Credentials storage, _(*2)

Backends

This API supports the following backends:, _(*3)

• Files
• Environment variables
• Hashicorp's Vault
• KeePass databases
• Docker Secrets

Files

Via the FromFile class. Files are expected to have the following format:, _(*4)

rest_password=abcdefg
ldap_password=qwertzu

Environment variables

Via the FromEnvironment class. Credential names map to environment variables by uppercasing them and replacing forward slashes by two underscores:, _(*5)

use security\credentials\{Credentials, FromEnvironment};

$credentials= new Credentials(new FromEnvironment());
$secret= $credentials->named('ldap_password');     // Reads $ENV{LDAP_PASSWORD} => util.Secret

Hashicorp's Vault

Via the FromVault class. Credentials are read from the backend mounted at /secret., _(*6)

use security\credentials\{Credentials, FromVault};

// Set token to NULL to use VAULT_TOKEN from environment
$token= new Secret('72698676-4988-94a4-...');

$credentials= new Credentials(new FromVault('http://127.0.0.1:8200', $token));
$secret= $credentials->named('ldap_password');     // Reads ldap_password key from /secret

$credentials= new Credentials(new FromVault('http://127.0.0.1:8200', $token, 'vendor/name'));
$secret= $credentials->named('mysql');             // Reads mysql key from /secret/vendor/name

KeePass databases

Via the KeePass class., _(*7)

use security\credentials\{Credentials, FromKeePass};
use util\Secret;

$secret= new Secret('key');

$credentials= new Credentials(new FromKeePass('database.kdbx', $secret));
$secret= $credentials->named('ldap_password');     // Reads top-level entry ldap_password

$credentials= new Credentials(new FromKeePass('database.kdbx', $secret, 'vendor/name'));
$secret= $credentials->named('mysql');             // Reads mysql entry in vendor/name subfolder

Docker secrets

See https://docs.docker.com/engine/swarm/secrets/. Uses Docker's default locations on both Windows and Un*x systems if constructed without argument., _(*8)

use security\credentials\{Credentials, FromDockerSecrets};
use util\Secret;

$credentials= new Credentials(new FromDockerSecrets());
$secret= $credentials->named('ldap_password');     // Reads top-level entry ldap_password
