Default Value

""

Remarks

Data Type

Byte Array

KeyNonce Property (CryptoKeyStorage Component)

A nonce value associated with a key.

Syntax

Data Type

Boolean

KeySubject Property (CryptoKeyStorage Component)

This property is read-only and not available at design time.

Data Type

Byte Array

Syntax

__property bool KeyValid[int KeyIndex] = { read=FKeyValid };

Default Value

false

Remarks

Returns True if this key is valid. The term Valid highly depends on the kind of the key being stored. A symmetric key is considered valid if its length fits the algorithm being set. The validity of an RSA key also ensures that the RSA key elements (primes, exponents, and modulus) are consistent.

The KeyIndex parameter specifies the index of the item in the array. The size of the array is controlled by the KeyCount property.

This property is read-only and not available at design time.

Data Type

Boolean

Use Open method to open a storage.

This property is read-only and not available at design time.

Data Type

Boolean

PinnedKeyHandle Property (CryptoKeyStorage Component)

Allows to get or set a 'handle', a unique identifier of the underlying property object.

Default Value

0

Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation. pdfSigner.setSigningCertHandle(certMgr.getCertHandle());

This property is not available at design time.

Config Method (CryptoKeyStorage 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).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Syntax

String __fastcall GetStorageProperty(String PropName);

Remarks

This method, together with SetStorageProperty, provides an extensible way of managing the certificate storage's settings that are not available through the primary properties of the component. The list of settings may be extended in future, in response to emergence of new storage variants and recognition of non-obvious storage usage scenarios.

Currently no custom properties are available for this component.

Syntax

String __fastcall ListStores();

Remarks

The contents of the list depends on the type of the store used and the parameters it is opened with. For PKCS#11 stores the method returns a list of slot descriptions for all slots published by the driver.

The store identifiers are separated from each other with a CRLF sequence.

Login Method (CryptoKeyStorage Component)

Signs in to a session or elevates the session rights.

Syntax

void __fastcall Login(int SessionType, String Pin, bool ReadOnly);

Remarks

Use this method to sign in to a session with a required access type. Note that in some cases you may call this method more than one time for a specific session to elevate your access rights, for example: // open an unauthenticated session storage.Login(stUnauthenticated, "", false); // elevate the access rights for the session storage.Login(stUser, "password", false); Sessions are currently supported for PKCS#11 storage types only.

Logout Method (CryptoKeyStorage Component)

Signs out of an opened session.

Syntax

void __fastcall Logout(bool CloseSesion);

Remarks

Use this method to sign out of a session. Pass true to CloseSession to shut the session down altogether.

This method is currently support for PKCS#11 storage type only.

Open Method (CryptoKeyStorage Component)

Opens existing storage or creates one in memory.

Syntax

void __fastcall Open(String StorageID);

Remarks

Use this method to open the storage with the given StorageID. Key storages can come from several different locations, detailed below.

• localmachine
• currentservice

host is either "localhost", an IP address, or FQDN.

params are chosen from this list:

• store (required), is the name of the Windows store to access (e.g. "MY")

user is the username used to access the device.

pin is the pin code used to access the device.

driverpath is the path to the driver used to access the device.

params are chosen from this list:

• slot, the token slot to access on the device. If not provided, one will be chosen automatically.
• readonly, whether to access the device with only read permissions. Use 0 for false, and 1 for true.

Example: pkcs11://john.doe:1234@/c:/windows/system32/asepkcs.dll?slot=0&readonly=1

KMIP Server

A storage can be opened from a KMIP server using this syntax: mailto:{password}@{remotehost}:{remoteport}/?{params}

password is the password use to authenticate to the server.

remotehost is the FQDN to the server.

remoteport is the server port to connect to.

params are chosen from this list:

• encoder, the message encoding used to communicate with the server. Possible values are:
  • 1 (XML)
  • 2 (JSON)
  • 3 (TTLV)

SetStorageProperty Method (CryptoKeyStorage Component)

Sets the value of a custom key storage property.

Syntax

void __fastcall SetStorageProperty(String PropName, String PropValue);

Remarks

This method, together with GetStorageProperty, provides an extensible way of managing the certificate storage's settings that are not available through the primary properties of the component. The list of settings may be extended in future, in response to emergence of new storage variants and recognition of non-obvious storage usage scenarios.

Currently no custom properties are available for this component.

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 key or certificate for which the password is requested.

Config Settings (CryptoKeyStorage 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.
