Input Arguments

collapse all

Secret key name to identify the secret, specified as a unique string. If the name contains spaces, keyName must be surrounded by double quotes (").

Wildcards (*) are supported at the end of the secret name. For example, "myapp1.*".

Example: "my password"

Secret key value, specified as a string. The value is encrypted and stored in the MATLAB Web App Server vault. You can retrieve the value from a web app using the getSecret (MATLAB) function.

If the value contains spaces, keyValue must be surrounded by double quotes (").

Example: "AdL3DS2$CyMEgCQQCo9+BpMoYQJxRF+j6ctTi3"

Scope value, specified as any static string or a string with macros. The scope can specify users, groups, or specific web apps to allow access to the designated secret.

The following macros are supported:

  • $UserID—the log on session User ID. To use this macro, you must include userinfo.json in the config/webapps_private directory. For details, see Customize Web App Behavior Based on User.

  • $AppName—the web app name, which includes the CTF file name and folder name.

If a secret has a scope other than the default, you must specify the scope value using the --scope argument when calling set-attributes, get-attributes, list, or remove.

Example: "$AppName.$UserID"

Attribute name, specified as a string. An attribute is unencrypted metadata that is stored along with the secret key name and encrypted value in the webapps_secrets XML file. The attribute name describes the associated attribute value, specified by attrValue.

Example: port

Attribute value, specified as a string. An attribute is unencrypted metadata that is stored along with the secret key name and encrypted value in the webapps_secrets XML file. The attribute value is described by the associated attrName.
