Creating a Secret

When you create a secret on CSMS for secret hosting, the secret value will be stored in the original secret version, which is marked as SYSCURRENT.

Secret value, the detailed content of a secret, is used to verify user identity or authorization during authentication. It can be of various forms, depending on the used authentication mechanism. Typical secret values include:

Username and password: A username is the identity of a user, and a password is the key secret value for user identity authentication.
Digital certificate: The public key and identity, which are the secret values of a certificate, are used to verify the identity of a user or device.
Key pair: The private key, which is the secret value, is used for signature and decryption.
Token: A token is a temporary secret value used for identity authentication.
Biometric recognition information: Biometric feature data, such as fingerprint, facial recognition, and iris recognition, is the secret value.
One-time password (OTP): An OTP generated via SMS, email, or a certain application is the secret value.

Constraints

At most 500 secrets can be created on CSMS.
A secret can be no larger than 64 KB.
By default, the default key csms/default created by CSMS is used as the encryption key of the current secret. You can also create a user-defined symmetric key and use a user-defined encryption key on the KMS console.

Creating a Shared Secret

Log in to the DEW console.
Click in the upper left corner and select a region or project.
In the navigation pane on the left, choose Cloud Secret Management Service > Secrets.

Click Create Secret. Configure parameters in the Create Secret dialog box, as shown in Figure 1. For details about the parameters, see Table 1.

KMS Encryption Key	The following modes are supported: Select from list: Select this if you want to use the key used or shared by the current account. Select the default key csms/default or a custom key created on KMS. Enter: Enter the ID of the authorized key. Enter an encryption key if an authorized key is used. Only symmetric algorithm key IDs are supported. Do not enter an asymmetric key ID. NOTE: CSMS encrypts secret values using the encryption key provided by KMS. When you use the KMS encryption function, KMS creates a default key csms/default for you to use. For details about how to create a custom key on KMS, see Creating a Key. After a grant is created, you can switch to the manual input mode, and enter the key ID to use the granted key for encryption. For details, see Creating a Grant.

Deleting a Secret

Before deleting a secret, ensure that it is not in use and will not be used.

A secret will not be deleted until its scheduled deletion period expires. You can set the period to a value within the range 7 to 30 days. Before the specified deletion date, you can cancel the deletion if you want to use the secret. If the scheduled deletion period of a secret expires, the secret will be deleted and cannot be restored.
For details about the billing information about a secret to be deleted, see Are Credentials Scheduled to Be Deleted Billed?
If you delete a secret immediately, you can restore it using the secret backup that you have downloaded in advance. Exercise caution when performing this operation.

In the navigation pane on the left, choose Cloud Secret Management Service > Secrets.
Locate the target secret and click Delete.
On the displayed page, select a deletion mode. If you want to delete the secret in a specific time, set Schedule deletion.
