» 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"
}
