CryptoKeyManager Component

Properties   Methods   Events   Config Settings   Errors  

The CryptoKeyManager component provides a simple way to load, generate and manage generic crypto keys.

Syntax

TsbxCryptoKeyManager

Remarks

CryptoKeyManager allows you to load, save, generate, import, and export low-level crypto keys. One example of such keys are raw RSA keys stored in PKCS1 format or AES256 keys. CryptoKeyManager supports asymmetric, symmetric, and HMAC keys.

CryptoKeyManager is a typical companion for low-level cryptography classes, such as PublicKeyCrypto, SymmetricCrypto, and HashFunction. It can also be used to provide external key material to certificate objects, and to derive cryptographic keys from passwords.

Use ImportBytes or ImportFromFile method to load the key material from a buffer or file. Use ImportFromCert (and remember to assign the certificate object to the Certificate property before calling it) to import a key from an X.509 certificate. Once loaded, the key will be available in the Key property.

To generate a new key or keypair use Generate method. You can export the generated key using ExportBytes or ExportToFile method. You can attach the generated or loaded key to an external certificate object using the ExportToCert method.

Note: CryptoKeyManager can only work with one cryptographic key at a time. Use CryptoKeyStorage to access media containing more than one key.

Config Method (CryptoKeyManager Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

__property TsbxCryptoKeyManagerNotificationEvent OnNotification = { read=FOnNotification, write=FOnNotification };

Remarks

The component fires this event to let the application know about some event, occurrence, or milestone in the component. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.

PasswordNeeded Event (CryptoKeyManager Component)

This event is fired when a decryption password is needed.

Syntax

typedef struct {
  String NeededFor;
  String Password;
  bool Cancel;
} TsbxCryptoKeyManagerPasswordNeededEventParams;
typedef void __fastcall (__closure *TsbxCryptoKeyManagerPasswordNeededEvent)(System::TObject* Sender, TsbxCryptoKeyManagerPasswordNeededEventParams *e);
__property TsbxCryptoKeyManagerPasswordNeededEvent OnPasswordNeeded = { read=FOnPasswordNeeded, write=FOnPasswordNeeded };

Remarks

The component fires this event when a password is needed to decrypt a certificate or a private key.

In the handler of this event, assign the password to the Password parameter, or set Cancel to true to abort the operation.

The NeededFor parameter identifies the certificate for which the password is requested.

Config Settings (CryptoKeyManager Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.
