acra-keymaker #

We recommend using acra-keys for Acra 0.95.0 and newer.

Command line flags #

General flags #

• --client_id=<id>

  Use provided ClientID as identifier to generate keys or keypairs.

• --tls_cert=<path>

  Path to TLS certificate to use as ClientID identifier. Works only when passed empty ClientID: --client_id="".

• --tls_identifier_extractor_type={distinguished_name|serial_number}

  Decide which field of TLS certificate to use as ClientID.

  • distinguished_name — certificate Distinguished Name (DN)
  • serial_number — certificate serial number

By default, certificate Distinguished Name is used as ClientID.

• --keystore=<v1|v2>

  Set keystore format. Read more about keystore versions.

  This option is required for newly created keystores. If --keys_output_dir points to existing keystore then acra-keymaker automatically detects the version of the keystore.

Storage destination #

Filesystem #

• --keys_output_dir=<path>

  Path to keystore directory.

  Default is .acrakeys.

• --keys_public_output_dir=<folder>

  Path to public key directory for --keystore=v1 format. (Ignored for --keystore=v2.)

  Default is .acrakeys.

Redis #

• --redis_db_keys=<number>

  Redis database number to use. Default is 0.

• --redis_host_port=<host:port>

  Address of Redis database to use as keystore. If not specified, Redis is not used.

• --redis_password=<password>

  Password to Redis database.

Configuration files #

• --config_file=<path>

  Path to YAML configuration file.

• --dump_config

  Dump configuration to configs/acra-keymaker.yaml.

• --generate_markdown_args_table

  Generate markdown file with text description of all flags. Output file is configs/markdown_acra-keymaker.md. Works in a pair with --dump_config.

HashiCorp Vault #

acra-keymaker can read ACRA_MASTER_KEY from HashiCorp Vault instead of environment variable.

• --vault_connection_api_string=<url>

  Connection string (like https://example.com:8200) for connecting to HashiCorp Vault. If not specified, ACRA_MASTER_KEY environment variable will be used.

• --vault_secrets_path=<kv-path>

  Path to KV Secrets directory in Vault used to store ACRA_MASTER_KEY. Default is secret/.

• --vault_tls_ca_path=<path>

  Path to CA certificate bundle to use for HashiCorp Vault certificate validation.

  If not specified, use root certificates configured in system.

• --vault_tls_client_cert=<path>

  Path to client TLS certificate used to connect to HashiCorp Vault.

  If not specified, don’t send client certificate.

• --vault_tls_client_key=<path>

  Path to the private key of the client TLS certificate used to connect to HashiCorp Vault.

  If not specified, don’t send client certificate.

• --vault_tls_transport_enable={true|false}

  Use TLS to encrypt transport with HashiCorp Vault. Default is false.

Generating keys #

Note: Back up all your keys before calling acra-keymaker with any flag described below. Some keys can be rotated, and the previous keys will be retained, while some keys will be overwritten.

Acra master key #

• --generate_master_key=<path>

  Generate a new random master key and write it to the specified file.

  Acra components might expect this key in ACRA_MASTER_KEY environment variable or read from KMS.

Note: When you generate a new key (or keypair), the existing key is rotated. That is, the new key becomes the default for encryption in AcraServer while the previous key is archived and used only for decryption.

Transport keys #

• --generate_acraconnector_keys

  Generate a new transport keypair for AcraConnector.

• --generate_acraserver_keys

  Generate a new transport keypair for AcraServer.

• --generate_acratranslator_keys

  Generate a new transport keypair for AcraTranslator.

AcraServer & AcraTranslator keys #

• --generate_acrawriter_keys

  Generate a new storage keypair for data encryption/decryption with AcraStruct.

• --generate_hmac_key

  Generate a new symmetric key for HMAC calculation and searchable encryption.

• --generate_log_key

  Generate a new symmetric key for audit logging.

• --generate_poisonrecord_keys

  Generate a new keypair and symmetric key for poison records.

• --generate_symmetric_storage_key

  Generate a new symmetric key for data encryption/decryption with AcraBlock.

AcraServer & AcraAuthManager keys #

AcraAuthManager tool is deprecated and will not be available since 0.91.0.

• --generate_acrawebconfig_keys

  Generate a new symmetric key for encrypting AcraWebconfig’s basic authentication credentials.

  Note: This key cannot be rotated. Newly generated key replaces the current one.
