Alibaba Cloud Auth is an authentication method that verifies Alibaba Cloud users through signature validation, allowing secure access to Infisical resources.
The following sequence diagram illustrates the Alibaba Cloud Auth workflow for authenticating Alibaba Cloud users with Infisical.

At a high level, Infisical authenticates an Alibaba Cloud user by verifying its identity and checking that it meets specific requirements (e.g., its ARN is whitelisted) at the /api/v1/auth/alicloud-auth/login endpoint. If successful,
then Infisical returns a short-lived access token that can be used to make authenticated requests to the Infisical API.
To be more specific:
GetCallerIdentity request using an Alibaba Cloud user's access key secret; this is done using an HMAC sha1 algorithm./api/v1/auth/alicloud-auth/login endpoint.In order to sign requests, you must have an Alibaba Cloud user with credentials such as access key ID and secret. If you're unaware of how to create a user and obtain the needed credentials, expand the menu below.

In the following steps, we explore how to create and use identities for your workloads and applications on Alibaba Cloud to access the Infisical API using request signing.
To create an identity, head to your Organization Settings > Access Control > Identities and press Create identity.
When creating an identity, you specify an organization-level role for it to assume; you can configure roles in Organization Settings > Access Control > Organization Roles.
Input some details for your new identity:
Once you've created an identity, you'll be redirected to a page where you can manage the identity.
Since the identity has been configured with Universal Auth by default, you should reconfigure it to use Alibaba Cloud Auth instead. To do this, click the cog next to Universal Auth and then select Delete in the options dropdown.
Now create a new Alibaba Cloud Auth Method.
Here's some information about each field:
2592000 equivalent to 30 days): The lifetime for an access token in seconds. This value will be referenced at renewal time.2592000 equivalent to 30 days): The maximum lifetime for an access token in seconds. This value will be referenced at renewal time.0): The maximum number of times that an access token can be used; a value of 0 implies an infinite number of uses.0.0.0.0/0, allowing usage from any network address.In order to allow an identity to access project-level resources such as secrets, you must add it to the relevant projects.
To do this, head over to the project you want to add the identity to and navigate to Project Settings > Access Control > Machine Identities and press Add Identity.
Select the identity you want to add to the project and the project-level role you want it to assume. The project role given to the identity will determine what project-level resources this identity can access.
To access the Infisical API as the identity, you need to construct a signed GetCallerIdentity request and then make a request to the /api/v1/auth/alicloud-auth/login endpoint passing the signed data and signature.
Below is an example of how you can authenticate with Infisical using NodeJS.
import crypto from "crypto";
// We highly recommend using environment variables instead of hardcoding these values
const ALICLOUD_ACCESS_KEY_ID = "...";
const ALICLOUD_ACCESS_KEY_SECRET = "...";
const params: { [key: string]: string } = {
Action: "GetCallerIdentity",
Format: "JSON",
Version: "2015-04-01",
AccessKeyId: ALICLOUD_ACCESS_KEY_ID,
SignatureMethod: "HMAC-SHA1",
Timestamp: new Date().toISOString(),
SignatureVersion: "1.0",
SignatureNonce: crypto.randomBytes(16).toString("hex"),
};
const canonicalizedQueryString = Object.keys(params)
.sort()
.map((key) => `${encodeURIComponent(key)}=${encodeURIComponent(params[key])}`)
.join("&");
const stringToSign = `GET&%2F&${encodeURIComponent(canonicalizedQueryString)}`;
const signature = crypto
.createHmac("sha1", `${ALICLOUD_ACCESS_KEY_SECRET}&`)
.update(stringToSign)
.digest("base64");
const res = await fetch(
"https://app.infisical.com/api/v1/auth/alicloud-auth/login",
{
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
identityId: "...", // Replace with your identity ID
Signature: signature,
...params,
}),
},
);
const json = await res.json();
console.log("Infisical Response:", JSON.stringify(json));
If an identity access token expires, it can no longer access the Infisical API. A new access token should be obtained by performing another login operation.
