Vault Configuration¶

You can configure pg_tde to use HashiCorp Vault as a global key provider for managing encryption keys securely.

Note

This guide assumes that your Vault server is already set up and accessible. Vault configuration is outside the scope of this document, see Vault’s official documentation for more information.

Example usage¶

    SELECT pg_tde_add_global_key_provider_vault_v2(
        'provider-name',
        'secret_token',
        'url',
        'mount',
        'ca_path'
    );

Parameter descriptions¶

provider-name is the name to identify this key provider
secret_token is an access token with read and write access to the above mount point
url is the URL of the Vault server
mount is the mount point where the keyring should store the keys
[optional] ca_path is the path of the CA file used for SSL verification

The following example is for testing purposes only. Use secure tokens and proper SSL validation in production environments:

    SELECT pg_tde_add_global_key_provider_vault_v2(
        'my-vault',
        'hvs.zPuyktykA...example...ewUEnIRVaKoBzs2',
        'http://vault.vault.svc.cluster.local:8200',
        'secret/data',
        NULL
    );
