# DI and direct classes

The facade is the recommended default, not the only way in. Crypto has three equivalent entry points, and all three run the same code:

- The Crypto facade — the shortest form, used throughout these docs.
- The manager, RoundlyConsulting\\Crypto\\CryptoManager — the facade root, injected through the constructor. Same API, an explicit dependency and no static calls.
- The classes the facade fronts — RsaKey, Jws, Token, Certificate and the rest — called directly. The core factories need no container, config or disk.

## Inject the manager

CryptoManager is a final container singleton with no constructor arguments, so the injected instance is the exact object the facade calls:

```php
use RoundlyConsulting\Crypto\CryptoManager;

final class IssueApiToken
{
    public function __construct(private CryptoManager $crypto) {}

    public function __invoke(): string
    {
        return $this->crypto->random()->token(48);
    }
}

// Or resolve it — a container singleton, the exact object the facade calls:
app(CryptoManager::class)->keys()->rsa()->generate(3072);
```

## Call the classes directly

Each class works on its own — the form every feature section shows as the alternative to the facade:

```php
use RoundlyConsulting\Crypto\Jose\Jws;
use RoundlyConsulting\Crypto\Random\Token;
use RoundlyConsulting\Crypto\Signature\Key\RsaKey;
use RoundlyConsulting\Crypto\X509\Certificate;

$key         = RsaKey::private($pem);        // core factories need no container, config or disk
$code        = Token::numeric(6);
$certificate = Certificate::fromDer($der);
$jws         = new Jws;
```

## No action classes

Crypto has no action classes. It is stateless computation, so it exposes plain service objects rather than one action per method: the sub-accessors are final, hold no state, and every method forwards to one static factory. The table maps each facade method to the class it fronts:

| Facade method | Fronts |
| --- | --- |
| `jws()` | `new Jose\Jws` |
| `jwk() · jwkFromArray() · jwkFromJson()` | `Jwk::fromPublicKey() · Jwk::fromArray() · Jwk::fromJson()` |
| `x509()->fromPem() · fromDer() · fromBase64()` | `Certificate::fromPem() · fromDer() · fromBase64()` |
| `x509()->chain()->fromX5c() · fromPems() · fromPemBundle() · fromCertificates()` | `Chain::fromX5c() · fromPems() · fromPemBundle() · new Chain()` |
| `keys()->rsa() · keys()->ec() · keys()->hmac()` | `RsaKey::… · EcKey::… · HmacSecret::… (same method names)` |
| `keys()->ed25519()->public*() · private*() · generate()` | `OkpKey::ed25519*() · fromSecretKey() / secretKeyFrom*() · generate()` |
| `hs() · rs() · es() · eddsa() · verifier()` | `new Hs · new Rs · new Es · new EdDSA · new KeyVerifier` |
| `ecDer()->fromRaw() · toRaw() · isValid()` | `Der::fromRaw() · Der::toRaw() · Der::isValid()` |
| `hmac() · digest() · hkdf() · constantTimeEquals()` | `new Hmac · new Digest · new Hkdf · ConstantTime::equals()` |
| `aes256Gcm()` | `new Aead\Aes256Gcm` |
| `derDecoder() · cbor()` | `new DerDecoder · new CborDecoder` |
| `coseKey() · authenticatorData()` | `CoseKey::fromCbor() · AuthenticatorData::parse()` |
| `totp() · hotp() · provisioningUri()` | `new Totp · new Hotp · ProvisioningUri::totp()` |
| `random()->bytes() · token() · numeric() · alphanumeric() · fromAlphabet() · secret()` | `Bytes::generate() · Token::urlSafe() · Token::numeric() · Token::alphanumeric() · Token::fromAlphabet() · Secret::base32()` |
| `base64Url* · base64* · base32* · hex* (Encode / Decode)` | `Base64Url · Base64 · Base32 · Hex — ::encode() / ::decode()` |
