient. InitializeStorage(storage, "[One Time Access Token]");
// Using token only to generate a config (for later usage)
// requires at least one access operation to bind the token
//var options = new SecretsManagerOptions(storage);
//await SecretsManagerClient.GetSecrets(options);

Retrieve Secrets

GetSecrets(options: SecretsManagerOptions, recordsFilter: List<String> = emptyList()): KeeperSecrets

Response

Type: KeeperSecrets

Object containing all Keeper records, or records that match the given filter criteria

Example Usage

Retrieve all Secrets

var options = new SecretsManagerOptions(storage, testPostFunction);
var secrets = GetSecrets(options);

Retrieve Secrets by Title

// get all matching records
async Task<IEnumerable<KeeperRecord>> GetSecretsByTitle(SecretsManagerOptions options, string recordTitle)

// get only the first matching record
async Task<KeeperRecord> GetSecretByTitle(SecretsManagerOptions options, string recordTitle)

Example Usage

using System;
using System.Threading.Tasks;
using SecretsManager;

private static async Task getOneIndividualSecret()
{
    var storage = new LocalConfigStorage("ksm-config.json");
    var options = new SecretsManagerOptions(storage);
    var records = (await SecretsManagerClient.GetSecretsByTitle(
            options, "My Credentials")
        ).Records;
    foreach (var record in records)
    {
        Console.WriteLine(record.RecordUid + " - " + record.Data.title);
        foreach (var field in record.Data.fields)
        {
            Console.WriteLine("\t" + field.label + " (" + field.type + "): [" + String.Join(", ", field.value) + "]");
        }
    }
}

Retrieve Values from a Secret

Retrieve a Password

Get Password

secret.FieldValue("password")

Example Usage

var storage = new LocalConfigStorage(configName);
Console.WriteLine($"Local Config Storage opened from the file {configName}");
if (clientKey != null)
    SecretsManagerClient.InitializeStorage(storage, "<One Time Access Token>");
}
var options = new SecretsManagerOptions(storage);
//get secrets
var secrets= (await SecretsManagerClient.GetSecrets(options)).Records;

// get the password from the first secret
var firstSecret= secrets[0];
var password = firstSecret.FieldValue("password").ToString();

Fields are found by type, for a list of field types see the Record Types documentation.

Retrieve Other Fields Using Keeper Notation

Get Value

GetValue(KeeperSecrets secrets, string notation)

Example Usage

var storage = new LocalConfigStorage(configName);
Console.WriteLine($"Local Config Storage opened from the file {configName}");
if (clientKey != null)
    SecretsManagerClient.InitializeStorage(storage, "<One Time Access Token>");
}
var options = new SecretsManagerOptions(storage);
//get secrets
var secrets (await SecretsManagerClient.GetSecrets(options)).Records;

// get login field value using dot notation
var password = Notation.GetValue(secrets, "BediNKCMG21ztm5xGYgNww/field/login");

See Keeper Notation documentation to learn about Keeper Notation format and capabilities

Retrieve TOTP Code

Get TOTP Code

CryptoUtils.GetTotpCode(string url)

Example Usage

var storage = new LocalConfigStorage(configName);
Console.WriteLine($"Local Config Storage opened from the file {configName}");
if (clientKey != null)
    SecretsManagerClient.InitializeStorage(storage, "<One Time Access Token>");
}
var options = new SecretsManagerOptions(storage);
//get secrets
var secrets (await SecretsManagerClient.GetSecrets(options)).Records;

// get TOTP url from a record
var url = Notation.GetValue(secrets, "BediNKCMG21ztm5xGYgNww/field/OneTimeCode");

// get TOTP code
var totp = CryptoUtils.GetTotpCode(url);
Console.WriteLine(totp.Code);

Update Values in a Secret

Record update commands don't update local record data on success (esp. updated record revision) so any consecutive updates to an already updated record will fail due to revision mismatch. Make sure to reload all updated records after each update batch.

Save Changes to a Secret

Update Secret

UpdateSecret(options: SecretsManagerOptions, record: KeeperRecord);

Example Usage

var options = SecretsManagerOptions(storage, testPostFunction)
updateSecret(options, secret)

Transactional updates

var storage = new LocalConfigStorage(configName);
var options = new SecretsManagerOptions(storage);

//get secrets
var secrets = (await SecretsManagerClient.GetSecrets(options)).Records;

// get the first secret
var secret = secrets[0];

// rotate password on the record
secret.updateFieldValue("password", "MyNewPassword");
//start a transaction
await SecretsManagerClient.UpdateSecret(options, secret, UpdateTransactionType.Rotation);
// rotate password on remote host
success = rotateRemoteSshPassword("MyNewPassword");
// complete the transaction - commit or rollback
await SecretsManagerClient.CompleteTransaction(options, secret.RecordUid, rollback: !success);

Use UpdateSecret to save changes made to a secret record. Changes will not be reflected in the Keeper Vault until UpdateSecret is performed.

Update a Field Value

Update Field Value

UpdateFieldValue(string fieldType, object value)

Example Usage

var storage = new LocalConfigStorage(configName);
Console.WriteLine($"Local Config Storage opened from the file {configName}");
if (clientKey != null)
    SecretsManagerClient.InitializeStorage(storage, "<One Time Access Token>");
}
var options = new SecretsManagerOptions(storage);
//get secrets
var secrets= (await SecretsManagerClient.GetSecrets(options)).Records;

// get the password from the first secret
var firstSecret= secrets[0];

// update the login field
firstSecret.updateFieldValue("login", "My New Login");

// save changes
updateSecret(options, firstSecret);

Generate a Random Password

Generate Password

CryptoUtils.GeneratePassword(int length, lowercase int, uppercase int, digits int, specialCharacters);

Example Usage

// generate a random password
var password = CryptoUtils.GeneratePassword();
// update a record with the new password
firstRecord.UpdateFieldValue("password", password);
await SecretsManagerClient.UpdateSecret(options, firstRecord);

Each parameter indicates the min number of a type of character to include. For example, 'uppercase' indicates the minimum number of uppercase letters to include.

Download a File

DownloadFile(file: KeeperFile): ByteArray

Response

Type: ByteArray

ByteArray of file for download

Download a Thumbnail

DownloadThumbnail(file: KeeperFile): ByteArray

Response

Type: ByteArray

ByteArray of thumbnail for download

Upload a File

Upload File:

UploadFile(SecretsManagerOptions options, KeeperRecord ownerRecord, KeeperFileUpload file)

Creating the Keeper File Upload Object:

KeeperFileUpload(string name, string title, string type, byte[] data)

Example Usage

using System;
using System.Threading.Tasks;
using SecretsManager;

private static async Task uploadFile()
{
    // initalize storage and options
    var storage = new LocalConfigStorage("ksm-config.json");
    var options = new SecretsManagerOptions(storage);
    
    // get a record to attach the file to
    var records = (await SecretsManagerClient.GetSecrets(
            options, new[] { "XXX" })
        ).Records;
        
    var ownerRecord = records[0];
    
    // get file data to upload
    var bytes = await File.ReadAllBytesAsync("my-file.json");
    var myFile = new KeeperFileUpload(
        "my-file1.json", 
        "My File", 
        null, 
        bytes
    );
       
    // upload file to selected record                     
    await SecretsManagerClient.UploadFile(options, firstRecord, myFile);
    
}

Create a Secret

Prerequisites:

• Shared folder UID

  • Shared folder must be accessible by the Secrets Manager Application

  • You and the Secrets Manager application must have edit permission

  • There must be at least one record in the shared folder

• Created records and record fields must be formatted correctly

  • See the documentation for expected field formats for each record type

• TOTP fields accept only URL generated outside of the KSM SDK

• After record creation, you can upload file attachments using UploadFile

Create a Record

SecretsManagerClient.CreateSecret(options, folderUid, record)

Create Record in Sub-folder

SecretsManagerClient.CreateSecret2(options, createOptions, record, folders)

Login Record Example

This example creates a login type record with a login value and a generated password.

Replace '[FOLDER UID]' in the example with the UID of a shared folder that your Secrets Manager has access to.

var newRecord = new KeeperRecordData{type = "login", title = "Sample KSM Record: C#"};

newRecord.fields = new[]
{
    new KeeperRecordField { type = "login", value = new[] { "My Username" } },
    new KeeperRecordField { type = "password", value = new[] { CryptoUtils.GeneratePassword() } },
};
newRecord.notes = "This is a C# record creation example";

var recordUid = await SecretsManagerClient.CreateSecret(options, folderUid, newRecord);

Custom Type Example

This example creates a record with a custom record type.

Replace '[FOLDER UID]' in the example with the UID of a shared folder that your Secrets Manager has access to.

var newRecord = new KeeperRecordData();
newRecord.type = "Custom Login";
newRecord.title = "Sample Custom Type KSM Record: C#";
newRecord.fields = new[]
{
    new KeeperRecordField { 
        type = "host", 
        value = new[] 
        {
            new Dictionary<string, string>
            {
                { "hostName", "127.0.0.1"},
                { "port", "8080"}
            }
        },
        label = "My Custom Host lbl",
        required = true
    },
    
    new KeeperRecordField { 
        type = "login", 
        value = new[] { "[e-mail]" }, 
        required = true, 
        label = "My Custom Login lbl"
    },
    
    new KeeperRecordField
    {
        type = "password", 
        value = new[] { CryptoUtils.GeneratePassword() }, 
        required = true, 
        label = "My Custom Password lbl"
    },
    
    new KeeperRecordField
    {
        type = "url",
        value = new[] { "http://localhost:8080/login" },
        label = "My Login Page",
        required = true
    },
    
    new KeeperRecordField { 
        type = "securityQuestion", 
        value = new[]
        {
            new Dictionary<string, string>
            {
                {"question", "What is one plus one (write just a number)"}, 
                { "answer", "2" }
            }
        }, 
        label = "My Question 1",
        required = true
    },
    
    new KeeperRecordField {

        value = new[]
        {
            new Dictionary<string,string>
            {
                { "region", "US" },
                { "number", "510-444-3333" },
                { "ext", "2345" },
                { "type", "Mobile" }
            }
        }, 
        label = "My Private Phone", 
        privacyScreen = true
    },

    new KeeperRecordField
    {
        type = "date", 
        value = new[] {(object) 1641934793000 }, 
        label = "My Date Lbl"
    },
    
    new KeeperRecordField {

        {
            new Dictionary<string, string>
            {
                {"first", "John"},
                {"middle", "Patrick"},

    new KeeperRecordField
    {
        type = "oneTimeCode", 
        value = new[]
        {
            "otpauth://totp/Example:[e-mail]?secret=JBSWY3DPEHPK3PXP&issuer=Example"
        }, 
        label = "My TOTP",
        required = true
    }
};
newRecord.notes = "\tThis custom type record was created\n\tvia Python SDK copied from https://docs.keeper.io/secrets-manager/secrets-manager/developer-sdk-library/.net-sdk";

var recordUid = await SecretsManagerClient.CreateSecret(options, "[FOLDER_UID]", newRecord);

Delete a Secret

The .Net KSM SDK can delete records in the Keeper Vault.

Delete Secret

DeleteSecret(smOptions, recordsUids);

Example

using SecretsManager;

// setup secrets manager
var storage = new LocalConfigStorage("ksm-config.json");
//SecretsManagerClient.InitializeStorage(storage, "<One Time Access Token>");
var smOptions = new SecretsManagerOptions(storage);

// delete a specific secret by record UID
await SecretsManagerClient.DeleteSecret(smOptions, new string[] {"EG6KdJaaLG7esRZbMnfbFA"});

Caching

To protect against losing access to your secrets when network access is lost, the .Net SDK allows caching of secrets to the local machine in an encrypted file.

Setup and Configure Cache

In order to setup caching in the .Net SDK, include a caching post function as the second argument when instantiating aSecretsManagerOptions object.

The .Net SDK includes a default caching function cachingPostFunction which stores cached queries to a file.

var options = new SecretsManagerOptions(storage, SecretsManagerClient.CachingPostFunction);
var secrets = await SecretsManagerClient.GetSecrets(options);

Folders

Folders have full CRUD support - create, read, update and delete operations.

Read Folders

Downloads full folder hierarchy.

Task<KeeperFolder[]> GetFolders(SecretsManagerOptions options)

Response

Type: KeeperFolder[]

Example Usage

using SecretsManager;

var options = new SecretsManagerOptions(new LocalConfigStorage("ksm-config.json"));
var folders = await SecretsManagerClient.GetFolders(options);

Create a Folder

Requires CreateOptions and folder name to be provided. The folder UID parameter in CreateOptions is required - UID of a shared folder, while sub-folder UID is optional and if missing, a new regular folder is created directly under the parent (shared folder). There's no requirement for the sub-folder to be a direct descendant of the parent shared folder - it could be many levels deep.

Task<string> CreateFolder(SecretsManagerOptions options, CreateOptions createOptions, string folderName, KeeperFolder[] folders = null)

public class CreateOptions {
    public string FolderUid { get; }
    public string SubFolderUid { get; }
}

public class KeeperFolder {
        public byte[] FolderKey { get; }
        public string FolderUid { get; }
        public string ParentUid { get; }
        public string Name { get; }
}

Example Usage

using SecretsManager;

var options = new SecretsManagerOptions(new LocalConfigStorage("ksm-config.json"));
var co := new CreateOptions("[PARENT_SHARED_FOLDER_UID]");
var folderUid = await SecretsManagerClient.CreateFolder(options, co, "new_folder");

Update a Folder

Updates the folder metadata - currently folder name only.

Task UpdateFolder(SecretsManagerOptions options, string folderUid, string folderName, KeeperFolder[] folders = null)

Example Usage

using SecretsManager;

var options = new SecretsManagerOptions(new LocalConfigStorage("ksm-config.json"));
await SecretsManagerClient.UpdateFolder(options, "[FOLDER_UID]", "new_folder_name");

Delete Folders

Removes a list of folders. Use forceDeletion flag to remove non-empty folders.

When using forceDeletion avoid sending parent with its children folder UIDs. Depending on the delete order you may get an error - ex. if parent force-deleted child first. There's no guarantee that list will always be processed in FIFO order.

Any folders UIDs missing from the vault or not shared to the KSM Application will not result in error.

Task DeleteFolder(SecretsManagerOptions options, string[] folderUids, bool forceDeletion = false)

Example Usage

using SecretsManager;

var options = new SecretsManagerOptions(new LocalConfigStorage("ksm-config.json"));
await SecretsManagerClient.DeleteFolder(options, new string[]{"[FOLDER_UID1]", "[FOLDER_UID2]"}, true);
