Login to SDM -> Administration tab -> Options Manager -> Web Services -> hmac_algorithm. If this option is installed, the cryptographic hash function provided by NX.env variable NX_HMAC_ALGORITHM (supported algorithms are HmacSHA1, HmacSHA256, HmacSHA384, HmacSHA512, and HmacMD5), Set your Authorization Type to:  Basic Auth, Populate a Username / Password with correct values. 3) Switch to the Headers tab and ensure that the Authorization shows up as Basic with a base-64 encrypted string next to it. Key Vault eliminates the need to store credentials in your applications. Azure Key Vault allows you to securely store and manage application credentials such as secrets, keys, and certificates in a central and secure cloud repository. Normalize the request header string into canonical form. This article gives a high-level overview and other considerations while implementing the Secret Key Authentication in CA SDM REST API. HTTP Signature authentication is provided by a Base-64 encoded transaction key, represented in a string format. Authentication . Ensure there is communication between the client (a third-party program of your choice) and the SDM REST server. 7) Client sends the request data, the signature and the Access Key to SDM. Options Manager, Web Services, hmac_algorithm, The signature, a Keyed-Hash based Message Authentication Code (, HMAC - Hash-based Message Authentication Code, the cryptographic hash function provided by NX.env variable, HmacSHA1, HmacSHA256, HmacSHA384, HmacSHA512. Basically , the Authorization header must be in the format: the string "SDM" space and the base-64 encoded username/password of a CA SDM User. The information can be verified and trusted because it is digitally signed using a secret (with the HMAC algorithm) or a public/private key pair (RSA or ECDSA). First the client needs to obtain an access_key and secret_key from CA SDM REST API. 9) SDM uses the request data and the Secret Key to generate the signature using the same hash algorithm the Client used. 6.2. For example, with SSH keys you can 1. allow multiple developers to log in as the same system user without having to share a single password between them; 2. revoke a single develop… The profile name is specified in square brackets (for example, [default]), followed by the configurable fields in that profile as key-value pairs. The benefit of this whole process is that knowing your username and password won't be enough to hack your accounts. The information in this article has been included in our product documentation. CA SDM uses the request data and the Secret Key to generate the signature using the same hash algorithm the Client used. 2. Secret Double Octopus is the most secure Active Directory identity protection platform with friction-free user experience taking your authentication to a whole new level. There is a space character after Base,  leave it as is. 4. For this, we need to be able to do the HMAC encryption of the string that we need to request. During authentication, random numbers are generated and exchanged, similar to the shared secret key protocol. secret_key: Authentication in the XML API Service Using the CLI utility secret_key is another way to generate a key that can be used in XML API calls for authentication in Plesk. Server will now allow access to anyone who can prove they have the corresponding private key. However, using public key authentication provides many benefits when working with multiple developers. Secret keys should be changed periodically. API Keys were created as somewhat of a fix to the early authentication issues of HTTP Basic Authentication and other such systems. 4) This secret_key needs to be used thereafter by the client to be able to properly authenticate itself as the valid client against the SDM REST server. ... users have to provide their secret passwords, which are verified by the server. 3. var secret = "2504166E48DC19294B86773F798DEE7996D3973E"; postman.setGlobalVariable("hmac", encodeURIComponent(CryptoJS.enc.Base64.stringify(CryptoJS.HmacSHA1(str, secret)))); Here the secret key is what we got as a response for, Here, it is a literal string of CA SDM followed by a space, followed by the access-key from CA SDM that we obtained in, Authorization: SDM 1842290659:jkd32qsCPwaBcWH0NX93V8zu6sI%3D, , , , , , System_AHD_generated, , . Keep these two handy, you’ll need them. IC authentication, Secret keys 1. If you have other second steps set up, use your security key to sign in whenever possible. 11) Add the X-Obj-Attrs header key with values:  userid,last_name  (basically we are trying to get the userid, last_name field values from the resource:   /caisd-rest/cnt ), Authorization: SDM 1842290659:jkd32qsCPwaBcWH0NX93V8zu6sI%3D. Key pair is created (typically by the user). Shared secret keys can also be used to authenticate credentials. Follow appropriate steps that you would normally do, to install an SDM option. Like Basic authentication, API key-based authentication is only considered secure if used together with other security mechanisms such as HTTPS/SSL. This is done by doing a POST to  /caisd-rest/rest_access, 2) Change the Type now to  No Auth  and click the Save button. The installation folder contains few samples inÂ, $NX_ROOT/samples/sdk/rest/java/test2_auths, $NX_ROOT/samples/sdk/rest/java‘SampleSDMAuth.java’, ‘SampleUsingSecretKey.java’ and ‘HMACUtil.java, Create Access Key and Secret from CA SDM REST API:Â, The client must obtain an access_key and secret_key from SDM REST API. For more information, see REST HTTP Methods -REST Secret Key Authentication. This is done by creating a Pre-Request script section of Postman. For more information, see, Consider the following before you implement the Secret Key Authentication in CA SDM REST API:Â. For Key, enter the Secret Key displayed underneath the barcode in Step 2. Client sends the request data, the signature and the Access Key to CA SDM. If the ciphertext fails verification, crypto_secretbox_open raises an exception. REST HTTP Methods -REST Secret Key Authentication. Key-Based Authentication (Public Key Authentication) Key-based authentication is a kind of authentication that may be used as an alternative to password authentication. Create a new application and once you are done you should have your consumer token and secret. Prerequisites and Considerations. If the signature generated by CA SDM matches the signature sent by the Client, then the request is considered authentic, otherwise the request is discarded and CA SDM returns an error response. CA Service Desk Manager's REST API supports Secret Key Authentication. If the two match, the secret key has been determined. Private key stays with the user (and only there), while the public key is sent to the server. This is basically going to encrypt the resource string:  GET\n/caisd-rest/cnt  and the secret key together and encode it using the HmacSHA1 algorithm. A problem with the secret key authentication is the secure distribution of the secret key. 15) The response would be something like: , , , , , System_AHD_generated, , . Sure it went beyond API Key based Authentication and that's fine because if you are going to explain how to build a solution, you should include all the elements (creating the database, what type of project pieces you are going to need, dependency injection, etc.). The screen should look like: Note: Basically , the Authorization header however, HAS to be in this format, the string "SDM" space, the base-64 encoded username/password of the SDM user. Typically with the ssh-copy-id utility. This option can be set to a preferred value, and install the option (In our case, we'll set it to hmacSHA1). In the client authentication method explained in the previous section, the signature of the client assertion is generated using a shared key (i.e. Before you can send requests for CyberSource REST API services that are authenticated using HTTP Signature, you must create a shared secret key for your CyberSource merchant account in the Business Center. You can leave rest of the information as is. Unfortunately I never saved these when I set up TFA on my devices. 9) Go to the Authorization tab and change the Authorization to look like below instead: It is literal string SDM  followed by a space, followed by the access-key from SDM that we obtained in Step#6, followed by  literal string    :{{hmac}}. Store it in a safe place that only you can access. 1) Make sure communication between the client (a 3rd party program of some sort) and the SDM REST server, one should first consider implementing HTTPS between these two components. client secret). 10) If the signature generated by SDM matches the signature sent by the Client, then the request is considered authentic, otherwise, the request is discarded and SDM returns an error response. 3) SDM  secret_key is a 40 character alphanumeric sequence, dynamically generated by SDM during REST access key creation. How to Use the Secret Key Authentication with REST API? With OAuth 2.0 the process to authenticate was: Get your Client ID and client secret from the Manage App page. You can find further details here: https://docops.ca.com/ca-service-management/14-1/en/building/building-ca-service-desk-manager/ca-sdm-rest-api/how-to-use-the-secret-key-authentication-with-rest-api, Release: SDMU0M99000-14.1-Service Desk Manager-Full License, CA Service Desk Manager - Unified Self Service, CA Service Management - Asset Portfolio Management, CA Service Management - Service Desk Manager, SampleSDMAuth.java’, ‘SampleUsingSecretKey.java’, https://docops.ca.com/ca-service-management/14-1/en/reference/ca-service-desk-manager-reference-commands/technical-reference/rest-http-methods#RESTHTTPMethods-RESTSecretKeyAuthentication, the header fields (eg; date, accept) provided by NX_STRING_TO_SIGN_FIELDS  (if the option is not installed) in the same order. The other party proves its knowledge of the key by … Everybody has access to the public key of a node, while the private key is secret. GET /something HTTP/1.1 X-API-Key: abcdef12345 or as a cookie: GET /something HTTP/1.1 Cookie: X-API-KEY=abcdef12345 API keys are supposed to be a secret that only the client and server know. This secret_key is encrypted before it is stored in the SDM database (usp_rest_access table). You must first consider implementing the HTTPS between these two components. CA SDM Server gives the following response: , , , 1503521363, 2504166E48DC19294B86773F798DEE7996D3973E.
