»alicloudkms Seal

The AliCloud KMS seal configures Vault to use AliCloud KMS as the seal wrapping mechanism. The AliCloud KMS seal is activated by one of the following:

  • The presence of a seal "alicloudkms" block in Vault's configuration file.
  • The presence of the environment variable VAULT_SEAL_TYPE set to alicloudkms. If enabling via environment variable, all other required values specific to AliCloud KMS (i.e. VAULT_ALICLOUDKMS_SEAL_KEY_ID) must be also supplied, as well as all other AliCloud-related environment variables that lends to successful authentication.

»alicloudkms Example

This example shows configuring AliCloud KMS seal through the Vault configuration file by providing all the required values:

seal "alicloudkms" {
  region     = "us-east-1"
  access_key = "0wNEpMMlzy7szvai"
  secret_key = "PupkTg8jdmau1cXxYacgE736PJj4cA"
  kms_key_id = "08c33a6f-4e0a-4a1b-a3fa-7ddfa1d4fb73"
}

seal "alicloudkms" {  region     = "us-east-1"  access_key = "0wNEpMMlzy7szvai"  secret_key = "PupkTg8jdmau1cXxYacgE736PJj4cA"  kms_key_id = "08c33a6f-4e0a-4a1b-a3fa-7ddfa1d4fb73"}

»alicloudkms Parameters

These parameters apply to the seal stanza in the Vault configuration file:

  • region (string: <required> "us-east-1"): The AliCloud region where the encryption key lives. May also be specified by the ALICLOUD_REGION environment variable.

  • domain (string: "kms.us-east-1.aliyuncs.com"): If set, overrides the endpoint AliCloud would normally use for KMS for a particular region. May also be specified by the ALICLOUD_DOMAIN environment variable.

  • access_key (string: <required>): The AliCloud access key ID to use. May also be specified by the ALICLOUD_ACCESS_KEY environment variable or as part of the AliCloud profile from the AliCloud CLI or instance profile.

  • secret_key (string: <required>): The AliCloud secret access key to use. May also be specified by the ALICLOUD_SECRET_KEY environment variable or as part of the AliCloud profile from the AliCloud CLI or instance profile.

  • kms_key_id (string: <required>): The AliCloud KMS key ID to use for encryption and decryption. May also be specified by the VAULT_ALICLOUDKMS_SEAL_KEY_ID environment variable.

»Authentication

Authentication-related values must be provided, either as environment variables or as configuration parameters.

Note: Although the configuration file allows you to pass in ALICLOUD_ACCESS_KEY and ALICLOUD_SECRET_KEY as part of the seal's parameters, it is strongly recommended to set these values via environment variables.

AliCloud authentication values:

* `ALICLOUD_REGION`
* `ALICLOUD_ACCESS_KEY`
* `ALICLOUD_SECRET_KEY`

AliCloud authentication values:
* `ALICLOUD_REGION`* `ALICLOUD_ACCESS_KEY`* `ALICLOUD_SECRET_KEY`

Note: The client uses the official AliCloud SDK and will use environment credentials, the specified credentials, or RAM role credentials in that order.

»alicloudkms Environment Variables

Alternatively, the AliCloud KMS seal can be activated by providing the following environment variables:

Vault Seal specific values:

* `VAULT_SEAL_TYPE`
* `VAULT_ALICLOUDKMS_SEAL_KEY_ID`

Vault Seal specific values:
* `VAULT_SEAL_TYPE`* `VAULT_ALICLOUDKMS_SEAL_KEY_ID`
