Applies to: Machine Learning Server, Microsoft R Server 9.x
Machine Learning Server, formerly known as Microsoft R Server, uses tokens to identify and authenticate the user who is sending the API call within your application. Users must authenticate when making an API call. They can do so with the 'POST /login HTTP/1.1' API call, after which Machine Learning Server issues a bearer token to your application for this user. Alternately, if the organization is using Azure Active Directory (AAD), users receive a bearer token from AAD when they authenticate.
Oct 02, 2015 SSH Config and crypto key generate RSA command. Use this command to generate RSA key pairs for your Cisco device (such as a router). Keys are generated in pairs–one public RSA key and one private RSA key. If your router already has RSA keys when you issue this command, you will be warned and prompted to replace the existing keys with new keys.

How to: Create a public-private key pair.; 2 minutes to read; In this article. To sign an assembly with a strong name, you must have a public/private key pair. This public and private cryptographic key pair is used during compilation to create a strong-named assembly. You can create a key pair using the Strong Name tool (Sn.exe).
Before you can clone a repo over SSH, you must first set up your SSH keys in GitKraken. Navigate to Preferences Authentication. Under General, you may choose an SSH key pair by browsing your file system, or let GitKraken generate a key for you (recommended).Make sure that you copy your public SSH key and paste it into your remote hosting service! First up, two references: My SecItem attributes for keys post clarifies the meaning of each of the ‘label’ / ‘tag’ attributes on a key. The errSecDuplicateItem reference documentation explains key uniqueness. There’s one ‘obvious’ issue here, namely that you’re setting kSecAttrApplicationTag to a string instead of a Data value. This is not surprising because there’s much.
This bearer token is a lightweight security token that grants the “bearer” access to a protected resource, in this case, Machine Learning Server's core APIs for operationalizing analytics. After a user has been authenticated, the application must validate the user’s bearer token to ensure that authentication was successful.
Important
For proper access token signing and verification across your configuration, ensure that the JWT settings are exactly the same for every web node.

Security Concerns
Despite the fact that a party must first authenticate to receive the token, tokens can be intercepted by an unintended party if the token is not secured in transmission and storage. While some security tokens have a built-in mechanism to protect against unauthorized parties, these tokens do not and must be transported in a secure channel such as transport layer security (HTTPS).
If a token is transmitted in the clear, a man-in the middle attack can be used by a malicious party to acquire the token to make an unauthorized access to a protected resource. The same security principles apply when storing or caching tokens for later use. Always ensure that your application transmits and stores tokens in a secure manner.
You can revoke a token if a user is no longer permitted to make requests on the API or if the token has been compromised.
Create tokens
The API bearer token's properties include an access_token / refresh_token pair and expiration dates.
Tokens can be generated in one of two ways:
- If Active Directory LDAP or a local administrator account is enabled, then send a 'POST /login HTTP/1.1' API request to retrieve the bearer token.
- If Azure Active Directory (AAD) is enabled, then the token comes from AAD.
Example: Token creation request
- Request
- Response
Token Lifecycle
The bearer token is made of an access_token property and a refresh_token property.
The 'access_token' Lifecycle | The 'refresh_token' Lifecycle | |
---|---|---|
Gets Created | Whenever the user logs in, or a refreshToken api is called | Whenever the user logs in |
Expires | After 1 hour (3660 seconds) of inactivity | After 336 hours (14 days) of inactivity |
Becomes Invalid | If the refresh_token was revoked, or If not used for 336 hours (14 days), or When a new pair of access_token/refresh_token has been created | If not used for 336 hours (14 days), or When the refresh_token expires, or When a new access_token/refresh_token pair was created, or If the refresh_token was revoked |
Use tokens
As defined by HTTP/1.1 [RFC2617], the application should send the access_token directly in the Authorization request header.
You can do so by including the bearer token's access_token value in the HTTP request body as 'Authorization: Bearer {access_token_value}'.
When the API call is sent with the token, Machine Learning Server attempts to validate that the user is successfully authenticated and that the token itself is not expired.
- If an authenticated user has a bearer token's access_token or refresh_token that is expired, then a '401 - Unauthorized (invalid or expired refresh token)' error is returned.
- If the user is not successfully authenticated, a '401 - Unauthorized (invalid credentials)' error is returned.
Examples
Example HTTP header for session creation:
Example HTTP header for publishing web service:
Renew tokens
A valid bearer token (with active access_token or refresh_token properties) keeps the user's authentication alive without requiring him or her to re-enter their credentials frequently.
The access_token can be used for as long as it’s active, which is up to one hour after login or renewal. The refresh_token is active for 336 hours (14 days). After the access_token expires, an active refresh_token can be used to get a new access_token / refresh_token pair as shown in the following example. This cycle can continue for up to 90 days after which the user must log in again. If the refresh_token expires, the tokens cannot be renewed and the user must log in again.
To refresh a token, use the 'POST /login/refreshToken HTTP/1.1' API call.
Example: Refresh access_token
- Example request:
- Example response:
Revoke refresh tokens
A refresh_token should be revoked:
- If a user is no longer permitted to make requests on the API, or
- If the access_token or refresh_token have been compromised.
Use the 'DELETE /login/refreshToken?refreshToken={refresh_token_value} HTTP/1.1' API call to revoke a token.
Example: Revoke token

Note
Although .NET Core supports strong-named assemblies, and all assemblies in the .NET Core library are signed, the majority of third-party assemblies do not need strong names. For more information, see Strong Name Signing on GitHub.
There are a number of ways to sign an assembly with a strong name:
- By using the Signing tab in a project's Properties dialog box in Visual Studio. This is the easiest and most convenient way to sign an assembly with a strong name.
- By using the Assembly Linker (Al.exe) to link a .NET Framework code module (a .netmodule file) with a key file.
- By using assembly attributes to insert the strong name information into your code. You can use either the AssemblyKeyFileAttribute or the AssemblyKeyNameAttribute attribute, depending on where the key file to be used is located.
- By using compiler options.
You must have a cryptographic key pair to sign an assembly with a strong name. For more information about creating a key pair, see How to: Create a public-private key pair.

Create and sign an assembly with a strong name by using the Assembly Linker
![Please Please](/uploads/1/2/5/7/125758003/547649062.png)
At the Developer Command Prompt for Visual Studio, enter the following command:
al/out:<assemblyName> <moduleName>/keyfile:<keyfileName>
Where:
- assemblyName is the name of the strongly signed assembly (a .dll or .exe file) that Assembly Linker will emit.
- moduleName is the name of a .NET Framework code module (a .netmodule file) that includes one or more types. You can create a .netmodule file by compiling your code with the
/target:module
switch in C# or Visual Basic. - keyfileName is the name of the container or file that contains the key pair. Assembly Linker interprets a relative path in relation to the current directory.
The following example signs the assembly MyAssembly.dll with a strong name by using the key file sgKey.snk.
For more information about this tool, see Assembly Linker.
Sign an assembly with a strong name by using attributes

- Add the System.Reflection.AssemblyKeyFileAttribute or AssemblyKeyNameAttribute attribute to your source code file, and specify the name of the file or container that contains the key pair to use when signing the assembly with a strong name.
- Compile the source code file normally.NoteThe C# and Visual Basic compilers issue compiler warnings (CS1699 and BC41008, respectively) when they encounter the AssemblyKeyFileAttribute or AssemblyKeyNameAttribute attribute in source code. You can ignore the warnings.

Sign an assembly with a strong name by using the compiler
Compile your source code file or files with the
/keyfile
or /delaysign
compiler option in C# and Visual Basic, or the /KEYFILE
or /DELAYSIGN
linker option in C++. After the option name, add a colon and the name of the key file. When using command-line compilers, you can copy the key file to the directory that contains your source code files.For information on delay signing, see Delay-sign an assembly.
